The Corden EPS hydrocarbon membrane is constructed from high density polyethylene that is produced from a proprietary virgin polyethylene resin that is designed specifically for flexible geomembrane applications.

It offers oustanding chemical and mechanical resistance properties as well as environmental stress crack resistance, dimensional stability and thermal aging characteristics.

The Corden EPS hydrocarbon membrane is also resistant to UV radiation, which makes it suitable for use in exposed conditions.

A textured version of the membrane is available that can be built into the masonry structure to avoid transference to a DPC.
