We, Shanghai Yingfan, are a professional manufacturer of geomembrane‑supported geosynthetic clay barriers (GCL) in China. Large‑quantity supply with competitive price is available. According to environmental regulations, landfill leachate must be collected and properly treated, otherwise groundwater contamination will trigger severe environmental and ecological risks. Lower hydraulic conductivity enables GCL to better contain leachate inside landfills. Our geomembrane‑supported GCL products have been widely applied in landfill projects worldwide.

Geomembrane Supported Clay Geosynthetic Barriers Introduction

Geomembrane‑supported geosynthetic clay barrier delivers premium anti‑leakage performance in the market. It combines smooth‑surface HDPE geomembrane with sodium bentonite which features excellent swelling and self‑sealing capacity.

It can work as an integrated composite liner, replacing compacted clay liner or geomembrane‑compacted clay composite liner for multiple environmental‑related projects: solid‑waste landfill, hazardous‑waste landfill, C&D waste landfill, storage reservoir, artificial lake, parking lot, basement, livestock waste containment etc.

Its performance meets or exceeds GCL (GM‑GF related) requirements as well as Chinese national standard JG/T193‑2006.

Features

• Self‑attaching and self‑sealing property

• Waterproofing and protective for underground concrete structures

• Solvent‑free and non‑toxic

• High tear resistance and tensile strength

• Simple and fast installation

FAQ

Q: Can you accept OEM orders?

A: Yes. Normally OEM order quantity needs to reach one 20ft container loading volume, around 18 tons.

Q: What is your MOQ?

A: For in‑stock geomembrane‑supported GCL, MOQ is one roll. For non‑stock regular specifications, MOQ is 1000m².

Q: Can you provide overseas installation service?

A: Yes, we can provide overseas installation service with competitive rates.

Solid‑waste & liquid‑waste disposal and recycling are major challenges for governments globally. Geomembrane‑supported GCL has become a commonly‑adopted liner solution recommended by engineers worldwide. Besides landfill projects, our products are widely used in hydraulic constructions such as dams, channels, canals, golf‑course waterproofing and other anti‑seepage works.
