ABSTRACT:
A method for isolating an earth mass and for setting up barriers to ground water flow by displacing the earth block and injecting sealant into the separations under and around the block, the sealant, acting as a working fluid to displace the earth block. In one embodiment, the displacement process is aided by sealing the upper perimeter of the block. In another embodiment, earth blocks are displaced in a progressive manner where a region of active vertical displacement advances around the perimeter of a region to be isolated. In a further method, an earth block is separated at its base and partially displaced upward before the sides of the block are separated.
