Meeting the need for Waste Containment applications of all types
CETCO GCLs have been used in a wide variety of waste containment applications throughout the world. Our global technical support, sales, manufacturing and logistics allow us to serve projects of all types in any location.
Landfill liners and caps
GCLs serve as the clay component of composite lining systems used in industrial, hazardous and municipal solid waste landfills. They may be used alone or in combination with a geomembrane in a composite cover system, GCLs provide significantly lower permeability, improved ease of installation, an increased amount of usable space when compared to traditional compacted clay liners.
Highway and civil
GCL are used in highway and civil applications such as at airport de-icing facilities. CETCO GCLs are compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and to prevent excessive percolation, minimizing potential for groundwater contamination.
BENTOMAT® DN is a reinforced 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 is a non-reinforced needle-punched GCL consisting of a layer of sodium bentonite between woven and nonwoven geotextiles, which are needlepunched together.
BENTOMAT® CLT is a Composite Laminate reinforced GCL consisting of a layer of sodium bentonite between two geotextiles, which are needlepunched together and laminated to a textured geomembrane.
BENTOMAT® CL is a Composite Laminate reinforced GCL consisting of a layer of sodium bentonite between two geotextiles, which are needlepunched together and laminated to a smooth flexible membrane.
BARRICK GOLDSTRIKE MINE
The Barrick Goldstrike tailings bottom liner system consisted of an 80 mil HDPE textured geomembrane overlaying BENTOMAT DN GCL. The GCL was used as a replacement for the 1 ft of 1 x 10-6 cm/sec permability compacted clay liner.
FORT MCMURRAY OIL SANDS
Northeastern Alberta, Canada
The Suncor Pond 1 is an oil sands tailings pond located near Fort McMurray, Alberta, Canada. This region experiences an average winter temperature of -19 °C, with a record low temperature of -50 °C. Full-scale closure and reclamation activities had been underway at the site since 2007. In late 2009, infilling of the pond had been completed.
FRESH KILLS LANDFILL
Staten Island, New York
Fresh Kills landfill is one of the largest landfills in the world, comprising a total of 2,200 acres. The construction of the cap was to be completed over five construction seasons from 2006-2010.
PLANK ROAD LANDFILL
Patterson, New Jersey
Jersey Brownfield was formerly the site of a chemical recycling facility with soil at the site was heavily contaminated.
RASMUSSEN RIDGE PHOSPHATE MINE
Soda Springs, Idaho
The Rasmussen Ridge Phosphate Mine Tailing Storage Facility was implemented as part of the on-going Supplemental Reclamation Action as a demonstration project. The cap and cover system was designed to effectively eliminate surface water infiltration and potential runoff of trace concentrations of selenium contained in the waste rock.
