Hdpe double smooth geosynthetic membrane is consist by 97.5% high density polyethylene material and about 2.5% carbon black and other material.
Our Anti-seepage HDPE geomembrana is manufactured via triple co-extrusion technique by the most advanced automatic equipment. All the productions are manufactured according to US GRI standards and ASTM, complete specifications with superior quality. The width can reach 8m. Anti-seepage HDPE geomembrane IS far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation than traditional concrete, asphalt and compacted clay.
