A method of plugging holes, in particular the plugging of drill holes in earth. The method consists of inserting an auger, having a bit at the lower end and a central rod about which is formed a helical land, into the drill hole and rotating the auger to cause material to be conveyed upward and out of the drill hole. As the auger is moved downward this will cause any plugs or debris within the hole to be removed. After the auger has been inserted to a sufficient depth the rotation of the auger is reversed, and bentonite or other plugging material is pour...


A capsule for plugging a drill hole having an opening at a surface and an inner diameter; said capsule comprising: a liquid soluble exterior cylindrical wall formed about a longitudinal axis and having upper and lower ends, said wall forming an interior chamber extending along a length thereof; a plurality of coarse ground bentonite chips packed within the cylindrical wall and substantially filling said interior chamber; and end caps closing said upper and lower ends of said cylindrical wall, said wall including at least one slot cut therein and extendin...
