The Global Standard for GCLs: Sodium bentonite-based GCLs provide an excellent hydraulic barrier in applications where leachate in direct contact with the GCL is relatively non-aggressive, or in composite lining applications where the GCL is overlain by a thermally welded geomembrane and hydrates from uptake of innocuous moisture from the subgrade.

BENTOMAT DN GCL is a reinforced geosynthetic clay liner (GCL) consisting of a layer of sodium bentonite between two nonwoven geotextiles, which are needlepunched together.

BENTOMAT ST is a reinforced GCL consisting of a layer of sodium bentonite between a woven and a nonwoven geotextile, which are needlepunched together.

BENTOMAT 200R GCL is a geosynthetic clay liner (GCL) consisting of a layer of sodium bentonite between woven and nonwoven geotextiles, which are needlepunched together.

BENTOMAT CLT GCL is a reinforced geosynthetic clay liner (GCL) consisting of a layer of sodium bentonite between two geotextiles, which are needlepunched together and laminated to a 20-mil (0.5 mm) double-sided textured HDPE geomembrane. The geomembrane component of BENTOMAT CLT GCL is compliant with the GRI-GM-13 specification for HDPE geomembranes, adjusted for a 20-mil thickness. BENTOMAT CLT GCL is also available with textured HDPE geomembrane thicknesses of 30-mils (0.75 mm), 40-mils (1.0 mm), and 60-mils (1.5 mm).

BENTOMAT CL GCL is a reinforced geosynthetic clay liner (GCL) consisting of a layer of sodium bentonite between a polypropylene woven geotextile and a polypropylene nonwoven geotextile, which are needlepunched together and laminated to a polyethylene geofilm.
