Tri-Planar Geonets and Geocomposites
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.
GSE Tri-Planar Geonets are synthetic drainage materials manufactured from the highest quality high-density polyethylene (HDPE) resin. They are designed to transmit fluids and gasses uniformly under many field conditions.
Tri-Planar Geocomposites consist of a geonet heat bonded with a nonwoven needle-punched geotextile, and are designed to provide drainage filtration to keep silt and soil particles from clogging the flow or to increase the friction characteristics.
