Abstract
A trench liner system used for forming a dual containment trench and for relining an existing trench has a primary liner and a secondary liner means extending along the length of the trench, a separating means is disposed between the primary liner and the secondary liner. A means for holding the primary liner, the secondary liner and the separating means against the trench walls has a vertical member having an upper end and an opposite lower end, with a first horizontal member extending from the upper end and terminating in a first edge. A first wall depends from the first edge and a second horizontal member extends from the lower end away from the first horizontal member. The second horizontal member terminates in a second edge having a second wall depending therefrom. The outer surface of the vertical member and the upper surface of the second horizontal member form a ledge adapted to receive grates and covers. In an alternative embodiment, the holding means has a horizontal member having a first end and a second end and a wall depending from the second end. The trench wall defines an opening therein to receive a portion of the horizontal member, with the depending wall overlying the upper portion of the primary liner means.
