TerraTex® High Performance

TerraTex® High Performance Stabilization Geotextiles (HPG) provide enhanced separation, filtration, reinforcement. and even wicking functions for a wide range of soil conditions. These unique products offer excellent performance in wet subgrade conditions as well as increased frictional interaction with roadway base aggregate.

TerraTex® geotextiles are made up of high tenacity polypropylene yarns. These yarns are woven to form a stable and durable network such that the yarns retain their relative position. They are non-biodegradable and resistant to most soil chemicals, acids, and alkali with a pH range of 3 to 12. Unless noted otherwise, all values are minimum average roll values (MARV).
