Geo Synthetic Clay Liner Bentonite

BENA-GCL is selectively mined and processed high-quality sodium based bentonite powder to ensure a low permeability containment product ideally suited to applications of landfill containment. BENA-GCL is chemically modified bentonite powder which will generally give higher swell index values and lower fluid loss numbers when added with polymers. Generally, the calcium content must be kept to minimal levels as calcium montmorillonite has a much lower swelling potential than sodium montmorillonite. BENA-GCL does not contain any Fermentable Product and is Environmentally Acceptable.


Important Characteristics & Advantages of “BENA-GCL”
  • High Swelling Index
  • Lower Fluid Loss
  • Very high active surface area

Recommended Treatment: GCLs consist of a thin bentonite clay layer, which typically ranges from 5–10 mm, encased with geotextile. There are two configurations commonly used; in the first configuration, a layer of bentonite is encased between woven and non-woven geotextiles, which are needle-punched together; the second configuration is fabricated using a flexible membrane liner laminated to one side of the first type. Typical Bentonite mass per unit area using ASTM D5993 Standard is about 4 to 4.40 kg/m2 for reconstituted GCL.
