Sealing of communication inputs

What does the waterproofing of a building consist of? Waterproof concrete, waterproofing of foundations, walls, roofs, sealing joints. All this is correct, but there is something else that is very often forgotten, and this is the sealing of the communication inputs.

Without proper waterproofing of pipe entries, cables, vent channels and other communications, you will not have a completely dry building. Such places are considered very vulnerable and require increased attention when performing work. Improper arrangement of them leads to leaks, dampness, mold and, as a result, to the destruction of the integrity of the structure.

How to properly seal the inputs of communications?

First of all, it is necessary to understand that the sealing of the inputs is a separate independent stage of waterproofing. It requires strict compliance with the technological order and the selection of the most reliable materials with a long service life.

When choosing materials, the following requirements must be taken into account:

• Good adhesion to the material (plastic, concrete, metal)
• High elasticity
• Resistance to tears, deformations, vibrations
• Resistance to temperature changes during operation
• Resistance to aggressive media (alkalis, chemicals, sewage, etc.)

The technology of sealing the inputs:

• Around the embedded sleeve it is necessary to make a strobe about 7.5 cm x 2.5 cm.
• Clean and dust off all contact surfaces.
• Wrap the sleeve with a swelling cord (bentonite Hydrostop Sanpol or acrylic Hydroflex).
• Moisten the concrete surface around the sleeve.
• Fill the space with a non-shrink repair compound Teknomer 300EX.
• Apply Teknomer 100 penetrating waterproofing to the concrete surface around.
