Polypropylene geotextile DRAINTUBE CONDUCTIVE

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). Connection to the collector via the Quick Connect system The Quick Connect system directly connects the mini-drains from the DRAINTUBE® CONDUCTIVE to the main collector drain. In the event of gas drainage, it generates negative pressure in the entire system.
