2D geonet drainage system

Two-Dimension Drainage Geonet with high density polyethylene (HDPE) as raw materials, through special process, the two root rib in a certain distance and Angle arrangement, staggered at the intersection of double rib form drainage channel. Has high tensile strength and compressive strength, rib between a drainage channel in the higher load is out of shape not easily, it can prevent geotextile embedded geotextile net core, ensure drainage unblocked.
