ABSTRACT:
A trenching tool which digs a trench to depths of six to thirty feet. A liner carrier case is conveyed to the trench bottom from which is withdrawn an impermeable barrier liner; extended from the bottom to the top of the excavated trench. The liner casing is positioned at the trench bottom and forms a bottom seal for a vertical liner. The impermeable liner is deployed simultaneously with the trenching operation. The trenching, liner and bottom seal positioning of the liner casing, and backfilling, is all part of a coordinated operation.
