Sealing the entrances of communications into the building is an important stage of construction work aimed at preventing the penetration of external influences into the building.

This process not only prevents possible damage from precipitation, groundwater, parasites and rodents, but also maintains the reliability and safety of the structure.

Here are some key points of the technology of sealing the inputs of communications into the building:

Selection of materials:

• Sealing must be carried out using high-quality and durable materials.
• The materials must have good adhesive properties to various building materials such as metal, concrete and plastic.
• Resistance to aggressive media, including wastewater, chemicals and alkaline substances, is also an important criterion.

Requirements for materials:

• Materials must have high elasticity to compensate for possible deformations or movements in building structures.
• Resistance to temperature fluctuations during operation is an important aspect for the durability of sealing.

Sealing process:

• The process begins with cutting out the grooves around the embedded sleeve, followed by processing the contacting surfaces.
• The sleeve is wrapped with a special swelling cord, such as bentonite cord Hydrostop Sanpol or acrylic cord Hydroflex.
• The concrete surfaces around the sleeve are pre-wetted with water.
• The free space is filled with a repair non-shrinkable mixture.
• The final stage is the application of penetrating waterproofing to the concrete surface around the communication entry points.

Compliance with technological standards:

• Sealing must be carried out in strict accordance with technological standards and procedures.

Effective sealing of communication inputs helps to maintain the durability of the building, prevent the formation of dampness and fungus, and also ensures the preservation of the microclimate inside the building.
