Sindrain is a high drainage capacity mat, consisting of a three-dimensional structure of polymeric monofilaments.

The materials performs 4 actions:

• it mechanically protects the sheath during the step of backfilling and throughout the life of the work;
• it filters the water from the ground to avoid the clogging of the drainage section;
• it drains and conveys water from the ground, eliminating the hydrostatic pressure;
• it constitutes an air knife in top surface of the structure, contributing to the thermal insulation.

Sindrain prevents water infiltration and formation of molds and moisture in basements.
