1. A method, comprising:positioning a roll of a liner above a trench having two sides, a bottom and a length, such that an axis of the roll is oriented along the length of the trench;
positioning an edge of the liner above the trench such that the edge is oriented along the length of the trench;
forcing a portion of the liner between the edge and the roll into the trench such that the liner is supplied from the roll and extends into the trench to form a continuous, seamless barrier between the two sides and the bottom of the trench and an interior portion of the liner;
installing a reinforcement mat within the interior portion of the liner, the reinforcement mat having a length aligned with the length of the trench, and having a height aligned with the two sides of the trench;
filling at least part of the interior portion of the liner with a cementitious material that surrounds the reinforcement mat within the interior portion of the liner;
wherein a weight of the cementitious material forces the liner into contact with the two sides of the trench; and
allowing the cementitious material to harden.
