Geosynthetic Clay Liner (GCL)

Geosynthetic Clay Liner (GCL) is an internally reinforced 3-layer polypropylene composite with premium grade sodium bentonite to provide high shear strength and consistent low hydraulic conductivity, a critical performance criteria for GCL’s as an effective barrier against liquid migration and gases. This is achieved with premium quality sodium bentonite, using clean water for its hydration and maintaining the GCL in a confined state during the hydration process.



Offers better moisture absorbency and does not leach out easily during installation.

Mass per unit area of sodium bentonite is evenly distributed and retained for a uniformed low hydraulic conductivity.

Superior tensile strength and internal shear resistance with long term chemical biological resistance.

Prevents stretching and contracting during shipment and installation to ensure continuity and uniformity of the bentonite layer throughout the GCL.

Structurally stable when installed on slopes and suitable for applications in a hydraulic environment.
