Spec InterpretationUS 400
Woven Stablization/Separation
US 400 is a woven geotextile made of 100% polypropylene slit film yarns that are "white" or natural in color. UV Stabilizers are added. US 400 resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. Polypropylene is stable within a pH range of 2 to 13. US 400 will satisfy the requirements as outlined in PA DOT 4B Stabilization applications and meets the following M.A.R.V. values except where noted:
