BUILDING CONSTRUCTION DRAINTUBE GAS

Construction of new buildings on old industrial sites with polluted soil or on areas with the potential for elevated indoor radon levels, requires the installation of a sub-slab depressurization (SSD) system as a mitigation system.

Installed below the vapor barrier, the DRAINTUBE^® GAS geocomposite is used as part of the SSD system, replacing the granular drainage layer and separation geotextile. It has a high and stable over time drainage capacity, even under heavy loads.

DRAINTUBE^® GAS is mechanically connected to the exhaust pipes using the Quick Connect system. It reduces pressure losses and improves the overall SSD system performances. DRAINTUBE^® GAS is compatible with active SSD.

Connection to the exhaust pipe using the Quick Connect system

The Quick Connect system connects the mini-pipes of the DRAINTUBE^® GAS directly to the collector pipe. This ensures that the overall system is depressurized, and it reduces pressure losses.

• A proven solution as sub-slab depressurization system
• Effective gas drainage (LFG, radon, etc.)
• Compatible with passive and active depressurization systems
• Reduction of the required excavation and disposal of polluted soils
• Reduction of the social footprint (less truck traffic, less neighborhood disturbance)
• 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)
• 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’)
