Terre Hill Composites, Inc. (THC)

More effective in resisting corrosion than competing trenchless lining solutions. Proven superior in acid resistance to other technologies in tests conducted by the Sanitation District of Los Angeles County, Multiplexx PVCP Liners from Terre Hill Composites add years of utility to aging sewer structures while saving you tens of thousands of dollars through rehabilitation rather than reconstruction. Prefabricated for each application, their unique and patented design employs an inward-facing layer of PVC for protection against sewer-gas corrosion and ground-water infiltration. Multiplexx Liners are then embedded with epoxy-saturated resin, backed with fiberglass, pressure installed and cured-in-place to form a chemically-stable, reinforced structure.
