IMPER-WALL UNDERGROUND CUT-OFF

The paper reports on a method of creating a continuous impervious curtain of grout in the ground by means of pile-driving methods. The method comprises a series of piles with flanges against one another driven into the ground. To each of the piles is welded a steel pipe 1 one-half inch inside diameter through which a cement-based grout was pumped down to the tip of the pile. The piles are then extracted; simultaneous with the extraction of each of the piles, grout is pumped in to replace the space occupied by the I-beam pile. After extraction, the piles are then driven in line with the first ones to prolong the cut-off wall. The key to the effectiveness of the Imper-Wall is the grout, which is basically a cement-fly ash mix.
