ABSTRACT:
A method of installing a groundwater containment system is provided utilizing a powered trenching apparatus. The apparatus includes a boom at an end thereof; a trenching tool coupled to the boom; and frame structure mounted with respect to the boom. The frame structure is separated into at least first and second adjacent compartments. Each compartment has an inlet opening and an exit opening. The method includes advancing the trenching apparatus to create a single trench with the frame structure being disposed within the trench. Filter material is fed through the inlet opening of the second compartment. A first, impermeable wall panel is inserted through the inlet opening of the first compartment. While the trenching apparatus is advancing, at least a portion of the first wall panel passes through the exit opening of the first compartment and at least some of the filter material passes through the exit opening of the second compartment in such a manner that the wall panel portion is contained within the trench between a wall of the trench and the filter material exiting the second compartment. Additional wall panels are inserted in to the frame structure and joined together to form a containment wall.
