GEOCHEM ENGINEERING’s Geosynthetic Clay Liners are thin layers of Bentonite granular or powder (Na/Ca/Activated) layer, between two layers of geotextiles.
Our GCLs are offered in various kd values, Bentonite weights, Geotextile types or with Polymer membranes upper or lower layer, depending each project’s needs. Can be used in:
The low hydraulic conductivity of the GCLs allows to be used as a replacement to thick, difficult to build compacted clay liners to provide a barrier to liquids and gases, offering both a technical and economical advantage
Geochem is offering GCLs for Landfill base lining uses, where the CCL is difficult to find or to constructed due to steep inclination. Our GCLs are used to limit the escape of landfill leachates or gases, in the construction of solid waste storage, heap leach pads and disposal site base liners and to inhibit the ingress of groundwater.
Benefits:
Our GCLs are used also to inhibit the ingress of water and the escape of fluid in the construction of solid or industrial waste facility cover or to cap contaminated soil.
Benefits:
Geochem offers GCL solutions in applications in which a significant water head is maintained, where our GCLs are generally used in combination with an existing soil barrier or in combination with a geomembrane, i.e., a GM/GCL composite. Under certain conditions they can be used alone.
In all cases, the function of the GCL is to reduce seepage through the system thereby reducing water loss from the waterway or storage impoundment.
