Overview

Features & Benefits of CETCO GCLs

Industry-leading internal shear strength without reliance on supplemental processing provides high safety factor on steep slope designs
SUPERGROOVE^TM technology allows bentonite to migrate out and create a self-seaming overlap reduces costs for bagged bentonite and associated labor
Lamination capabilities to provide composite geomembrane-GCL products
Granular bentonite for consistent hydraulic performance with no dust problems

Alternative to Compacted Clay

Geosynthetic Clay Liners (GCLs) are frequently used in environmental containment applications as an alternative to traditional compacted clay liners. GCLs consist of layers of geosynthetics surrounding a layer of low-permeability sodium bentonite. The materials are needlepunched together into a lining material capable of resistance to high shear forces.

Advantages over Compacted Clay Liner Systems

Self-Healing and Self-Sealing
Better Hydraulic Performance
More Resistant to Varying Weather Conditions
Faster and Easier to Install

Chemically resistant GCLs

Through extensive knowledge of clay-polymer interactions, CETCO has engineered GCL technologies capable of withstanding aggressive leachates. RESISTEX® formulas utilize a blend of high performance bentonite, with polymers that enhance the properties in extreme conditions.
