The quality of life in the house or urban apartment directly depends on the good functioning of all communications. It also concerns the sewage system, which due to improper arrangement, the use of low-quality materials or long-term operation can periodically malfunctions. So what to seal the joints of the sewer pipes when the leaks occurs and how to perform the procedure correctly and promptly?
In case of leakage of sewage pipes, first of all, it will be necessary to install, in which place it happens. As a rule, the most vulnerable seal of the sewage system made of cast iron products are tube joints. Do not be a frequent phenomenon is the appearance on the surface of the product of various defects and damage through which water and seeps outward.
If we are talking about the leakage of the joints, the main reason for such a trouble is the unscrupulousness of the plumbers who performed the sewage installation.
If the leakage concerns the pipe itself, then such a phenomenon may occur in the following cases:
If it happened so that the sewer pipe is flowing on the junction, then the following actions can be taken:
There are also situations where the leakage occurs in the soluble solutions used in the previously used solution. If so, the places of cracks need to be thoroughly dry and smeared through the sealant (on silicone basis) or the entire polycemental solution.
If the question arises about how to smell the joints of the sewer pipes, then it is worth paying special attention to special self-adhesive tapes. Such products are one of the newest and more efficient methods of insulation compounds of sanitary pipes, which has a lot of significant advantages:
High-quality sealing of the junction of sewer pipes can be carried out and by means of a sealant, which has a silicone or rubber base. Such a means is distinguished by good adhesion with a surface, which allows you to make a cast-iron pipe even without prior processing by primers.
Depending on the type of hardener, the sewers can be processed by the following sealants:
If it happened so that the sewer tube occurs on the junction, then, with the right approach, it is possible to solve this problem on your own very simple and quickly.
Only if the installation of the sewer system is made reliably and efficiently, the possibility of leakage appearance will be completely excluded. To do this, it is necessary to carry out the installation and laying of pipes.
All connections must be necessarily sealed. After laying sewage, builders necessarily check its tightness. Even the minimum flow is not allowed.
The Commission will take the design and sign an act of the suitability of the object only if the sewage flow is detected. Over time, the butt joints of the sewer tubes begin to flow.
How to deal with such a phenomenon, what measures need to be taken to avoid flowing, how to seal sewer pipes?
This material appeared on the construction market quite recently. The tape was specifically designed for sealing sewer joints. The film has a white color, wounds on the spool. The ribbon width does not have a standard value. Each manufacturer independently sets this size.
Advantages of self-adhesive tape:
disadvantages
The tape is bad to enter the hitting of ultraviolet rays. It cannot be carried out by mounting open sewage.
If you need to create a hermetic connection right on the street, it is necessary to cover the self-adhesive film to close with any sunscreen material.
Professionals use such self-adhesive film and for other purposes. It began to use it often when you need to create a hermetic compound of fittings and other shaped parts.
In order for the work to be done qualitatively, the preparation of the surface of the pipe is first. It should not be mud clusters. After cleaning the pipe is dried.
Then the soil layer is applied and the surface is subjected to drying. On the past preparation, the surface of the pipe passes the tape. It is wound around the problem area in the form of a spiral.
To achieve good tightness, each new layer of tape must capture half the previous layer. Multiple layers are usually wound. This pipe will be completely sealed.
Important! When winding should not form folds. Even very small folds can cause leaks. Be careful, make winding tightly and prevent the appearance of wrinkles.
The basis of this material is the rubber. In principle, such sealants consist of a mixture of a variety of substances. They create high-quality sealing.
It must be said that the adhesion of silicone sealants is characterized by very high indicators. Therefore, it does not require additional surface treatment with special primers for applying sealant.
Depending on the type of hardener, such sealants have several varieties.
The cost of such silicone sealants is not very high. However, they can only be used on certain surfaces. They cannot be sealing the pipes, if acid is moving on them.
This type of material is considered universal. They can seal plastic and metal sewage products. Silicone paste exposed to the process of vulcanization becomes a substance resembling rubber.
Professional advice! In order not to have complications in the extrusion of the sealant, you can use the mounting pistol. If there is no gun, you can insert the hammer handle inside the tube and pressed. The handle will play the role of the piston.
Of course, except for silicone sealant, there are other substances for sealing sewer systems.
Epoxy resin. This composition has long established itself as an excellent helper in pipe sealing. It is often used in living conditions when the docking of sewer pipes is carried out or their repair.
Portland cement. This component is part of very many sealing mixtures. It applies when it is necessary to create an asbestos-cement mixture. Portland cement is used to booze the fuseal compounds of cast-iron sewer pipes.
Bitumen. The substance used to obtain a mixture that the sealing of the joints is performed. They are processed by crops on ceramic pipelines.
Rope from hemp. It is used in the technological process for processing chip-iron and ceramic sewage pipes. The highest effect gives the combination of resin impregnation with a jute rope. Such sealing will never give the leakage.
Technical sulfur. Most often used for the processing of butt compounds on the crop-iron grows. Before processing the butt connection, sulfur is crushed and warm up until it starts to melt.
This modern substance consists of several components. The basis is epoxy resin, in which special fillers have been added. Due to their properties, it turns out a composition that gives the necessary quality and high superficial adhesion to the product being processed.
Therefore, the surface roughness of the processed parts only contributes to a more reliable clutch.
With its appearance, "cold welding" is very similar to plasticine, in which several colors mixed.
Before starting to use such a "welding" plasticine, it is necessary to spin well until all colors are mixed and do not get the same shade.
After that, a harvested mixture is tightly pressed into a carefully stripped, dried and skim surface. After complete frozen, it completely covers the crack.
High adhesion is considered very important advantage of such a material. It perfectly falls on the surface where moisture is constantly present. Thanks to an excellent clutch, "cold welding" very quickly eliminates the flow formed in the junction of the sewer tube. Complete drying of "cold welding" can continue within 24 hours. However, to say exactly how much time you need to dry out, quite difficult. It all depends on the temperature conditions and the amount of material from which the mixture was made.
While the mixture does not dry completely, it is prohibited to use the sewage.
In addition to the materials listed above, professionals also use other known substances for sealing:
In everyday life, epoxy resin remains the most popular today. To use it to use a special polyethylene polyamine hardener if cold screwdrive occurs.
If this process occurs under heating, a maleic anhydride is used.
Sometimes the hardener is manufactured from other materials with similar properties. Preparation of epoxy sealant is made in proportion (10: 1 or 5: 1).
Technical sulfur applies to process sewage release. First, it is crushed, then heated until a plastic state is obtained. Heated sulfur is poured directly to the release area.
To process the cast iron products the greatest effect shows the hemp rope covered with a resin.
Asphalt mastic or petroleum bitumen is used to process existing joints of ceramic products.
To dock the riser made with the cast iron pipe, you need to insert one pipe into the socket on the end of another. The resulting junction is sealed with a special sealant.
The whole process is performed by experienced masters in a certain technological sequence.
An ordinary linen package closes the gap formed between the pipes. It is added to the depth of more than 2/3 of the size of the gap and well condensed.
Small advice! If there is no linen pack, it will greatly replace the scenario hemp.
Then portland cement is mixed with water (1: 9) and this mixture closes the remaining free gap in the riser.
Good to know! To get a mixture, you can use the cement, mixing it with fiber from asbestos (2: 1). Before you start pouring such a mixture into a pipe, you need to add a small portion of water.
The materials described above can be replaced with modern silicone sealant. It in the ready-made form is poured into the existing gap. In order for it instantly does not dry, it is necessary to pre-close its application to pre-close the polyethylene film.
When repairs start in the old house, one serious problem arises. It is necessary to dock modern plastic pipes with old cast iron products. This situation requires a mandatory competent approach.
Works are performed in the following sequence:
Such a technology if it is carried out strictly on items, will make it possible to obtain a reliable connection that is distinguished by great strength and good tightness.
In the future, this compound will not create trouble, leaks in such places are completely excluded.
On the presented video, you can see how work on sealing and independent waterproofing of sewage pipes are carried out.

Sealing of jacks of sewer pipes requires the most responsible approach, since the depressurization of the system entails sad consequences. If this happens with the inner open system, for example, in the apartment, then an unpleasant smell will appear in the housing or even the estones will begin to leak out, overpassing the room.
The depressurization of the outer system leads to soil contamination, groundwater, etc. In addition, groundwater with soil can leak into the pipe, as a result of which the system will stop functioning.
Ensure reliable and high-quality sealing is capable of sealant. This remedy is sold in tubes in the form of pasta. It is based on silicone rubber, as well as a rather complicated mixture of various synthetic substances.
The sealing process This means looks like this:
Thus, the joints of all parts are obtained hermetic.
In private homes, sealing is required not only by the sewer system itself, but also the place of entering pipes.
As a rule, the sealing assembly of inputs is carried out using rubber performance and sealing cuffs.
Among the characteristics of the sealant can be distinguished by the following quality:
It is thanks to these qualities a sealant for sewage pipes and is very popular.
First of all, it should be said that for sewer systems, an exceptionally silicone sealant should be used. It is on sale two species:
So, how to seal the sewer system, we figured out. Now consider how to apply this tool.
It should be noted that the instruction on the assembly of the pipeline using the sealant is extremely simple:
In the process of frozen the sealant, moisture should not fall on it so that it acquires the necessary properties for the time specified by the manufacturer.
As we see, this process is extremely simple, so even an inexperienced person can cope with him. True, it should be noted that only a plastic pipeline is collected according to such a scheme. If the pig-iron pipes, work is performed somewhat differently:
If you need to connect cast iron pipes with plastic, you should take advantage of special rubber adapters.
Before connecting, they should also be treated with sealant.
Here, perhaps, all information that will allow you on your own without much difficulty to ensure the tightness of the joints of the sewer pipes.
obustroeno.com.
From construction practice it is known that re-closeing the joints of the sewage pipes and deformed seams in terms of work is comparable to the arrangement of the system "from scratch". Therefore, approach this process should be with all seriousness.
Important! Combining outdoor sewers, it is necessary to eliminate the presence of leaks not only from the inside of the pipeline, but also inside it. So you will avoid overflowing the drainage system that may arise from penetration into it groundwater.
The following materials are most popular today:
The most popular are measures based on silicone.
In addition, the modern industry produces special funds. So, if you are looking for than to seal the sewage pipes made from ceramics, pay attention to the oil bitumen and asphalt masts. It will be the best choice. And it is possible to reliably close the fusey joints of cast-iron pipes using technical sulfur.
Silicone sealants. This material is a mastic capable of hardifying under the influence of air. One of the advantages of silicone sealant is the absence of the need to pre-process the surface of the pipes in prime. For its manufacture, silicone rubber is used, which includes special additives, reinforcing the degree of adhesion and, accordingly, the strength of the sealing layer.
Performing work takes at least time and does not require professional skills. A mounting gun is applied to extrude. If there is no one at hand, and the sewer pipe flows at the joints, you can use a simple hammer whose handle will serve as a piston. Upon completion of the vulcanization process, silicone mastic will turn into a substance similar to its properties with rubber.

Cement mortar and resin harness. Sealing sewer pipes with these materials is a classic method of eliminating leaks. It is performed by a 2/3 zackecan, from the depth of the crossing with a smallest harness, followed by the fill in the remaining 1/3 of the cement mortar made on the basis of the M300 cement. Cement mortar is prepared in proportion of 1: 9.
Those owners of housing, who are looking for how to close the joints of the sewer pipe with the smallest labor costs, it is recommended to use a special expanding waterproof cement. In this case, they will be able to seal the problem space without a smallest harness. It is determined by the fact that such cement quickly solidifies and at the same time expands. The solution must be prepared immediately before use, mixing cement with water in proportion 1: 2.5.
Important! The pipe compound should be centered, secured and only after that thoroughly fill the cooked mixture.
Self-adhesive ribbon. This material is rightfully considered a highly efficient sealant. In addition, the tape is inherent in dielectric and anti-corrosion properties. Not a latter role in its high popularity plays simplicity.
Self-adhesive tape, or fum-tape, is used to seal the taps, inserts, plugs, rotary angles, and, of course, when the sewage pipe is flowing at the junction. In the latter case, you must perform a definite sequence of actions. First stage ˗ Preparation of surfaces of jammed pipes to the upcoming procedure by purifying from dirt and dust. Daving the surfaces to dry, if required, treat them with primer.
Next, the tape neatly with a good constant tension is turned on the helix around the pipes connected. In this case, it is necessary to prevent the formation of any, even small, folds. To reliably sewer, wind pipes with 50% launch. Then the surfaces and actually the joint themselves will be closed with two layers of self-adhesive tape.
Cold welding is a mixture of epoxy resin with special fillers. It is they who give the created product the required qualities, including durable surface adhesion. Thus, the roughness present on the joined surfaces only contributes to their more reliable adhesion with each other.
In appearance, cold welding resembles two-color plasticine. Before use, it must be used and mix both colors until a homogeneous shade is obtained. Then this mixture should be pressed as quickly as possible to the brilliance of a cleaned, dried and carefully degreased place of flow.
One of the essential advantages of this material is an excellent clutch with a surface on which moisture is present. Thus, if the tube of sewage in the junction leaks, the use of cold welding allows you to quickly seal the current flow.
The connection created in this way will be reliable after 1 ˗ 24 hours. The exact time depends on the amount of material used and thermal conditions. But in any case, for this period you will have to abandon the use of sewage.
If the cast-iron sewage pipeline flows, the owner of the house can replace the damaged segment of the tube cut from the same material. But there is an alternative option in the form of a plastic product. However, in this case, it is necessary to know the nuances of how to sew the pipe of the sewage consisting of components differing in their characteristics.
To achieve a good result, first of all, you should purchase rubber or polymer adapters. Having done this, you can start work. First you need to clean the cast-iron fool from rust and contaminants. To improve the level of tightness, it is recommended to be reduced it. Next, a layer of silicone sealant is applied to the inner surface of the socket. The same operation must be performed on the outer surface of the adapter nozzle. Then, this element of the structure is neatly introduced into the socket. Upon completion of the polymerization process, the nozzle along with the plastic part is connected to the pipeline. In case there is no spare pipe, the optimal solution to the leakage will be the use of a metal clamp.
You can purchase such an attachment with a rubber seal, and you can cut the suitable piece of solely on your own. Clamp is generally a universal solution to many problems related to pipe repair.
Helpful advice! For a better result on a problem space in one, and then the two layers are superimposed with rubber gaskets, after which this design is tightened with screws.
You should not discount the easiest way to seal the joints of sewage pipes: seal them with paint. Although this method is rarely used, it also gives good results. And on any kind of sewer pipes. It is performed in two stages: at the beginning of the socket, it is necessary to score cloth and pour its paint. Then with a screwdriver, the contents of the terminus are well tumped. After the mass of the resulting mass, it is possible to start exploiting the repaired drainage system of wastewall.
The following factors affect the choice of a suitable sealing of sealing pipes: the location of the pipeline and the material from which it is made. But know: You can do this work with your own hands. To do this, it is enough to clearly put yourself a task, carefully examine the instructions for the use of a particular material and follow the prompts of common sense.

The sewer is securely sealed at the installation phase. During operation, the internal system is regularly examined to detect and eliminate leaks on time. Wastewater should not flow, and the sewage itself should not fall from the outside, because It is capable of violating her work and lead to serious breakdowns.
Special attention should be paid to the sealing of pipes located underground, since they are much more difficult to repair if leaks occur. If the system's work is broken due to groundwater from entering it, you will have to make a lot of effort to determine.
Careful sealing at the stage of construction of the sewer system prevents problems such as:
For installation of sewage systems, pipes from different materials are used, and suitable sealant should be selected for each type of pipes. Also, the selection depends on the installation technology and the target destination of each individual system element.
Many different materials are used to seal the compounds of sewer pipes:
Each sealing material has its own varieties, features, appointment and scope of application.
There are ordinary and foil self-adhesive tapes. They are designed to seal the compounds of water and sewer pipes and have unique properties. The tapes include bitumen-polymeric materials, so that they are absolutely waterproof.
Depending on the range of operating temperatures, there are three main varieties of ribbons:
For insulation of sewage pipes indoors, a summer or winter sealing tape is suitable, and it is better to choose winter for external work.
The benefits of material include such properties:
The unique characteristics and strength of sealing tapes make it possible to use them at any temperatures and practically in any conditions. The life of the adhesion coating is at least 30 years. During this time, the tape does not lose its properties and retains one hundred percent tightness.
So that the material does not lose its properties for a long time, it must be applied correctly. The stage of surface preparation is very important. They are thoroughly cleaned from old coatings, degreased and dried.
It is necessary to monitor the uniformity and tension force of the tape during the winding of the pipe and make wide adhesions equal to half of the width of the material. If the tape is applied correctly, the surface will be covered with two protective layers.
Silicone sealants use silicone sealants for processing the joints of sewage systems. Another option is polyurethane compositions. They are universal, suitable for sealing and gluing a variety of designs and elements. The optimal solution is to buy a special plumbing composition based on silicone, picking it up with the material and operating conditions of the system.
The composition of silicone includes rubber, due to which the finished material is distinguished by high elasticity and adhesion to any reasons. When using silicone sealants, you do not need to process the surface with primems to improve the clutch.
Depending on the composition of the hardener, two main types of silicone sealants are distinguished:
Silicone sealants are usually used to treat plastic and metal sewage joints. After polymerization, they form dense elastic coatings resembling rubber. Due to its high elasticity, they are well tolerated load and do not crack.
Sealants are applied using mounting pistols that squeeze the contents of the packaging. The joints are treated across the circumference. The line must be continuous so that no gaps remain. After applying the composition of the seams, we carefully smash with a special soft spatula or wet finger in a glove.
Technical sulfur is made by refining petroleum products. It can be powder or commercial and sold in construction stores. This is a good option for sealing the junctions of cast iron pipes. Additional plus - low price.
The sulfur is crushed (if bought compelling), heated to the melting point (about 130-150 ° C), then poured into the space of the termination. When the material freezes, it will turn into a dense waterproof mass. His only drawback is low elasticity.
Portland cement is indispensable for many types of work. The material includes clinker, gypsum, calcium silicates. The dry mixture is bred by water until a thick solution is obtained. It quickly freezes, forming a high-strength frost-resistant and water-repellent monolith.
Special additives add special additives in the cement mixture to increase its elasticity. This allows you to securely seal the joints of cast iron pipes. The material is resistant to temperatures, it is well tolerating freezing-size, so it is successfully used in the arrangement of external sewage.
Epoxy resin - universal glue, which can help and when installing sewage. To prepare a sealing composition, the epoxy resin is mixed with a hardener. The proportions depend on the material brand and are indicated in the instructions for use.
When mixing the resin and the hardener, it is important to strictly follow the manufacturer's recommendations, otherwise the time of frozen composition and operational properties of the finished coating may change.
Curses of ceramic pipes are often poured with bitumen materials. Bitumen-rubber, bitumen-polymer mastic has been proven excellent. By type of application they are divided into cold and hot.
To use pipe sealing, it is better to use cold apparent compositions, because They are much easier to use, and the works themselves are safer. The only minus of such sealants for sewerage pipes is somewhat more expensive.
To seal the joints of cast-iron and ceramic sewer tubes, hemp and jute ropes are traditionally used, resin strand. These are cheap and easy-to-use materials, however, according to its technical and operational properties, they are significantly inferior to modern sealants.
For sewage pipes, it is better to use sanitary silicone or polyurethane sealants. Their quality and durability can vary greatly depending on the manufacturer, so pay attention to the brands and choose the most reliable.
Sealants of trademarks Ceresit. and Moment out of competition. They are reliable, durable, distinguished by high elasticity and curb with any surfaces. If it is possible to acquire the compositions of these brands, do not hesitate, because You pay not just "for the name", but for real quality.
There are still 6 brands producing decent products:
Sometimes heightened requirements for any individual performance characteristics are presented to sealants. In such cases, it makes sense to carefully study the descriptions of manufacturers and consult with sellers.
For example, the best sealant for premises with an increased fire hazard - the universal composition of Krass; For complex compounds - "Moment of ger"; For ceramic pipes - Belinka Belsil Sanitary Acetate; And for premises with constant high humidity - Ceresit CS 25 or S 400.
In the process of sealing the sewer system, many questions arise. We offer video footage that will help to cope with difficulties and independently perform all the work.

Detailed instructions for the sealing of the sewer pipe termination when switching from cast iron on plastic:
Whatever the type of sealant for sewer pipes you have chosen, you need to carefully prepare the surfaces and efficiently perform work. There should be no cracks and fistula on the pipes. Before sealing, they are cleaned, repaired, degrease. When working, it is necessary to strictly adhere to technology, and after it is completed to wait for the time to frozen the composition. Only after that the system can be operated as usual.

The first skill that is obligatory for a novice plumber is the ability to qualitatively seal the threaded connections of pipelines, fittings and equipment. When assembling water supply systems, heating and sewage systems, in any case, threaded compounds requiring seals are formed. A poor-quality seal will entail water leakage with all the ensuing consequences. Publication gives a detailed overview of how to solve this technical task, methodology and algorithm of actions.
There are several basic ways to compact the threaded compounds, they are divided according to the material used:
White thread, has a special oily paste-shaped impregnation, sealing formable joint. The material is universal in application - it can withstand temperatures up to 130 degrees Celsius, pressure up to 16 atmospheres (for gas - up to 8 atm.).
The simplicity of application of this winding is due to an uncomplicated method - the thread is wounds arbitrarily, not on the thread, with a non-silver tension. The polymer is wound on the right-hand thread - clockwise. The number of turns for each diameter is given in a special table on the packaging.
For plastic threads, the number of turns specified in the table is increased by 30%.
Thread universal for mounting joints in plumbing, but in general has some limitations. No need to use material in zones with a temperature of more than 130 degrees (steam and high-temperature heating), the polymer thread is not always neutral to chemically aggressive environments.
The cost of the thread among the sealing materials is on the upper step, but the simplicity of use with interest justifies costs.
Threaded compounds of a certain type are compacted by special gaskets. Mainly gaskets come complete with the product. Most often gaskets apply with the following elements:
Compression fittings of plastic pipelines (except polypropylene) are sealed with rubber gaskets of round-section, pre-installed on the fitting body. When installing a flexible liner in a precipitant, a rubber laying is inserted (as in the case of a washing machine).
Special devices and communications are compacted by gaskets of various sections and materials. Pressure gauges are usually mounted on a paronite gasket, a Sgona type "American" has an inner round gasket and so on.
Len is no less popular among professional plumbers than thread and other types of materials. This is due to the fact that at one time he was the only type of seal and therefore most of the plumbing specialists acquired the sealing skill in working precisely with this material. In working with this material at the first stage for a beginner, certain difficulties may occur.
The second important factor in popularity is the availability and low cost of the material. There is a general method of sealing flax, there are some features. Features can be allocated as follows:
The first option is the simplest. First, the number of revolutions installed the part is determined. The element comes into a thread without winding, the number of complete revolutions is considered. After the winding, the element turns out to be calculated or a slightly smaller number of revolutions - with a greater number you can damage the fitting or crane.
From the moster of flax, a strand of material 6 - 8 mm wide is separated. It is cleaned from transversely directed fibers. The edge of the strands is pressed with the finger at the beginning of the thread (the start of the thread in this case is the border of the turns in the middle of the fitting, the crane). The material is wound tightly through the coils of the thread, rows with an adhesive in 2 - 3 mm, until the end of the thread. The winding is slightly wetted - this reduces the likelihood of stuffing the material with a retracted product.
The second and third option are the configurations of the first. The best is considered to apply a special sealing paste. It compacts the connection, protects flax from decomposition.
Paint as a sealing substance is now practically not used. With prolonged service, the paint dries and cracks, often disrupts the joint density. Disassembling compounds with paint also causes difficulties - it is necessary to apply large physical efforts, while you can damage the fitting or crane.
When buying flax, you need to pay attention to the following aspects:
The tape is a polymeric material product, has a minor thickness. It is used mainly on communications with low pressure and temperature, for sealing compounds with a diameter of no more than 20 - 25 mm.
The installation technique has a general algorithm with flax - rows of tapes are cooled to rotate the thread with the imposition of neighboring rows by 2 - 3 mm. The number of layers is determined arbitrarily.
The tape applies most often with newcomers, in simple household connections. The disadvantages of the material are:
The advantage of FUM tape is simplicity, low cost, ease of replacement.
Anaerobic sealing gel has a sealing technique other than previous methods and materials. Sealants of this type are divided into substances of medium and strong fixation.
Sealants are used most often on metal threads, plastic has to be treated with a special activator. Metal threads are predefined, degreased, dried. Then the gel is applied - on 3 - 4 thread turns are filled with deposits and protrusions, the monolith gel is not disturbed.
After that, the installed item is wrapped from the hand, the excess gel is removed. The average time of complete hardening sealant is 2 hours.
The use of such a seal is inherent in newcomers and will cause bewilderment from a professional. Each plumbing system should easily understand for repair, prevention or replacement of individual elements. The sealant works high quality and makes the compounds practically intimidating. Recommended dismantling method - heating with a hairdryer to 150 degrees - not applicable for plastic pipes, and this is now the main type of material for plumbing sphere.
In any case, the choice of material for sealing compounds depends on the desire and availability of the abilities in humans. It is necessary to proceed from the specific conditions of application, the desired quality of the future installation, the period of operation and the possible replacement of seals, pipelines, equipment.
What is a sealant for sewage cast iron pipes and how to choose the right stake material? One of the main tasks facing the master at the final construction stage is to prevent leaks that appear in the sewer system.
Sealant for sewer tubes must be chosen, given the fact that it has a significant diameter and more length.
Sealing sewer pipes is necessary to prevent the penetration of uncleanness into the apartment and eliminate the unpleasant odor in residential premises.
To solve the problem of junction sealing, it is necessary to relate quite seriously.
Having reveaning the reason for the malfunction, interfering with the cast iron pipe, the owner can spend the whole cycle of necessary work to eliminate it.
Causes of pipe leakage are diverse:
As for the choice of insulating material, special anti-corrosion tape coatings should be used here. With their help, it makes the joints between the pipes, the sealing of coupling nodes, inserts, taps belonging to the sewer system.

What is the sealing tape, isolating the sewer pipe? The basis of the product is a bitumen-rubber mixture and a protective film.
The peculiarity of the material is that it has a high degree of strength, it is used to work with various compositions, not destroyed for a long time.
It is possible to avoid unpleasant effects of leakage by sealing the joints with silicone composition. Two types of materials are used for work:
Seeling defects with the help of neutral composition will cost the owner much more expensive than working with acid insulation. The use of silicone is economically profitable, since the material has significant adhesion.
As for the use of other sealing formulations, then the following types can be chosen here:
The sealing of the joints is carried out using silicone adhesives made according to TU 6-15-1822-95, GOST 6-02-4-53-96.
The Cylconic insulating material is a composition based on rubber, and consisting of filler, hardener and catalyst. The material of the vulcanization of the material is in the range from +60 to + 200 ° C.
Silicone sealant for repairing pipes in the sewage system has a density of 2.0 g / cm³, dries at a temperature of + 20 ° C in 150 minutes. The characteristics of the tensile strength are even more diverse, constituting from 16 to 20 kgf / cm² and the material-dependent material.
The peculiarity of the sealant is that the volcanizer has high adhesion to steel, copper, aluminum, silicone glue, concrete. Silicone sealant is resistant to adverse atmospheric influences, solvents, synthetic and mineral oils.
When repairing the pipe does not cause pollution of the environment toxic substances, since silicone materials belong to the 4th grade of low-wave agents. Sealant is used for gluing and sealing joints and connectors when repairing sewer pipes.
When sewer equipment comes in disrepair, it is repaired using technical sulfur. What is the mechanism of its action? The material is pre-melted in the electric furnace at a temperature of 130-135 ° C, and then poured it into the socket. Unfortunately, the repair may be poorly, if you failed to fill it simultaneously.
Avoid unpleasant consequences when working with gray will help adherence to special precautions, since the sealant is easily splashing, and careless appeal leads to the appearance of a chemical burn.
Insulation is performed using an oil bitumen. It is easy to clean the riser from the inside and outside, and after the work performed, the operational deadlines of the equipment are significantly increased and its effectiveness increases.
After the coating of the oil bitumen of the inner surface of the pipes, the friction coefficient of the liquid medium is reduced and the flow fluidity enclosed in the sewer pipe increases.
Epoxy resin is the most common material for. The joint is sealed, pouring the resin into the gap, and to obtain a strong result, it can be used hot and cold.
When working with portland cement, it is necessary to apply a mixture over the joint.
As for the work of software, the whole process requires the master of competent, suspended actions. After all, it is properly chosen tools and materials that make sealing in the shortest possible time.
You must purchase the following resources in advance:
Having reveaning the cause of the defect, the host turns to the sealing of the skin, using the following tools for work:
To work with silicone insulating material, you will need: a paint knife, a chisel, scraper, brackets, a glue gun, a brush, cutter, toilet paper, a spray gun, soap, a brush for spraying the solution. Such an approach to the choice of the necessary tools will allow working qualitatively and in a short time.
Sewage equipment, significantly worn, with numerous damage, is repaired using epoxy resin. Material is necessary to eliminate leaks when performing pipe repair.
Cell-cutters found after equipment inspection are close using a two-component adhesive composition. The mixture is prepared immediately before use, observing the manufacturer's recommendations.
A detailed examination shows that eliminating the flow is fairly easy, if applied to seal epoxy resin. The composition is used in combination with the hardener, and the ratio of components for the formation of the working mixture is 1: 2 or 1: 1.
The polymerization reaction proceeds much faster with increasing temperature by 10˚ C. The sealing of the resulting cracks is rather durable, since the epoxy composition has a minimal shrinkage, highly resistant to the action of adverse factors, stable physicomechanical characteristics.
The epoxy glue is obtained by mixing the resin and hardener in the proportion of 1:10, and distilled water is used for the formation of the composition with a water-fused resin.
Thus, observing, you can qualitatively carry out work related to the repair and planned replacement of equipment.
The sewer system that does not proceed, it is considered reliable. Therefore, good sealing of sewer pipes at home or in the apartment is a guarantee of the lack of trouble in the future.
The age of the sewage system, its wear (for example, pig-iron pipes in the risers of high-rise buildings), outdated materials, of course, can give to flow due to limitations and demand complete replacement. However, as practice shows, when operating the most vulnerable place, that when laying new, that when repairing old communications and plum systems, their connections are places. And the question remains than to seal the sewer pipes at the joints.
Earlier, linen winding or gypsum bandage and oil paint were used to seal cast-iron pipes in the risers and basements of houses and the apartment. But today in construction stores there are a lot of modern materials, sealants, to choose which it is necessary to deal with their prescriptions and properties, applies to draining systems.
For your information! Simple in use Modern materials allow you to perform all the work with your own hands, including waterproofing and sealing.
Self-adhesive tape - modern material for sealing joints in sewage system. It is a white film wrapped on a spool, has a different width.
Tip! To create a hermetic connection with a tape on the street, at the site of the scene, close the joints of the sewer pipes with sunscreen material.
Self-adhesive tape Experienced masters and builders are used not only to seal the joints of sewers. It is often used when working with fittings and various shaped elements.
To perform working qualitatively, you must first prepare pipes. They are thoroughly cleaned from dust layers, dirt, etc., and dried well. Covered with a layer of primer and dried again. After the surface prepared you can stick the tape.
The tape is wound around the desired area with a spiral with a half-trash, for greater tightness. After that, you can wind the second layer, in the same way. Pipe sealing!
Note! It is necessary to ensure that the winding process is not formed. Even small can reduce the tightness of the winding to zero.
Self-adhesive tape is well suited for processing joint joint joints, but this material is not always applicable in construction. There are other materials and substances capable of ensuring the tightness of the sewage system.
Silicone sealants are substances that are frozen when contacting air and have excellent sealing. Applied directly to the area requiring processing.
Sealants can be manufactured from a combination of various source materials. One of the most popular is silicone (or siloxane) consisting of silicone rubber and additives that increase the strength and adhesion of the material. To accelerate the polymerization of the substance, various vulcanizing impurities are used. As a result, it turns out similar to a rubber elastic material with excellent sealing properties and a wide range of applications.
Depending on which the hardening holder is used in the material, silicone sealants for plastic rip are divided into two types: acid and neutral. Acid sealants have limitations in the application and the cost is somewhat lower than those of neutral.
Sealants belonging to the class neutral are suitable for any surfaces and give excellent indicators in the bundle of various surfaces (for example, joints of metal and plastic sewage pipes).
Silicone sealants are enclosed in devices called mounting pistols. In the absence of this device, or the impossibility of its use, you can use the hammer handle, acting on the principle of the piston, pressing the bottom of the tube. Thus, dosing the extrusion of the required amount of material from the package, the necessary work is carried out.
Sealing of sewage systems in modern construction conditions is carried out by other types of materials. Often, the wizard is used epoxy resin, asphalt mastic, resin strands, hemp ropes and technical sulfur.
Most often, when working at home, epoxy resin is used. To rejugate this material, polyethylene polyamine for cold screwdrive is used, and maleic anhydride - for hot. But others can be used. The proportion of the combination may vary and average varies from 10: 1 to 5: 1.
Technical sulfur is used to seal sealing sewage. For this, it is crushed, heats up to a suitable plastic state and poured directly to the inner surface of the joints of the release tubes. This compound is made from Portland cement, in this case you need to prepare a solution.
For working with ceramics and cast iron, a scenar sawmed kneon rope is well suited. And the pouring from the oil bitumen and asphalt mastic well seals the joints in ceramic pipes.
To connect cast iron pipes, another pipe is inserted into the socket of one pipe, and the junction is sealed with the selected material. Experienced masters are carried out, as a rule, according to this technology:
For your information! Linen pass can be replaced by a hemp treated by a resin.
For your information! To create a mixture, if necessary, cement can be used in combination with asbestos fiber, in combination 2: 1, respectively. And before the fill in the pipe in the mixture, some water is added.
All the above materials can be replaced with silicone sealant, which is simply poured into the free space between the pipes of the riser. And for protection from too fast drying of this type of sealant, the place of application is covered with polyethylene or a damp cloth.
When repairing the old sewage in the house or apartment, the situation is very often occurring when it is necessary to docile new plastic pipes with old - cast-iron. And the question arises than and how to sewer the sewer pipe correctly.
For this you need:
If you adhere to technology and choose high-quality material to create a solid and sealed connection of the sewage system, it will be a good back for the future, preventer from the troubles associated with the sewage leakage. In our video you can see how the sealing and waterproofing of the sewage pipes are performed with their own hands.
