Standard Practice for Use of an Electrically Conductive Geotextile for Leak Location Surveys

Importancia y uso:

5.1 With the increased use of geomembranes as a barrier material to restrict liquid migration from one location to another, a need has been created for standardized tests by which the continuity of the installed geomembrane, including the seams, can be evaluated. This practice is intended to meet such a need whenever the subgrade soil is nonconductive, or a geomembrane is installed on a nonconductive material.

5.2 The use of a suitably conductive geotextile installed between a nonconductive soil or material and the geomembrane will permit electrical leak location survey to be conducted.

5.3 The compatibility of a conductive geotextile and leak location equipment shall be assessed for each leak location technique considered (covered or exposed, when applicable). A realistic small-scale test shall have been conducted by the supplier of geotextile and/or leak detection equipment to demonstrate their mutual compatibility for a given leak detection technique.
