US 400 is a woven geotextile made of 100% polypropylene slit film yarns that are "white" or natural in color. UV Stabilizers are added. This product provides separation of the aggregate from the subgrade and has high tensile strength and modulus, adding reinforcement to the foundation soil. 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:
