Bentonite plugs

10.9

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

Description

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 2.7" (70 mm) can be entirely closed off in about three days.

The bentonite plugs are available in several variations, all measuring 20" (50 cm) in length. 

Regular

  • 10.94 Bentonite plugs 1.3" (34 mm) diameter.
    Seals boreholes up to 2.7" (70 mm) in diameter. Pack of 20 pieces

Round 
Round bentonite plugs are very suitable for decommissioning old monitoring wells and extraction wells.

  • 10.91 Bentonite plugs 0.7" (17 mm) diameter 
    Seals boreholes up to 1.2" (30 mm) diameter in approx. 48 hours. Pack of 40 pieces
  • 10.93 Bentonite plugs 1" (25 mm) diameter 
    Seals boreholes up to 1.8" (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.
