Geomembranes are flexible polymeric sheets mainly employed as liquid &/or vapour barriers. Polymeric geomembranes are designed as relatively impermeable liners for use in a variety of containment situations (e.g. to contain water, process fluids, leachates, mine liquors and contaminated industrial liquid effluents), in applicatins where natural clay or other containment options are not possible or visible. Base liners  are typically HDPE because of its inherently good chemical resistance and strength, whereas the covers are generally LLDPE, VLDPE or fPP since they are more flexible than HDPE and hence conform better to the underlying decomposing waste and are better able to tolerate the strains associated with waste settlement. Another geomembrane is produced by different polymeric materials such PVC, EPDM, CSPE, fPP and etc.  each type of geomembrane material has different characterstics that affect its installation procedures, durability, lifespan and overall performance. It is therefore necessary to match the project performance criteria with the right combination of properties of particular geomembrane. Geomembrane materials are generally selected for their overall performance in key areas of chemical resistance, mechanical properties (elastic modulus, yield strength, puncture/tear resistance), weathering resistance, product life expectancy, installation factors and cost effectiveness. The properties of polymeric geomembranes are determined mainly by their polymer structure, weight and the crystalinity.

Booman is producing geomembrane based on HDPE & LLDPE with high quality.
