Abstract
A trench liner system used for forming a single or dual containment trench comprising a primary liner alone or a primary liner with a secondary liner. In a single containment trench, a primary liner means extends along the length of the trench, and includes a plurality of ribs or pleats spaced laterally along the exterior side of the primary liner, so that the primary liner means is supported within the trench by the ribs or pleats and plurality of cavities are formed between the primary liner means and the trench wall and bottom. For a dual containment trench, the secondary liner means also comprises a plurality of ribs or pleats spaced along the exterior side of the secondary liner, so that the secondary liner means is supported by the ribs or pleats and a plurality of cavities are formed between the secondary liner means and the trench wall and bottom. The primary liner is disposed upon the secondary liner such that the exterior surface of the primary liner is in contact with the interior surface of the secondary liner. The primary liner is also supported by ribs or pleats and a plurality of cavities are formed between the primary liner and the secondary liner.
