Polyethylene geotextile DRAINTUBE FTP

At the end of their operation landfill cells must be closed and covered with topsoil. To allow the ingress of rainwater in the waste mass with a view to guaranteeing its degradation over time, providing the cover with a semi-water barrier with DRAINTUBE® FTP is necessary. This solution is used on cell caps to drain rainwater and provide the landfill cover with a semi-water barrier. DRAINTUBE® FTP is the combination, by means of needling, of DRAINTUBE® FT with a polyethylene film to help limit water seepage in waste. The film is 70% needled, meaning that 30% of the surface of the geocomposite is impermeable. Connection to the collector via the Quick Connect system The Quick Connect system directly connects the mini-drains from the DRAINTUBE® FTP to the main collector drain. In the event of gas drainage, it generates negative pressure in the entire system. • Filtration of the cover soil layer • Effective drainage of rainwater • Limitation of the infiltration of rainwater through the final cover: less than 20% • Stability of the final cover • Easy installation with a single product to unroll • Cost-effective and environmentally friendly solution as it replaces granular layers • Preservation of the mechanical characteristics of the containment layer
