MEMBRANE OF RAW BENTONITE
LOWEST PERMEABILITY AND ULTIMATE STRENGTH
With a DantoCrude membrane, the low-permeability layer is dense and extremely robust.
The structure of a membrane may comprise many different materials and layers, but it is only the impermeable element of all these layers that retains water and contaminants.
All things being equal, a dense low-permeability layer is more watertight and robust than a thin low-permeability layer.
In contrast to other alternatives, the DantoCrude membrane will remain permanently flexible. The membrane will thus move with the substrate and adjacent built structures – year after year – ensuring that it remains watertight and intact. Time itself has no impact on its function.
Pure, raw DantoCrude bentonite clay is typically used in circumstances where you need to secure an area against contaminant seepage or for some reason you wish to stop water seeping down through the layers of soil.
DantoCrude is often used in connection with the establishment of landfills that require an impermeable base layer, or to secure a previously contaminated site against further seepage into groundwater layers by permanently cutting off the area from any supply of stormwater, for example.
STORMWATER AND WASTEWATER PONDS
When constructing ponds, DantoCrude is the perfect material for structures large and small. It doesn’t matter whether it’s a large stormwater reservoir for the storage of dirty run-off from roads or a natural little pond in a park. The key thing is that you receive easily understandable advice, to ensure that your project is completed properly and as cheaply as possible.
The specific conditions will determine whether DantoPlug bentonite pellets, DantoGran bentonite granulate, or our pumpable, hardening bentonite products from the DantoCon series are the best solution.
Whichever product you choose, they’re all based on Danish bentonite of the highest quality from our own quarry.
