Technodrain 6.2 - Thin and flexible double structure drainage - MatGeco

Technodrain 6.2 is a thin and flexible drainage geocomposite . It is thus made up of a membrane with a three-dimensional alveolar structure with a very high void index and covered on both sides with a non-woven geotextile.

Resistant up to 45 t/m², this drain is ideal for horizontal drainage under high pressure. It is also the solution for vertical drainage , ventilation and protection of your foundations , walls , tunnels , etc.

In addition, its double structure with high drainage power allows ventilation of the foundation and protection during backfilling while avoiding hydrostatic pressures .

Horizontal drainage under stabilized:

For an implementation of TechnoDrain 6.2 in horizontal drainage on a waterproofing, it will be necessary to unroll the geocomposite strips edge to edge and deploy the overflowing geotextiles on the adjacent panel. The stabilized sand serving as a laying bed for the paving or paving will then be carried out on the TechnoDrain 6.2. Its double structure will allow the water infiltrated through the paving to flow above but also below the membrane, thus avoiding stagnation of water on the waterproofing.

Vertical drainage for buried walls:

For vertical drainage, the TechnoDrain 6.2 will be implemented against the waterproof membrane before bringing the earth against the buried walls. Its double structure with high draining power allows ventilation of the foundations and protection during backfilling while reducing hydrostatic pressures. The water collected in the membrane will be brought into a drainage system located at the foot of the basement.
