Imerys Civil Engineering sealing bentonites are suitable for sealing liners in earth-construction, waste deposits, water engineering and lake sealing. In principle, when sealing the base, the edges, and the surface of landfills, several different ways are possible, regarding the sealing agent that is used and the way in which it is technically installed. This depends on the local soil quality and the present or potential pollution and on the safety requirements resulting thereof. Imerys Civil Engineering Sealing Bentonites have high water absorption capacity as well as high swelling potential, ensuring low water permeability in the application.
Such bentonites are:
- IBECO DEPONIT B4
- IBECO DEPONIT CA
- IBECO D
- IBECO SEAL 80
- IBECO BSP
- IBECO WB
These bentonites are available either in milled form for direct mixing with soil or in a granular form for GCL production.
