TerraTex® EP-404

TerraTex® EP-404 is a woven monofilament geotextile made up of polypropylene filaments. These filaments are woven to form a stable and durable network such that the filaments retain their relative position. It is non-biodegradable and resistant to most soil chemicals, acids, and alkali with a pH range of 3 to 12. TerraTex® EP-404 is manufactured to meet or exceed the following minimum average roll values:
