Composite liner definition

Composite liner means a liner that consists of two or more components, which include a Synthetic Liner in direct and uniform contact with an underlying layer of prepared, low-permeability soil such that the net permeability of the resulting combination is significantly less than would be expected by reference to the permeability of the individual components layers.

Composite liner means a liner comprised of a geomembrane, that is underlain and in direct contact with a soil component.

Composite liner means a liner system consisting of two components: the upper component consisting of a synthetic flexible membrane liner, and the lower component consisting of a layer of compacted soil. The composite liner must have the synthetic flexible membrane liner installed in direct and uniform contact with the compacted soil component and be constructed of specified materials and compaction to meet specified permeabilities.

Examples of Composite liner in a sentence

• Composite liner" means a geomembrane placed over and in direct and uniform contact with a barrier soil layer and/or geosynthetic clay liner, without a leak detection or leachate collection layer between them.

• Composite liner systems have the special advantage of the inherent redundancy in the system, and consequently the significant reduction in leakage.

• Composite liner systems involve ‘sandwiches’ made up of several different materials.

• Composite liner system or sealed concrete liner can be used if the minimum separation to bedrock is met.

• In the 2015 CCR rule, the term ‘‘unlined’’ CCR surface impoundment included any unit not constructed with one of the following types of liners: (1) Composite liner; (2) alternative composite liner; or (3) liner consisting of a minimum of two feet of compacted soil with a hydraulic conductivity of no more than 1x10¥7 cm/s.1 See § 257.71(a).

More Definitions of Composite liner

Composite liner means a system consisting of two components; the upper component must consist of a minimum 30-mil flexible membrane liner (FML), and the lower component must consist of at least a two-foot layer of compacted soil with a hydraulic conductivity of no more than 1 x 10-7 cm/sec. FML components consisting of High Density Polyethylene (HDPE) shall be at least 60-mil thick. The FML component must be installed in direct and uniform contact with the compacted soil component.
