LANDFILL DRAINTUBE FT

To protect the groundwater table from the ingress of contaminated leachate, a waterproofing system is installed during the construction or extension of landfills. The next step is to use a drainage solution by DRAINTUBE^® FT to protect the geomembrane at the bottom of the cell and drain leachate towards a collector drain.

Placed on the geomembrane, DRAINTUBE^® FT makes it possible in just one operation to install filtration, rainwater drainage and mechanical protection of the geomembrane. It replaces the upper protective geotextile of the geomembrane, the layer of granular drainage materials and the filtration geotextile.

Connection to the collector via the Quick Connect system

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