 The geotextile is specially designed for covering of the DRAINMAX tunnel. The propylene filter fabric is a particularly robust geotextile that can withstand heavy loads. The pollutants are retained, due to its good separation effect, in front of the infiltration system and it provides at the same time exceptional long-term water permeability. The certified geotextile for approved DRAINMAX Tunnel is compliant with DIBT.
