Mirafi Mirafi RS380i US Fabric Equivalent is US HT400

US HT400 is manufactured using high tenacity polypropylene yarns that are woven to form a dimensionally stable network, which allows the yarns to maintain their relative position. US HT400 resists ultraviolet deterioration, rotting, and biological degradation and is inert to commonly encountered soil chemicals. US HT400 meets the following M.A.R.V. values except where noted:

Mirafi RS380i is a revolutionary geotextile with orange identification yarns and super high-tenacity polypropylene filaments formed into an innovative weave to provide superior reinforcement strength and soil interaction integrated with high water flow and soil retention capabilities. TenCate Geosynthetics Americas Laboratories are accredited by Geosynthetic Accreditation Institute – Laboratory Accreditation Program (GAI-LAP).
