Imerys Civil Engineering has a range of special bentonites for use in a two-phase construction of a slurry wall. These bentonites have high flow limit and low filtrate loss so as to support the trench during excavation. Additionally, they can remain stable during the placing of the sealing cement-based material without causing flocculation or sedimentation phenomena or high filtrate water loss. Examples of these bentonites are:
In Europe:
- IBECO B1
- IBECO HT-X
- IBECO S
- IBECO BCE
In North America:
- IBECO WP Standard
- IBECO SP (API Section 10)
