TerraTex® Filtration

Filtration products are typically monofilament in construction, which provides enhanced hydraulic performance, enabling water to flow in two directions with resistance to clogging in shoreline applications.

TerraTex® geotextiles are made up of monofilament 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).
