A method of constructing a fluid impermeable wall in the ground. A first trench is dug and simultaneously filled with a cementitious bentonitic mud, which is sufficiently viscous to prevent the sides of the trench from caving in. This first trench forms a first section of the wall. Before the mud of the firt section has set, a second trench is dug adjacent to and continuing or extending from the first trench, to form a second wall section, and the second trench is also simultaneously filled with cementitious bentonitic mud. The abuttting end sections then bond firmly together upon setting to form a continuous wall. |
