LANDFILL DRAINTUBE FTP

After operation, the landfills are covered by a final cover system It aims to limit the infiltration of rainwater into the waste (thus the generation of leachate) and to optimize the collection of landfill gas (LFG). 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’)
