Tri-Planar Geonetis is a synthetic drainage materials manufactured from a specific grade of high-density polyethylene (HDPE) resin, designed to transmit fluids and gasses uniformly under many field conditions.

Tri-planar products consist of centralized middle HDPE ribs that provide channelized flow, and diagonally placed top and bottom strands that minimize geotextile intrusion. The void maintaining core structure provides higher transmissivity than bi-planar products.
