Bituminous geomembranes
High density polyethylene (HDPE) geomembranes are so commonly discussed that one might get the impression other geomembranes do not exist. However, there are other well-established geomembranes too: linear low density polyethylene (LLDPE), polyvinyl chloride (PVC) and polypropylene (PP) to name a few. Each of these materials possesses various formulations, unique mechanical properties and diverse project applicability. Of the many remaining membrane options, bituminous geomembranes are ones about which one hears little. Bituminous geomembranes have what could be seen as an unusual construction, so far as geomembranes go. Outwardly, they might appear similar to composites (e.g., geotextile bonded to netting). A basic bituminous geomembrane consists of a geotextile which is impregnated with a filled bitumen. The filled bitumen provides waterproofing, chemical resistance, flexibility and longevity characteristics. The nonwoven geotextile provides the mechanical characteristics of the membrane: tensile strength, puncture resistance, and more.
