TECHDRAIN- Drainage Composite

TECHDRAIN is a drainage composite obtained by coupling a two or three-dimensional core of high-density polyethylene polymer and covered by nonwoven geotextile. The drainage core comprises two or three sets of parallel overlaid ribs integrally connected to form a rhomboidal shape, providing high resistance to compressive strength. Filter fabric (PP) is placed on one or both sides of the drainage core to prevent clogging by filtering out fine particles from the surrounding soil.
