Civil Nonwovens

TerraTex® nonwovens meet various classifications of AASHTO M288 for subsurface drainage, separation, stabilization, and erosion control.

TerraTex® nonwoven geotextiles are made up of polypropylene fibers. These fibers are needled to form a stable and durable network such that the fibers 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).
