Polypropylene Geomembrane
Reinforced polypropylene provides a versatile flexible geomembrane liner. The unique three ply construction with a combination of custom fabric reinforcement encapsulated by extruded high performance polypropylene provides a strong, highly chemical resistant liner.
The chemically inert polymer is modified to provide many specialized properties that include excellent flexibility, low thermal coefficient of expansion and contraction, outstanding dimensional stability, wide temperature range for excellent seaming and good chemical resistance in exposed liner applications. All factory and field seams are thermally welded.
