MINING ENGINEERING DRAINTUBE FT

To drain the permanent covers of mine tailings storage facilities, DRAINTUBE^® FT provides a suitable solution for the run-off water and/or biogas drainage, filtration and mechanical protection of the geomembrane against puncture. Installed over and under geomembrane, this drainage system helps discharge fluids towards a draining trench. It replaces the lower protective geotextile of the geomembrane 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. 

• Mechanical protection of the waterproofing geomembrane against puncture
• Effective rainwater drainage
• Improved waterproofing performance by limiting hydraulic loads on the geomembrane and pressure under the geomembrane
• Cost-effective and environmentally friendly solution as it replaces granular layers
• Preserves the properties of the containment layer
• Stability of the entire cover, even on slopes
• Product benefiting from more than 20 years of feedback
• Product easy to unroll and install

• Polypropylene geocomposite
• Roll width : 3.90 m
• Roll length : 50 m
• 3 diameters of perforated mini-drains : 16 mm, 20 mm and 25 mm
• 4 possible distances between mini-drains : 200 cm, 100 cm, 50 cm and 25 cm
