PVC Geomembrane

PVC geomembrane is a polyvinyl chloride liner known for its high flexibility and ease of installation. It adapts readily to complex geometries, irregular substrates and detailed junctions, making it a practical choice for building foundations, tunnels, ponds and roof waterproofing applications. Signal layer options are available for visual leak detection and quality assurance. UV resistant variants are available for exposed applications. Plant root resistant, suitable for green roof and landscaping systems.

HDPE Geomembrane

HDPE geomembrane is a high-density polyethylene liner engineered for demanding applications where chemical resistance, mechanical strength and long-term UV stability are critical. Manufactured with antioxidants and carbon black, it performs reliably in aggressive chemical environments including landfills, mine tailings, acid pools, tank farms and wastewater treatment facilities. Available in smooth, single-side textured and double-side textured finishes. Large roll sizes enable efficient installation across large project areas.

VLDPE Geomembrane

VLDPE geomembrane is a very low density polyethylene liner offering exceptional flexibility and elongation for projects requiring adaptability to movement and complex shapes. Its highly flexible structure makes it well suited to tunnel waterproofing, irrigation channels, ponds, artificial lakes and underground structures including metro stations and curtain wall insulation. Textured variants are available for sloped applications where increased friction between the membrane and geotextile is required.
