Geomembranes are manufactured from several types of high-performance polymers, each designed to meet specific engineering and environmental requirements. The most commonly used materials include High-Density Polyethylene (HDPE), Linear Low-Density Polyethylene (LDPE), Polyvinyl Chloride (PVC), Ethylene Propylene Diene Monomer (EPDM), and Polypropylene (PP). Among these, HDPE geomembranes are the most widely used because they provide outstanding chemical resistance, high tensile strength, excellent puncture resistance, and exceptional durability. LDPE geomembranes offer greater flexibility and elongation, making them suitable for projects requiring installation over uneven or irregular surfaces. PVC geomembranes provide excellent flexibility and ease of installation in decorative ponds, water features, and landscaping applications. EPDM liners are known for superior flexibility and resistance to weathering, while polypropylene geomembranes combine chemical resistance with excellent mechanical performance. Most geomembranes also contain ultraviolet (UV) stabilizers, antioxidants, and carbon black additives that protect against sunlight exposure and environmental degradation, ensuring long-term service life even in harsh outdoor conditions.
