A waterproof coating that runs along the perimeter of the house with a slope away from it is called a blind area and serves as a foundation protection from rain and meltwater.

The destruction of the foundation occurs due to the negative air temperature in winter and the presence of water or moisture in the ground.  The heaving of the soil is dangerous due to uneven lateral pressure on the foundation, which can lead to the distortion of the building.  

Usually blind areas are made of monolithic concrete using unnecessary building materials, or materials of poor quality. The service life of such a blind area is small, since it does not perform its main function - the protection of the foundation. The blind area of the house does not involve any heavy loads and is designed for ordinary pedestrian traffic. Therefore, for the arrangement of the blind area system, it is enough to use a spike-shaped membrane with a density of 400 g / m.kv with geotextile.

Outdated materials are being replaced by modern and higher-quality ones. The use of a more mobile, elastic and waterproof material, such as a profiled spiked membrane, can ensure the correct and long-lasting operation of the waterproofing of the foundation and the removal of ground, meltwater from the foundation of the building.

Profiled spike-shaped membrane with geotextile in the construction of the blind area perfectly copes with the role of waterproofing. This design of the blind area is more technologically advanced during installation. Its installation is carried out in all weather conditions. The spike with geotextile does not crack, does not decompose in the ground, is not susceptible to germination of plant roots. The composition of the geomembrane includes stabilizing additives that make the geomembrane resistant to low temperatures, ultraviolet radiation and aggressive effects of various chemicals. Such a membrane is made of high-density polyethylene (HDPE)

The main advantages of the spiked membrane SNTDRAIN DL8 GEO 450 are biological resistance against fungi, bacteria, germination of plant roots;  UV resistance; easy and quick installation - the surface for installation does not require special preparation. The material does not decompose, does not rot, does not oxidize.
