Geonet is a synthetic drainage material manufactured from the highest quality high-density polyethylene (HDPE) structures, also called "geospacers" . Geonet   consist of centralized HDPE strands which the maintaining core structures provide higher transmissvity than bi-planar geonet.  Geonet are generally designed to transmit fluids and gasses. There are two kinds of geonet in GeofanTex Geosynthetics, which are bi-planer and tri-planar Geogrids.
