Geosynthetic Clay Liners (GCL) are high-performance hydraulic barriers made by bonding bentonite clay between geotextile layers. Known for exceptional swelling capacity, low permeability, and self-sealing properties, GCLs are widely used in landfills, ponds, waste containment, and environmental protection projects.
As a leading GCL manufacturer, Prime Terratech provides durable, reliable, and high-quality liners engineered for long-term seepage control and environmental safety.
Geosynthetic Clay Liner is a factory-manufactured hydraulic barrier that combines
sodium bentonite clay with durable geotextile layers. The natural swelling and
self-healing capabilities of bentonite provide ultra-low permeability, making GCLs a
perfect alternative to traditional compacted clay liners.
GCLs offer strong puncture resistance, high shear strength, and long-lasting waterproofing
performance. They are highly effective in landfills, canals, reservoirs, mining sites,
and contaminated soil containment applications.
Prime Terratech is a trusted manufacturer of Geosynthetic Clay Liners offering
premium-quality GCLs designed for critical containment applications. With advanced
testing, strict quality control, and excellent engineering support, we deliver GCLs
that ensure reliable environmental protection and long-term performance.
