The lift pit liner is a 1mm propylene/ethylene co-polymer geomembrane. Produced from a resin formulation designed to provide a premium quality geomembrane, which exhibits excellent flexibility, improved elasticity and resistance to puncture. These properties assure maximum multi-axial elongation to accommodate differential settlement. Polypropylene is ideal for geomembrane applications, and major benefits to installation are provided by a lower coefficient of thermal expansion and a wide temperature-welding window. Heat welding produces a homogenous membrane being totally impervious to water ingress. The product lends itself to applications where high/variable water tables, standing water and water creating hydrostatic pressure areas are in evidence.
