Description:
The principle of action of waterproofing bentonite mats is based on the property of sodium bentonite, which, when fully hydrated, can increase in size by 16 - 18 times. If free space is limited in the presence of water, a stress state forms in the structure of the bentonite gel and the material becomes waterproof.
As a waterproofing material, bentonite mats have many advantages. When working with bentonite mats, there is no need to have special skills and special expensive equipment.
The ability of bentonite to "self - healing" saves from violation of the waterproofing properties of the material. During hydration, bentonite granules are “tightened” by the bentonite gel to the damage site.
Bentonite mats are an environmentally friendly product, which allows them to be used in the waterproofing of ponds for fish farming, while the material is resistant to aggressive environments, such as fertilizers, non - polar liquids (gasoline, diesel fuel, oil, etc. )
Main advantages:
- High resistance to hydrostatic pressure and low permeability.
- Bentonite clay mats are able to qualitatively restore the integrity of the waterproofing background due to the potential for swelling. Waterproofing does not lose its reliability over time, its service life is almost unlimited.
- The material is not afraid of the cycles "hydration - dehydration", "freezing - thawing".
- Installation can be done year - round in any weather conditions.
Areas of use:
- Landfills for solid household (MSW) and industrial waste (PO);
- Objects of accumulation of liquid industrial waste, sand tanks, sludge tanks;
- Reclamation of oil - contaminated soils, landfills and places of unauthorized storage of waste;
- Coating and isolation of clogged and contaminated soil;
- Oil and gas industry facilities (sludge collectors, LPG depots, trunk pipelines, sludge pits, pumping stations, loading racks, when arranging bushes for oil / gas / gas condensate fields);
- Tank farms, oil product storage terminals, tank farms;
- Mining industry facilities (storage and disposal sites for production tailings (tailings), heap leaching sites (HF), ponds - evaporators, hydraulic structures, ash dumps, salt dumps, slag dumps);
- Gas stations (gas stations), underground tanks;
- Waterproofing and strengthening of dams, dams, shafts, drainage channels and treatment of storm drains;
- Waterproofing and strengthening of slopes, slopes, bank protection;
- Automotive and railway facilities (roads on soft soils, transport tunnels, cargo yards, track and passenger facilities; metro facilities, station structures, underground passages);
- Impervious protection of pavement base structures;
- Industrial pools - storage of liquid industrial waste, wastewater, sludge and more;
- Artificial ponds - fire, decorative and landscape ponds, irrigation canals, etc.
- Preservation of cattle cemeteries, silos, reservoirs and manure storage sites, fish ponds. Complete with bentonite mats, bentonite granules (BentoGranBG) are used to spill laps. In places of engineering communications passage, a hydraulic gasket (Bentolock) is used, which is laid in cold joints of concreting.
