Sodium Bentonite Clay

Geosynthetic Clay Liner (GCL) are composite materials that combine outer layers of geotextile with a sodium bentonite clay core with low permeability. Bentonite is a natural sealant that acts (hydrates) on contact with water.

Geosynthetic clay liners (or GCL) represent the newest subset of geosynthetic materials. They are factory-made rolls of thin layers of bentonite clay that are embedded between two geotextiles or bonded with a geomembrane. Structural integrity is maintained through stamping, sewing, or physical bonding.

How do I install a geosynthetic clay liner?

Huisen now tells you from the perspective of a geosynthetic clay liner manufacturer that the installation of a geosynthetic clay liner requires the following three steps.

Step 1 – Excavate the area for the liner. The excavated area should be at least 12 inches deeper than the finished grade.
Step 2 – Prepare the area for the installation of the liner. Make sure the subgrade is free of any rocks and debris.
Step 3 – Install the geosynthetic clay liner.

What makes GCL different from other geosynthetic products is that it incorporates a woven geotextile for dimensional stability and is reinforced for increased internal shear strength. Huisen GCL offers an array of different features for applications requiring a wide range of load and slope conditions in mining, landfills and pond projects.

Bentonite clay contains natural minerals like calcium, magnesium, and iron that can provide additional benefits. Bentonite clay is formed from volcanic ash. It takes its name from Fort Benton, Wyoming, where it is found in large numbers.
