Leak detection with conductive geosynthetics
To protect the groundwater from leachate infiltration, the construction or extension of Municipal solid waste and Industrial waste landfills incorporates single or double liner systems. The installation of a double geomembrane liner and a geoelectric leak detection campaign increases the safety of the entire system with respect to environmental risks. This requires the installation of an electrically conductive layer under the primary geomembrane in addition to a drainage system.
DRAINTUBE CONDUCTIVE is a conductive drainage geocomposite consisting of a conductive grid made of Stainless-Steel cables placed inside a DRAINTUBE product. Placed between the two geomembranes, it allows leak detection by geo-electrical methods, protects the geomembrane against puncture and drains any leakage during operation.
The applicable leak detection methods compatible with the DRAINTUBE CONDUCTIVE are Water puddle (ASTM D7002) and Arc test (ASTM D7953) for exposed geomembranes, and Dipole (ASTM D7007) for covered geomembranes.
Benefits
- One geocomposite that provides 4 functions: mechanical protection, filtration, drainage 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
- Cost-effective and environmentally friendly solution as it replaces granular layer
