The construction of basins designed to hold liquids or polluted industrial effluents is increasing, while groundwater protection has become a priority in Europe and in the rest of the world. This originated in Europe and in France with the water law. Thanks to its natural sealing performance and resistance to common chemical and biological pollutants, the COLETANCHE® geomembrane is widely used to seal leaching basins and polluted water retention basins in the mining of agri-food, industrial, etc. By its nature, COLETANCHE effectively ensures its essential function for waterproofing and offers many other advantages:
High Resistance to U.V
The nature of the elastomeric binder (SBS) and the sanded top surface of COLETANCHE allows for use in exposed conditions, without any special protection against ultraviolet rays. By avoiding the addition of a protective layer, the use of the COLETANCHE® geomembrane saves on storage volume.
The binder based on bitumen-SBS is stable in water environments, sea water, brines and our technical team is able to meet your specific needs*. Experience shows excellent performance of COLETANCHE® for the following projects: saltwater storage (salt and potash mines), agri-food, sugar plants, copper and nickel mining leachates, etc.
* A detailed study is required if the pH effluent is less than or equal to 2 and greater than or equal to 13
Compatibility with Asphalt
The nature of COLETANCHE® makes it especially compatible with asphalt or other bituminous concrete*. These materials can be used as membrane protection layers to enable cleaning of basins, access to machines and truck works. The waterproofing seal remains continuous.
* A fiber reinforced concrete protection is also possible

Fast and Reliable Implementation and Maintenance
The surface weight* of COLETANCHE® and its tolerance to temperatures between -40 °C and 40 °C (-40 and 104° F) allows for implementation in extreme weather conditions (wind, rain, cold). Thus, avoiding site interruptions, deadlines are met and the works are quickly underway.
*A surface weight between 4.2 and 6.4 kg / m² (124 to 189 oz/yd2) enables for COLETANCHE® to resist movement by wind. Intermediate anchor techniques enables use in very windy areas
