Velkoseal® / Enviromat
Enviromat is a Geosynthetic Clay Liner (GCL) made from quality polypropylene Geotextiles and premium grade natural sodium bentonite. Enviromat is fiber-reinforced by needle-punching the composite across the entire length and width of the product. The high tenacity fibers are then thermally locked to ensure high long term shear strength.
