Abstract
A flexible trench liner system used for forming a single or a dual containment trench where during a trench overflow, the liquid run-off is prevented from migrating behind the primary flexible liner or behind the secondary flexible liner and possibly leaking onto the trench walls and bottom. The system includes an upper portion on the flexible liner means that overlaps at least a portion of the bearing surface of the trench. The overlapping upper portion of the flexible liner can be part of the primary liner and/or the secondary liner. The flexible liner means are held against the trench walls and the bearing surface by a holding means.
