Geomembranes can be made from a variety of materials or a blend of materials. The most common examples include high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), chlorosulfonated polyethylene (CSPE), ethylene propylene diene monomer (EPDM), and polypropylene (PP).
Each material offers unique properties and characteristics, such as flexibility, chemical resistance, and durability, to suit different applications and environmental conditions. Additionally, geomembranes can be reinforced with fabric or other additives to enhance strength and performance.
