Separation and Stabilization

TerraTex® woven geotextiles are designed to be used between subgrade and granular fill. They are available to meet various classifications of AASHTO M288.

TerraTex® woven 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).
