Terrabase Addagrid
Description

Terrabase Addagrid is a geonet made by three sets of overlaid intersecting strands. The inner strands are thicker and heavier to provide high compressive resistance and transmissivity. The intersecting strands form overlaid sets of continuous deep channels which provide high flow capacity. They are made from extrusion of High Density Polyethylene (HDPE). For use as part of the Terrabase Resin Bound Surfacing System.
