Geocomposite-membrane™is an integral part of the StrataCell™ system, whose primary function is to prevent the surface above the StrataCell™ construction from subsiding. The membrane also prevents external soil and particles from mixing with soil in a tree pit.

The high breaking load of the Geocomposite-membrane™ is achieved by using non-woven, geo-textile and vulcanised polypropylene reinforcement.

This combination of materials results in a robust and resistant membrane which is light weight and easy to work with.

The Geocomposite-membrane™ should cover both the surface and sides of a finished StrataCell™ construction.
