Materials for sealing constructions

When mounting unacceptably following:

  • leaks inside (ingress of groundwater into the sewer system);
  • leaking inside.

Sealing of sewage
Applied Materials:

  • sealants of silicone;
  • tape for sealing;
  • resin tow and mortar;
  • other means by which the sealing is carried out sanitation.

Sealants silicone

Materials for sealing
Silicone sealant for sewer
sealants based on silicone are a set of various substances, which subsequently have high levels of insulation.Excellent adhesion to surfaces of silicone sealant provides a possibility to exclude pre-treatment with primers.
Depending on the curing agent used in the production share:

  • neutral (suitable in most cases);
  • acid (applies only to not react with acidic compounds).

Using sealants based on silicone to seal the sewer pipes of the following:

  • of plastic;
  • metal.

curing process takes the form of a mixture of substances whose properties are similar to rubber.Moisture in the air, take part in the curing process.
Sealants based on silicone
When using sealant based on silicone use fastening tool.If there is no hand, this operation can easily spend a hammer handle, inserting the back side of the container with silicone and gradually pressing, if the piston.

Application harness resin and grout

classic method has sealing joints of sewer pipes using resin Crimping wiring to 2/3 the depth of the socket, then fill with 1/3 of the cement slurry.Use necessary 300K brand cement and higher observing cement to water ratio of 9: 1.
Crimping seal
Crimping sealing procedure is very tedious and time consuming, may it be changed to use a cement mixture, having the properties of water resistance and expansion, as well as rapid solidification.Self-sealing with the extension.

sealing tape

Self-adhesive tapes
One of the newest pipe sealants are self-adhesive tape.They are specially designed for sealing and also have anti-corrosion properties.It is possible to note the following positive qualities:

  • used to protect various types of structures, possessing anti-corrosion and dielectric properties.Also may be applied to seal in the linear sections of sewer pipe.
  • Easy to use and high performance.
  • Good operating performance sealing films, due to the high strength of the foundations of polyethylene.
  • different areas of use, not only in the areas of joints, and turning corners, bends and tapping.

Sealing tape sewerage
When sewer sealing tape is carried out, the work must be performed in the following sequence:

  • Before applying the tape is necessary to prepare the area of ​​application (dry, clean and dust-free)
  • To eliminate the appearance of fine lines and wrinkles, it is necessary to ensure constant tension.
  • to create two layers of film over the entire surface, it is necessary to apply 50% of the tape in a spiral overlapping.

tapes can not tolerate direct exposure to UV radiation.On - the need to provide an additional protective layer for this film, if the structure is exposed to sunlight.

Other sealing means

  1. Tar strand jute or hemp rope - used for sewer pipe made of ceramics and iron, when terminating sockets.
  2. Technical sulfur - used for sealing joints sockets cast-iron sewer pipes.Det necessary to grind, heated to melting point and fill in the gap junction.
  3. mastic asphalt and petroleum bitumen - is used for filling and sealing joints bells of sewer pipes made of ceramics.
  4. epoxy resin - is the most common means for connecting sewer pipes.
  5. Portland cement - one of the components of the sealing mixture.Used in mixtures with asbestos Crimping iron bells of sewer pipes.

above listed materials have high reliability.On this major nuance is a sound approach to the process, in order to avoid leaks afterwards.
