Moisture Management

TerraTex® DriBase™ can reduce or help maintain the moisture content of subgrades and base courses, which improves resilient modulus and overall pavement performance. Moisture management geotextiles mitigate frost heave damage to pavements in frost-susceptible soils/regions. TerraTex® DriBase™ helps control the movement of water in roadways.

TerraTex® DriBase™ is a high-performance warp-knitted geotextile engineered to provide separation, filtration, stabilization, and moisture management in roadway applications. It is non-biodegradable and stabilized to resist degradation due to ultraviolet exposure, as well as commonly encountered soil chemicals, mildew, and insects. TerraTex® DriBase™ is manufactured to meet the values listed in the following table.

All values provided are intended for rapid comparison purposes, only. Please refer to a specific product’s Product Data Sheet (PDS) and the disclaimers therein for a detailed listing of all characteristics, associated definitions and values needed for structure design, specification compliance review and product submittal purposes. Please Download PDS for all information transfer, printing and submittal purposes.

Unless noted otherwise, all values are minimum average roll values (MARV)
