Bentonite TSB/QSE
Use
The large swelling capacity makes Bentonite TSB/QSE suitable for:
- The complete repair of drilled-through or damaged clay layers
- Securing spring-loaded charges in the ground for seismological study
- Making dams, dykes and water barriers non-water-permeable
- Rapidly sealing damaged wells, etc..
- Careful and even dosing are required for an optimal result.
- Bridge formation can occur in the event of dosing too rapidly.
Description
Cylindrical bentonite rods (granules)made from 100 % activated sodium bentonite. A characteristic of Bentonite TSB/QSE is its considerable water absorption capacity, as a result of which it swells up considerably when in contact with water. The TSB/QSE quality is KIWA certified in the field of toxicological aspects.
Advantages
- The assurance of a strong, virtually watertight layer which can only be achieved using a pure sodium bentonite
- Has extra swelling capacity for sealing irregularities in the borehole wall or difficult to reach cavities
- Certified according to KIWA-ATA, therefore absolutely safe for use in drinking water areas
- Easy to apply
- Absolutely environmentally-friendly
Specification
Complies with the requirements set in BRL-K20236/01 for borehole clay for sealing boreholes in bottom layers with poor water permeability Supplied with KIWA certificate for Toxicological Aspects (ATA), which guarantees an environmentally-friendly product
