CONT: Geomembranes ... Reinforced bituminous membranes are built up from different elements, each with its own specific function, either in the production process or in use. In most cases, the basis of the reinforced membrane is a substrate of polyamide fabric or polyester membrane, soaked in a bituminous mixture. Depending on the production process used, it is possible to include a glass membrane and/or a polyester film either as a substrate or as a filler. The polyester film also acts as a barrier to the penetration of plants and roots through the membrane.
