Waterproofing any liquid impermeable geotextile composite material which is composed of several layers of woven and nonwoven polyester or polypropylene geotextile webs, needlepunched interconnected manner are stitched between these layers is the main component - natural sodium bentonite which itself swells in contact with water.
It differs from the analogue in the commodity group mats Bentolock reduced content of bentonite, which makes the unit easier to roll 200 kg than similar material Bentolock GL10, wherein the waterproofing material properties are not reduced.

The operating principle of bentonite mats is based on the fact that the state prigruzhennye moisture getting into the material causes the clay to swell, and it turns into a waterproof gel. Waterproofing bentonite mats are based on the property of the clay. If water in the presence of limited space, the structure is formed of a bentonite gel state of stress and the material is waterproof.
As a waterproofing material bentonite mats have many advantages. When working with bentonite mat is not necessary to have specific work skills and a special expensive equipment.
The ability of the bentonite to the "self - healing" rescues from disorders waterproofing material properties. When hydrated bentonite granules "tightened" bentonite gel injury site.
Bentonite mats environmentally friendly product, which allows their use in the manufacture of waterproofing ponds for fish farming, wherein the material resistant to aggressive media, such as fertilizer, to the non - polar liquid (gasoline, diesel fuel, oil, and so on. N. )
- High resistance to hydrostatic pressure and low permeability.
- Mats of bentonite clay are able to qualitatively restore the integrity of the waterproofing background due to the potential swelling. Waterproofing does not lose its reliability over time, its service life is practically unlimited.
- The material is not afraid of cycles "hydration - dehydration", "freeze - thaw"
- Make installation possible all year round in all weather conditions.
Areas of use:
- Polygons municipal solid (MSW), industrial waste, and (PO);
- Objects accumulation of liquid industrial waste sand pond, silt - settling tank;
- Remediation of contaminated soils, landfills and waste storage places unauthorized;
