When installing modern heating systems and pouring concrete bases, it is critically important to take into account the physical properties of the materials. Damper tape is that very unnoticeable but indispensable element that protects the floor covering from cracking and deformation. The SANSTORE online store offers high-quality construction materials for finishing and preparatory work, which guarantee an impeccable result.
Concrete, like most building materials, tends to expand when the temperature changes. This issue is particularly acute when installing water or electric underfloor heating. To compensate for this linear expansion and prevent excessive pressure of concrete on the walls, a special damper tape is used.
It performs several essential functions at once:
- Absorption: takes on the internal stress of the concrete slab.
- Thermal insulation: reduces heat loss through the floor-to-wall joints.
- Sound insulation: dampens structural noise and vibrations, preventing them from being transmitted to the walls of the building.
Varieties and Features of the Material
In the modern market, this material can be found under different names depending on the project documentation or the habits of the craftsman. For example, expansion joint tape is often used not only around the perimeter of the room, but also to divide large pouring areas into technological sectors. This helps to avoid the uncontrolled appearance of cracks on the monolithic surface.
High-quality expansion tape is usually made of foamed polyethylene. This material has a closed-cell structure, thanks to which it does not absorb moisture from the cement mortar, does not rot, and maintains elasticity for decades. Many models are equipped with a protective polyethylene "apron" that seals the joint between the wall and the waterproofing.
How to Properly Install Floor Screed Tape?
The installation process is quite simple but requires accuracy. The material is rolled out along the entire perimeter of the room before starting to pour the mortar. If the area of the room exceeds 30 square meters or the length of one of the walls is more than 8 meters, intermediate joints must be arranged, where additional compensation tape for the screed is laid.
Fixing the tape to the walls can be done using liquid nails, a construction stapler, or a self-adhesive layer provided on the back of premium models. The height of the roll is selected so that the edge of the material is slightly higher than the expected level of the finished flooring. Excess material is easily cut off with a utility knife after laying tiles, laminate, or linoleum.
