Joint Replacement Technology


Sealing of joints in the house consists of several steps, the quality of each of which depends on the quality of the final result. High-quality sealing expansion joints requires opening them.

Consider repair of joints of panels with opening step by step.

The described sealing of joints in panel houses is called "Warm Joint". Its main difference from the previously used is the application of a layer of heat protection foam in the base of the joint.

Such repair of joints in panel houses has passed many tests and has long been successfully used all over the world and by our specialists.

Sealing of joints in the house in stages:

1) Preparatory measures before carrying out the repair of joints. Conclude in the preparation of surfaces and include:

  • cleaning of surfaces from paint, dirt, peeling of panels;
  • Removal of old insulation, sealant;
  • expanding cracks.
  • Cleaning and sealing of joints in the houses is performed either manually or mechanically. The surfaces of interpanel joints shall be in dry condition before the beginning of works.

2) Filling of interpanel joints with thermally insulating polyurethane foam. During curing, the foam expands, filling the existing voids inside the joint.

3) Installation of insulation "Vilaterm". "Vilaterm" - insulation, which has the form of hollow tubes. It is widely used when repairing joints in panel houses. It is elastic, has a dense structure, very easy to work with.

Insulation is laid on the not yet frozen layer of foam. Insulation in diameter should be larger by 20-30% of the width of the interpanel joint.

"Vilaterm" is laid in the interpanel joint without tearing along the entire length, so that there is room to apply sealant over the insulation.

4) Final finishing sealing of joints with sealing mastic. This is the final stage of work on sealing the joints of panel houses or repairing the interpanel joints.

Sealing of external seams of the house at this stage is carried out with water-repellent sealant, which covers the already laid insulation.

At this stage, sealing of interpanel joints, i.e. repair of joints (or caulking of panel houses) is completed!

The temperature range for the work performed on sealing the joints between the panels of the house: from -10 ° C to +30 ° C. In addition, caulking of exterior house joints should not be carried out in the presence of precipitation: snow or rain, as the sealing of joints may not last long.
