Geomembrane

A ProFlex geomembrane is ideal for most applications and major benefits to installation are provided by lower coefficient of thermal expansion and a wide temperature-welding window.

ProFlex is a propylene/ethylene copolymer geomembrane produced from a resin formulation designed to provide quality geomembrane with excellent flexibility, and improved elasticity and resistance to puncture. These properties assure maximum multiaxial elongation to accommodate differential settlement. ProFlex is ideal for most geomembrane applications and major benefits to installation are provided by lower coefficient of thermal expansion and a wide temperature-welding window.

Geotextile

A mechanically bonded nonwoven geotextile that demonstrates a high tensile and CBR to offer an element of protectionin addition to the standard requirements of separation and filtration. A heavier weight geotextile with both mechanical and hydraulic properties to address the more demanding end of the separation/filtration market and start of the membrane protection market.In applications such as attenuation SUDS systems or small pond/lagoon applications, it offers effective protection of the impermeable liner.
