LANDFILL DRAINTUBE CW

The construction of temporary covers allows the operator to limit the infiltration of rainwater into the waste mass (and thus the production of leachate) and also to collect the Landfill Gas (LFG) and limit odor problems while waiting for the construction of the final cover.

DRAINTUBE^® CW ensures the collection of LFG and waterproofing of the temporary cover with a single product and a single installation.

This geocomposite results from the combination of DRAINTUBE^® LFG with a coated woven polyethylene membrane.

Connection to the main header pipe using the Quick Connect system

The Quick Connect system connects the mini-pipes of the DRAINTUBE^® CW directly to the main header pipe. This ensures that the overall system is depressurized, reduces pressure losses, and increases the vacuum zone of influence. The Quick Connect system + T-Connect limits air intrusion into the landfill gas network.

• Optimization of LFG collection
• Gas collection and waterproofing with a single product
• Large zone of influence and high collection rate
• Better performance of the temporary cover by limiting LFG pressures on the geomembrane
• 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)
• Coated woven polyethylene membrane
• 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: 3.66 m x 51 m (12’ x 167’)
