avoid radon gas in new construction

Radon Gas Resistant New Construction

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.

New Construction Techniques


Create a Layer

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.


Use Barriers

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.


Install Riser Pipe

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.


Sealing Concrete

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.
