Polypropylene is a rugged, thermoplastic polymer that is resistant to many chemicals, solvents, bases, and acids, making it the perfect liner for a variety of exposed and covered applications.

Designed with exceptional tensile strength and excellent environmental stress cracking resistance, LCSI’s polypropylene geomembrane liners resist punctures and remain unaffected by UV, ozone, and soil bacteria. Our standard product is reinforced with a scrim inserted between the top and bottom plies, but it is also available in a non-reinforced material.
