The geo-membranes are used for geo-technical engineering solutions in fluid containment requirements. The growing concern over contamination of valuable water resources and fluid migration to subsurface soils and groundwater has results in the increasing awareness of, interest in, and demand for geo-membranes made from polymeric materials to replace more traditional porous liners such as concrete, clays and soils. The primary function of geo-membranes is to provide impermeable liquid or vapour barriers. They are usually made from continuous polymeric sheets that are very flexible. Continuous development is resulting in new product advances and new manufacturing technologies.
