An apparatus for delivering liner material into a trench prevents sidewall collapse in a subsurface water saturated zone, provides for inspection of vertical joints, avoids the necessity for dewatering of an area to be trenched, and provides continuous rolls of liner material which are joined by vertical and horizontal seams to accommodate any length or configuration of placement. To initiate unrolling of a length of liner material, a roll of material is dropped into the installation apparatus which trenches into the subsurface. One end of the liner material is held in place by restraints and hydraulic presses. The roll is then unrolled by trenching backwards, cutting a trench and unfurling the roll in the formed trench.

A barrier wall installation system comprising: a tractor, a cutter assembly mounted on said tractor for digging a trench of a depth up to sixty feet, a roll of liner material, a delivery device mounted on said cutter assembly for locating a single layer of said roll of liner material in a vertically-oriented position in said trench simultaneously dug by said cutter assembly, said delivery device being vertically elongated and enclosed for receiving said roll of liner material positioned in a vertical orientation in said delivery device with the liner material being initially positioned in and emanating in said single layer from an elongated opening of said delivery device in a same orientation as the liner material will be positioned in the trench simultaneously dug by said cutter assembly, at least one of said delivery device and said roll of liner material including a connector for securing a trailing edge of one length of liner material to a leading edge of another length of liner material with a leak-proof joint, said cutter assembly digging said trench and feeding fill material into said trench simultaneously with unrolling said liner material from said delivery device, said fill material being the same material on both sides of said single layer of liner material.
