Geotech fabric (geotextile fabric or geo-fabric) can be used for a variety of applications such as french drains, drain fields, erosion control, separation and stabilization, and more. The fabric, made from a polypropylene blend, is needle punched to provide water permeability. This geotextile material is specially formulated to resist ultraviolet light deterioration and is inert to commonly encountered soil chemicals. The fabric will not rot or mildew, is non-biodegradable, and is resistant to damage from insects and rodents. (For bulk orders only: please note rolls are 360 ft. long and there are 600 sq. yrds./roll).
