BENTOSUND 120E-45S

Special formulation based on a selection of additives & natural sodium bentonite specifically designed to be used for a foundation engineering works in every type of soils as :

Diaphragm walls
Barrettes
bored piles

It has been engineered to build strong mud viscosity in a fast way, providing a superior hole cleaning thanks to a high gel strength. Moreover, it is recommended in keeping under control lost circulation and formation sloughing, while promoting hole stability in unconsolidated formations. The specific function as a primary filter-cake-building, filtration-control and as suspension agent in freshwater or recycled water is particularly adapted to the different applications even in case of massive seawater and calcium contaminations.

Specific advantages and benefits

Provides shale control and lubricity with minimal viscosity increase (during contamination)
Working with any type of drilling equipment
Hydrates more than other types of Bentonite and is best for developing gels for suspension and controlling filtration
Small particle size, unique flat shape and high surface area of hydrated
Provides superior filtration values.
Promotes the deposition of thin, compressible filter cakes in the bore
Fast swelling
Effective across a wide pH range
Grouting effects
Good filtration properties
Low consumption
Low sensitivity to contaminants (especially soil, salt and cement)
Stable even at low usage concentrations (up to 30 kg/mc)

Application

BENTOSUND 120E 45S is specifically set-up for special foundation works in all kind of soils. Dosage changes according to the kind of use and to stratigraphy.
