MINING ENGINEERING DRAINTUBE FTP

After operation, the tailings storage areas are covered by a final impermeable cover system. This is important for the protection of the environment by preventing the evaporation of tailings into the atmosphere or the infiltration of liquids (leaching) and oxygen (oxydation) of the ores. DRAINTUBE^® FTP provides rainwater drainage and impermeabilization of the final cover with a single product and a single installation.

This geocomposite results from the combination of DRAINTUBE^® with a polyethylene geofilm.

The needle-punched polyethylene geofilm on the underside of DRAINTUBE^® FTP limits the infiltration of rainwater through the final cover.

• 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

• Multi-linear drainage geocomposite (ASTM D4439)
• Needle-punched polyethylene geofilm on the underside
• Perforated mini-pipes made of polypropylene
• 3 diameters of perforated mini-pipes: 16 mm, 20 mm and 25 mm
• 4 spacing options between the mini-pipes: 2 m, 1 m, 1/2 m and 1/4 m (80’’, 40’’, 20’’, 10’’)
• Standard roll size: 3.98 m x 75 m (13.1’ x 246’)
