Detailed Product Description

They are also used for waterproofing of buildings and other similar structures.
This swelling allows the bentonite to seal around penetrations, giving the GCL self sealing characteristics. During hydration, a confined layer of dry bentonite changes into a dense monolithic mass with no observable individual particles. A fully hydrated bentonite layer can have a hydraulic conductivity of appro ximately one hundred times lower than a typical compacted clay liner (CCL).
Permathene supply and install a range of GCL's from light to heavy grades. These are high performance environmental liner comprised of geosynthetic carrier components integrated with a layer of low permeability sodium bentonite. The rolls are supplied in wide widths, minimising seams. Installation is fast.
