Product by Category > Geotextiles > DT CONDUCTIVE GEOTEXTILE

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.


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.

Water puddle method (ASTM D7002)

Arc Method (ASTM D7953)

Dipole method (ASTM D7007)


  • Geocomposite that provides 3 functions: mechanical protection, filtration and leak detection
  • Homogeneous diffusion of electric current under the geomembrane
  • Compatible with geo-electrical leak location surveys: exposed geomembranes (Water puddle, Arc test) and covered geomembranes (Dipole)
  • Easy installation with a single product to unroll


  • Filtration
  • Leak detection
  • Mechanical Protection


  • Needle-punched nonwoven conductive geotextile
  • Conductive 50 mm x 50 mm grid made of Stainless-Steel cables
  • Standard roll size: 3.90 m x 200 m


  • TRI have conducted and verified the Water Puddle Method (ASTM D7002) as well as the Arc Testing Method (ASTM D7953) passing every time.
  • Groupe Alphard testing has verified the Dipole method (ASTM D7007) Passing on every occasion.
