To protect the groundwater table from the ingress of contaminated leachate, a waterproofing system is installed during the construction or extension of landfills. To control tightness in the short and long term at the bottom of cells, a DRAINTUBE® CONDUCTIVE drainage geocomposite is installed to check for leaks when building the structure and drain any leachate leakage during operation.
DRAINTUBE® CONDUCTIVE is a conductive geocomposite consisting of a conductive grid placed between a filter and a drainage layer. Positioned at the bottom of cells, between two geomembranes, it helps detect leaks by controlling the entire upper geomembrane using an electric brush, and mechanically protects the geomembrane against puncture.
The construction of a double waterproofing layer via geomembrane increases the safety of the entire system in terms of environmental risks.
Waterproofing control using an electric brush after implementation guarantees the total watertightness of the system. DRAINTUBE® CONDUCTIVE helps carry out these controls even when the two geomembranes are separated by a layer of air (electrically insulating).
This product performs 4 functions : mechanical protection, filtration, drainage and leak detection
Homogeneous flow of electric current under the waterproofing layer
Mechanical protection of the geomembrane against puncture
Possible leak detection when the geomembrane is apparent using an electric brush, or when the geomembrane is covered using the dipole-dipole method
