EnviroFix – A proudly South African manufactured GCL (geosynthetic clay liner) for lining water and waste containment sites. EnviroFix ® is produced by needle punching a uniform layer of sodium bentonite between two layers of geotextile. Using a proprietary heat treating process – Thermal Lock™ – the needle punched fibers are modified and more permanently locked into place. EnviroFix ® has combined properties of low permeability and high internal shear strength making it a versatile hydraulic barrier.
