Bentonite Membrane

Bentonite Membrane

It is a waterproof and airproof material obtained by composing Sodium Bentonite granules, which are placed between braided on one surface and unbraided geotextiles on the other surface.

Thanks to its high swelling capacity when it comes into contact with water, it provides waterproofing feature.

Geosynthetic clay liner (GCL) combine geosynthetics with sodium bentonite clay to form a highly impermeable barrier that often replaces thick layers of strong compacted clay.
