(EN)
A trench liner system used for forming a dual containment trench and for relining an existing trench comprising a primary liner means (14) extending along the length of the trench, a means (16) for supporting the primary liner means within the trench, a means (168) disposed between the liner means and the supporting means (16) for spacing the liner means (14) from the supporting means (16), and a means for holding the primary liner means and the supporting means (16) to the trench walls. The supporting means comprises a plurality of pairs of elongated members disposed along the trench such that the rear surface of each elongated member is in contact with one wall of the trench (11) and the underside surface of each member is in contact with the bottom of the trench. The elongated members are in opposed relationship to each other.
