Granulated bentonite for waterproofing

Granulated bentonite granulate – (0.5 to 2 mm) for waterproofing of ecological buildings, substructures or sealing of garden lagoons, ponds and well structures. The backfill of granulated bentonite creates a natural impermeable waterproofing layer.

What are the properties of the MQ Bento granulate?

  • Sorptive capacity to capture
    • odour vapour and air humidity;
    • spilled oils and other fluids;
    • improves the earth resistance of grounding systems;
    • liquid fractions from livestock bedding.
  • Reclamation properties
    • To fertilise sandy soils and surfaces
    • As an additive for mineral fertilisers, where it prevents their seepage into the subsoil while preventing crusting of the fertiliser during storage
    • To balance the moisture regime of soil substrates used to grow plants
  • Sealing capacity
    • Sealing of buildings and dams of water basins (wells, sumps) against ingress of surface water
    • Sealing of dams and minor seepage cracks to prevent water leakage
    • To ensure subsoil impermeability of parking, storage and assembly areas with the risk of release of harmful substances in the ground water
