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. After application of the bentonite plug an auger hole with a diameter of 70 mm can be entirely closed off in about three days.
The bentonite plugs are available in several variations, all measuring 50 cm in length.
MODEL VARIANTS

Round:
Round bentonite plugs are very suitable for decommissioning old monitoring wells and extraction wells.
- E 10.91 Bentonite plugs 17 mm diameter. Seals boreholes up to 30 mm diameter in approx. 48 hours. Pack of 40 pieces
- F 10.93 Bentonite plugs 25 mm diameter. Seals boreholes up to 45 mm diameter in approx. 48 hours. Pack of 30 pieces
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.
