Description
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)
