Radon Gas Mitigation - Sub-slab Depressurization

Installed below the vapor barrier, the multi-linear drainage geocomposite DRAINTUBE® GAS is used as part of the SSD system, replacing the granular drainage layer and separation geotextile.

It exhibits the following properties:

  • Non-woven geotextile layers needle-punched together with 25 mm (1 in.) diameter perforated mini-pipes regularly spaced on 2 m (80 in.) centers and running the length of the roll
  • Mini-pipes with a stiffness at 5% deflection over 3,000 kPa (435 psi)
  • Stable long-term drainage capacity even under high loads

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

 

ADVANTAGES

  • Approved solution for passive and active SSD systems for Radon Gas Mitigation
  • Reduction of the social footprint (less truck traffic and less noise for the neighborhood)
  • Reduction of the environmental footprint (85% less GHG emissions compared to the use of granular drainage material)
  • Costs saving (no polluted soil to excavate i.e. no fees for polluted soil disposal)
  • Very good Health & Safety records for the installation crew on site
