Import 4800gsm Sodium Bentonite Geosynthetic Clay Liner — Buy in wholesale FOB from Supplier in China

This 4800gsm Sodium Bentonite Geosynthetic Clay Liner (GCL) is a composite waterproofing membrane combining natural swelling sodium bentonite with needle-punched woven and nonwoven geotextiles. The 4800g/m² mass provides a high-density barrier that hydrates on contact with water to form a uniform, low-permeability layer, making it suitable for landfill caps, tailings ponds, tunnels, and man-made lake linings where long-term containment is critical. The needle-punching process locks the bentonite between the fabric layers, creating a stable structure that resists displacement under hydraulic pressure.

The liner uses sodium-based bentonite, which expands significantly when hydrated to seal punctures or irregularities in the subgrade. Standard industry grades for such GCLs include bentonite with a minimum 24-28 mL/g swell index and a permeability of 1×10⁻¹¹ m/s or lower when fully hydrated, though the supplier’s exact values should be confirmed. The composite is typically black or white, with a width range of 3m to 6m as specified by the buyer. The material’s damage resistance is enhanced by the geotextile reinforcement, which also improves tensile strength for installation on uneven surfaces.

Primary buyers include environmental engineering firms, municipal waste management projects, and infrastructure developers requiring reliable anti-seepage solutions for containment applications. The product is shipped as rolls, with typical lengths adjusted to project requirements. For bulk orders, the supplier can tailor specifications such as width and roll length, but buyers should verify compatibility with their project’s subgrade conditions and hydraulic loads. The liner is designed for export and meets ASTM standards, though specific certification details should be requested directly from Huatao Group New Geomaterial.

Huatao Group New Geomaterial is based in Shijiazhuang, Hebei, China, with its registered address at 2-0708 Yihong Building, No.298 Zhonghua North Street, Xinhua District. The company specialises in geosynthetic materials, including geosynthetic clay liners for environmental containment applications. Its profile indicates a focus on heavy-duty waterproofing solutions for infrastructure and environmental engineering projects, though specific details about its production capacity, certifications, or client base are not provided in the available data.

The supplier’s trust tier is classified as harbor, which suggests a verified but not yet highly responsive status. Response metrics such as rate and average hours are currently not available, indicating that buyers should anticipate potential delays in communication. Huatao Group New Geomaterial does not provide explicit claims about years in operation, factory size, or industry awards, so buyers should request these details directly to assess the supplier’s experience and reliability for large-scale projects.
