COLETANCHE Bituminous Waterproofing Geomembrane

BGM liners are used for waterproofing civil engineer and mining structures (i.e. mine tailing dams, mine water process ponds, heap leach pads, capping of contaminated land, erosion protection, canal and reservoir lining) COLETANCHE is a robust bituminous geomembrane (BGM) that does not require a protective cover such as soil or geotextile and can stay exposed to UV. It is very robust and may be safely covered by large stones without being damaged. Thanks to its remarkable dimensional stability it is not affected by temperature changes avoinding the formation of wrinkles. Its high surface mass prevents wind uplift and permits the membrane to be sealed under water.
