DT CONDUCTIVE GEOTEXTILE is a proven geotextile composite solution that provides all the benefits of a cushion geotextile as well as providing leak detection with spark testing and liquid catchment, within the one install.

Use

The realization of a leak detection campaign by geo-electric method on single or double liner systems increases the safety of the containment structure with respect to environmental risks. This requires the installation of an electrically conductive layer between the two geomembranes (double liner system) or between the geomembrane and the subgrade (single liner system) if the subgrade is not conductive enough.

DT Conductive Geotextile is a needle-punched nonwoven conductive geotextile composed of a conductive grid made of Stainless-Steel cables. Placed under the geomembrane, it allows leak detection by geo-electrical methods and protects the geomembrane against puncture.

The applicable leak detection methods compatible with the DT Conductive Geotextile are Water puddle (ASTM D7002) and Arc test (ASTM D7953) for exposed geomembranes, and Dipole (ASTM D7007) for covered geomembranes.
