Tenax TDP geocomposites result from the combination of a cuspated geonet and a geotextile. Their three-dimensional structure is designed to ensure water flow in every direction, therefore Tenax TDP are comprehensive drainage geocomposites.
The lamination with one or two geotextiles (filtration and protection) offers a complete “filtration-drainage-protection” system.
The high thickness of the cuspated drainage geonet provides a high compressive strength: Tenax TDP geocomposites ensure high level of flow rate even under high loads (500 kPa) or with very low slopes.
The draining net of Tenax TDP is available in different thicknesses, and the product can be laminated with one or two geotextiles (TDP/1 or TDP/2).
