Coletanche® is a unique bituminous based waterproof geomembrane. Manufactured by Axter, a wide range of products ensure that all civil engineering needs can be met, including resistance to different chemicals and sources of pollution etc.

In 2001, it is the beginning of modernisation work of the production tool on the Courchelettes Factory: the installations and industrial processes are completely refurbished and bring the production capacity to more than 30 million m²/year; this leads the company in 2006 to further expansion work and to the installation of a new line intended for the manufacture of COLETANCHE geomembranes. The latter are directly aimed at civil engineering and major works thanks to its unique design: its width of 5.1m.
