Bituminous Geomembrane (BGM) liners (Coletanche) are an extremely versatile flame-resistant containment solution. Highly resistant to punctures and tearing, they're also highly flexible and can hold a friction angle of 34 degrees. They are compatible with most materials, which makes them safe for direct installation on most soil types.

Capable of direct cover by vegetation, poured concrete and hot mix asphalt -- the temperature is not a concern
Flexibility and dimensional stability provide permanent contact with the substrate and make it ideal for differential settlement
Resistance to chemicals (including VOCs), biological agents and oxidation
UV resistance means it can be left exposed indefinitely
Self-healing bitumen seals around punctures and penetrations
Installation on 3” compacted subgrade significantly reduces site preparation costs
High surface mass allows installation in strong wind or underwater and saves on ballasting costs & effort
Easy to weld and bond and can be welded to other membranes (HDPE, LLDPE, Polypropylene or PVC), other types of BGM, concrete or steel
