Geosynthetic clay liners
Geosynthetic clay liners (GCLs) supplied by Shanghai Renzhong Industry Co., Ltd. are composite barriers that combine natural bentonite clay with geotextile facings. The liners exhibit a high swelling capacity that creates a tight seal when hydrated, and they possess an excellent hydraulic conductivity that limits fluid flow. Their lightweight construction reduces transport weight compared with traditional compacted clay blankets. The material also shows resistance to UV radiation, extending service life in exposed environments.
Typical GCL thickness ranges from 1.5 mm to 2.0 mm, providing sufficient barrier performance while remaining easy to handle. Standard swelling expansion is greater than 12 % under load, which ensures the bentonite expands to fill voids. Hydraulic conductivity values are commonly ≤ 1 × 10⁻⁹ m/s, meeting the requirements for landfill and hazardous‑waste containment. Tensile strength of the geotextile layers is usually around 0.5 MPa, allowing the liner to withstand handling stresses during installation.
These liners are widely used in landfill caps, retention ponds, and contaminated‑site remediation projects by civil‑engineering contractors and environmental consultants. Shanghai Renzhong offers the product in rolls that are 10 m long and 1.5 m wide, wrapped in protective film for shipment. Prospective buyers should confirm the minimum order quantity, desired packaging format, and Incoterms such as FOB Shanghai or CIF Shanghai before finalising the purchase.

Sourcing Geosynthetic clay liners from Shanghai Renzhong Industry Co., Ltd. - China Import Guide
When sourcing GCLs from Shanghai Renzhong, first verify the company’s harbour‑tier status and request a copy of its business licence and any recent quality‑audit reports. Confirm that the supplier can provide the specific thickness, swelling and hydraulic conductivity data that match your project specifications, and ask for test certificates to substantiate those values.
Discuss shipping terms early; FOB Shanghai is common for bulk rolls, while CIF can be arranged if the buyer prefers the supplier to handle freight to the destination port. Clarify the expected lead time for roll production and packaging, and whether the supplier can consolidate multiple rolls into a single container to optimise freight costs. Ensure the minimum order quantity aligns with the volume required for your site.
Plan for on‑site inspection or third‑party testing of the delivered liners to verify thickness, swelling capacity and hydraulic conductivity. Request that the supplier includes a calibration or test report with the shipment, and consider arranging a post‑delivery visual check of the protective film integrity. Keeping detailed inspection records will support compliance with environmental regulations and facilitate future procurement cycles.
