Geomembrane
Request a Quote
Our geomembrane is meticulously crafted as per ASTM standards, and it is mainly made from polymer resin (high density polyethylene), thus imparting some outstanding properties to this synthetic flexible membrane, such as low permeability, good corrosion resistance, remarkable UV resistance, etc.
Application
Due to its superior features, our impermeable geomembrane liner offers efficient and cost-effective lining and covering solutions for reservoirs, mining factories, solid waste landfills, etc.
