GeoBent GCL: Engineered to Outperform Traditional Clay Liners

Product Description:
Step into the future of containment with GeoBent, the Geosynthetic Clay Liner (GCL) that renders cumbersome, compacted clay liners obsolete. Our product is a sophisticated engineered composite, manufactured by uniformly encapsulating a high-purity, granular sodium bentonite core between two robust geotextiles. One side is a woven geotextile for strength, the other a non-woven geotextile to promote intimate contact with the subsoil. This controlled factory production ensures consistent thickness and performance, eliminating the variability and quality control issues inherent in field-compacted clay. When hydrated, the bentonite core swells to form a low-permeability, self-healing barrier that is more effective and far easier to install than 12-24 inches of compacted clay.

Key Features & Benefits:

• Space & Cost Efficient: Replaces feet of clay with a single, lightweight roll, drastically reducing excavation volume and material costs.

• Superior Hydraulic Performance: Offers lower permeability (typically < 5 x 10⁻¹¹ m/s) than most compacted clay liners, providing a more reliable barrier.

• Self-Sealing Properties: Swells to seal around minor punctures or irregularities in the subgrade, a critical advantage over rigid liners.

• Rapid Installation: Unrolls quickly, saving significant time and labor compared to the arduous process of clay placement, testing, and compaction.

Primary Applications:

• Base and cap liner for modern landfills

• Secondary containment for industrial facilities

• Liner for potable water reservoirs and irrigation ponds
