Bentonite CSK

Use

For the production of a supporting slurry to be used during the excavation and installation of diaphragm walls, the two-phase system. For optimal efficiency the mixing water of the suspension should have the following properties:
Conductivity: ≤ 1000 µS/cm
pH: 4,5 – 9,0

Description

The basis for this bentonite quality is a specially selected, activated sodium bentonite. Bentonite CSK has been developed for use as a high-yield diaphragm wall bentonite.

Advantages

Good trench stabilising properties
Allows easy handling in the desilting installation, therefore high yield
Outstanding price - quality ratio
Minimum effect on excavation speed
