Bentonite TSB

CLAYMINERAL

 

DESCRIPTION

 

TSB pellets are cylindrical bentonite rods (granules) made from 100 % activated sodium bentonite. A characteristic of TSB pellets is its considerable water absorption capacity, as a result of which it swells up considerably when in contact with water.

 

USE

 

The large swelling capacity makes TSB pellets 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.

 

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

– Easy to apply

– Absolutely environmentally-friendly
