Bentonite plugs are used for sealing boreholes, in order to prevent that water from different aquifers mix after augering. The plugs are available in various diameters.
- 100% seal
- Firm enough to be pushed down to desired depth
- Environmentally safe
- Unaffected by water pressure once swollen
The plugs can be used against intrusive seepage water and for decommissioning old monitoring wells and extraction wells. The material used and the plugs’ shape ensure a reliable hydrological sealing. The plugs consists of natural bentonite clay, without parts that could cause obstructions.
Note: Bentonite swells poorly in water with salinity, or electrical conductivity, of 20 mS/cm or higher. Water that is heavily polluted also inhibits the function of bentonite. Not suitable for use in pure hydrocarbon layers, as bentonite will not swell at all in that environment.
