Sealing the entrance of communications into the building

The inputs of communications into the building are potentially dangerous and weak points. Atmospheric precipitation, groundwater, parasites, small rodents, etc. can penetrate through them. As a result, dampness, fungus and mold form in the room. In addition, the strength of the load-bearing structures of the object may be damaged and the microclimate may be disturbed, which is why the safety of the building decreases. This can be avoided due to the high-quality sealing of the places of entry of communications with the help of special materials.

Sealing technology of communication inputs into the building

Any places where utilities and utilities are introduced into buildings must be sealed. The main locations of the inputs are most often the basement, foundation, ground floor, floors, walls and partitions.

To begin with, it should be understood that the sealing of the inputs is carried out as a separate stage of waterproofing work. Sealing must be carried out in strict accordance with technological standards, the procedure for choosing the most reliable and durable materials.

When choosing materials for sealing the entrances to the building, a number of important requirements that the composition should have should be taken into account:

• Good adhesive properties to materials such as metal, concrete and plastic
• Resistance to aggressive media (sewage, chemical and alkaline substances, etc.)
• Resistance to temperature changes during operation
• Increased elasticity

The sealing of the input of communications should be performed as follows:

• Around the embedded sleeve, you need to cut a hole in the wall, measuring about 7.5x2.5 cm
• Then all the touching surfaces are cleaned and dust-free
• After that, the sleeve must be wrapped with a swelling cord – an acrylic Hydroflex or a bentonite Sanpol Hydrostop is suitable for this
• The concrete surface surrounding the sleeve is pre-wetted with water
• Next, the free space is filled with a repair non-shrinkable mixture
• The final stage will be the application of penetrating waterproofing on the concrete surface around the points of entry of communication
