Teranap GTX

Prefabricated Bituminous Geomembrane


Teranap GTX is a bituminous geomembrane that has been closely bonded to a puncture resistant geotextile which enhances the mechanical performance making it the most robust membrane in the industry.  The geotextile face improves frictional resistance on the underlying substrate.  This innovative membrane allows new methods of application of layered concrete over the Teranap GTX membrane, including cast-in-place concrete and shotcrete (fiber-reinforced concrete). The underside is covered with a polyester film.


Because of its enhanced mechanical properties, Teranap GTX can be successfully applied on canals and dams for both new and rehabilitation projects. Repairs of accidental damage to Teranap GTX can be easily carried out by the maintenance staff.


Main Uses: Waterproofing of sloped areas of canals, reservoirs, dams (for new or rehabilitation work).
