PRODUCT DETAILS
1. Product Overview
Longxiang New Materials is a leading manufacturer and supplier of high-quality Geosynthetic Clay Liners (GCLs). Our GCLs are high-performance needle-punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier.
Designed to replace traditional compacted clay liners (CCL), our GCL products offer superior hydraulic performance and are ideal for waste management, mining, and water containment projects. As a direct factory, we provide wholesale pricing and custom dimension solutions to meet ASTM standards.
2. Key Features & Benefits
Self-Sealing Capability: The sodium bentonite core swells when hydrated, effectively self-sealing minor punctures during installation.
Superior Impermeability: Offers better hydraulic performance than meters of compacted clay, ensuring maximum leak protection.
Cost-Effective Installation: Lightweight and easy to deploy, reducing transportation costs and installation time compared to traditional soil barriers.
Shear Strength: Needle-punched reinforcement locks the geotextiles together, providing excellent internal shear resistance for slope applications.
Eco-Friendly: Made from natural materials, safe for environmental containment projects.
3. Applications
Our Geosynthetic Clay Liners are engineered for a wide range of containment applications:
Landfill Liners & Caps: Base liners and final cover systems for municipal solid waste (MSW) landfills.
Mining Solutions: Heap leach pads and tailings dams.
Water Management: Artificial lakes, canals, reservoirs, and storm-water impoundments.
Environmental Protection: Secondary containment for fuel storage tanks and groundwater protection.
Transportation: Waterproofing for highway and railway embankments.

6.FAQ
- Q: What is the difference between GCL and Geomembrane?
A: A Geosynthetic Clay Liner (GCL) uses bentonite clay for self-sealing waterproofing, while a Geomembrane is a plastic sheet (like HDPE) that acts as a physical barrier. Often, they are used together in a "composite liner system" for maximum protection.
- Q: How does GCL work?
A: When the sodium bentonite clay inside the GCL comes into contact with water, it hydrates and swells. Since it is confined between geotextiles, this swelling creates a dense, highly impermeable barrier that prevents liquid leakage.
- Q: What is the typical lifespan of GCL?
A: When properly installed and covered, GCLs are designed to last for decades. Natural bentonite does not degrade over time, making it a long-term solution for containment.
