Tenax TDP geocomposites are made from a combination of a cuspated geonet and a geotextile. Their three-dimensional structure is designed to ensure water drainage in all directions: Tenax TDP are therefore 360° draining geocomposites.
Lamination with one or two geotextiles (filtration and protection) offers a complete "filter-drain-protection" system.
The high thickness of the cuspidated drainage layer provides extremely high compressive strength: Tenax TDP guarantees high flow rates even under high loads (500 kPa) or on very low slopes.
