For building industry
Bentonites for building industry are by means of selective extraction and technological processing targeted on exploitation of their extraordinary geological properties. These bentonites are noted for their high swelling capacity, for impenetrability of mixed and compacted layers and for sealing actions by maintenance and building of reservoirs, waterworks and waste depots. Further building bentonites are used as suspensions in boring works, for fixing of unstable underlying beds, in deep foundation, etc. Moreover specific properties of these bentonites enable their application as fluidifier in paste-like masses, plasters, mortars and concretes.

Bentonit GA
Is suitable for standard works in drilling industry, grouting, sealing of water constructions.
Bentonit GAE
This product is suitable for challenging works in deep wells, grouting in unstable subsoils, building and sealing of water construction, subsurface and sealing of waste materials depots.
Alternative Application
For the production of suspension fertilisers, plastification additive to paste masses, facades, mortars, concrete, granulating stabiliser in concrete products.
Not to be used
Waste waters purifying.
Ekobent
EKOBENT is a fine grained bentonite material with a wide use in environmental, agricultural, building and water service activities. The basis of this back fill is natural bentonite, which is specific for its high contents of montmorillonit - active mineral giving the product the excellent properties.
Sorption ability to retain
- odours, damps and humidity
- spread oils and similar liquids
- liquid parts of litters of farm animals (thickening of dung before composting)
Re-cultivation ability
- For fertilising of sand soils and surfaces thanks to ability to keep moisture and nutriments in the root layer of soil.
- As an additive to mineral fertilisers, where it avoids their percolation under the topsoil and at the same time it stops crusting of fertilisers while storing.
- For balancing of moisture regime of soil substrates for planting.
Sealing ability
- For sealing of building and water storage reservoirs (wells, pits) against seepage of surface waters.
- For sealing of dams and minor percolation cracks in reservoirs against water losses.
- For ensuring watertight subsoil of parking, storage and mounting premises where leakage of dangerous substances into the underground waters is possible.
Bentonit 75
Can be used as buffer for improving soil imperviousness, retaining of moister, powder extinguishers, plastification additive in mortars, facades and ceramic masses.
