All new residential and commercial buildings constructed should include Radon Gas resistant techniques to prevent and control Radon gas and other soil gas entry. Radon Gas Expert sub-contracts from builders to design and install the components of a passive depressurization system or we inspect and certify systems installed by builders that meet Health Canada Guidelines.
Installation of a gas permeable layer prior to pouring the concrete slab. This minimum 102mm, porous clean gravel layer, allows the unrestricted movement of Radon gas and other soil gases beneath the structure’s concrete slab.
Above the clean gravel layer Radon Gas Expert installs a 10mil true vapour barrier with overlapped and taped seams before the concrete slab is poured and/or above the crawlspace floor as appropriate.
A Schedule #40 PVC riser pipe is secured in place and connected to a PVC Tee that is also in the gravel and connected to the perforated pipe or drain mat system.
comprehensive sealing and caulking after the concrete pad has been poured is critical to reducing radon gas levels. Expansion joints are sealed appropriately to enhance the effectiveness of the mitigation system.
Radon Gas Expert supports builders and new home consumers in ensuring these inexpensive, aesthetically pleasing systems are appropriately deployed during home construction. Health Canada recommends that Radon Gas measurement testing occurs within the first year of occupancy to ensure passive mitigation system effectiveness for new home purchasers.
The International Code Council’s International Residential Code Appendix “F” (www2.iccsafe.org) details best practices which Radon Gas Expert follows for Radon Gas Resistant New Home Construction with appropriate modifications in respect of domestic Canadian regulations.
