LANDFILL DRAINTUBE FT/PE
DRAINTUBE FT/PE - Water and gas drainage for caps
Use
At the end of their operation, landfill cells must be closed and covered with topsoil. To prevent the ingress of rainwater in waste, a water barrier must be installed in the cover using DRAINTUBE® FT/PE.
This solution is used on cell caps to drain rainwater and provide the cap with a water barrier in a single product. It consists of a DRAINTUBE® FT combined with a geomembrane which may have a textured underside to increase cover stability.
Connection to the collector via the Quick Connect system
The Quick Connect system directly connects the mini-drains from the DRAINTUBE® FT/PE to the main collector drain. In the event of gas drainage, it generates negative pressure in the entire system.
Benefits
- Rapid drainage of seeping rainwater
- Water barrier in the cover thanks to the overlapping of the geomembrane
- Cost-effective and environmentally friendly solution, does not require any granular material
- Stability of slopes and domes for revegetation
- Preservation of the mechanical characteristics of the containment layer
