Radon Gas Mitigation Strategy |
Due to recent findings from a study conducted by Kingston, Frontenac Lennox and Addington (KFL&A) Public Heath, the Town of Greater Napanee is implementing soil gas control measures in new construction and additions of low-rise residential buildings.
The strategy applies to all building permits applied for after November 1, 2019.
Please note that the radon mitigation strategy does not contain provisions for existing buildings. The Ontario Building Code regulates new construction only and does not contain retrofit requirements for radon gas. As a result, the strategy is only able to address radon gas mitigation in new construction.
Owners of existing buildings should contact KFL&A Public Health, Health Canada or Tarion to learn more about the health effects of radon gas, or to learn more about their options for radon gas testing and mitigation.
What is radon gas?
Radon is a colourless, odourless and tasteless gas that is formed naturally by the radioactive breakdown of uranium contained in soil and rock. Radon usually escapes from the ground into the air where it mixes with fresh air resulting in concentrations too low to be of concern. However, when radon enters an enclosed space through cracks and holes in floors and foundations in a building, it can accumulate to higher concentrations.
Canada’s radon guideline is currently 200 becquerels per cubic metre (Bq/m3), and Health Canada guidelines dictate that radon gas concentrations above 200 Bq/m3 require remediation.
Radon gas in Lennox and Addington
Recent results from residential surveys completed by KFL&A Public Health released August 12, 2019 indicate 23.5 per cent of the 227 randomly tested buildings within Lennox and Addington exceed Canada’s recommended guideline for radon gas of 200 Bq/m3.
Radon gas testing
All radon gas testing will consist of long-term tests (minimum 91 days) completed during the winter season, between October and April, when windows and doors are generally closed, and are recommended to be carried out by a Canadian National Radon Proficiency Program (C-NRPP) certified professional.
You will need to purchase a testing device and place it in your basement or lowest occupied floor level the first winter after occupancy. Testing kits can be dropped off at KFL&A Public Health or sent back to the company directly using pre-paid postage. You should then receive your test results approximately 2 weeks from when it was sent in.
Depending on the soil gas control option chosen by the builder, the building may be subject to mandatory or voluntary radon gas testing requirements. Although all new homes are not subject to mandatory testing, Health Canada recommends that all buildings be tested for radon gas.
It is the owner’s responsibility to have the mandatory radon test conducted and submit the results to Greater Napanee’s Building Department
Test results
Where mandatory radon gas testing results come back over 200 Bq/m3, the building owner will be responsible for remediation work.
All new homes in Ontario come with a new home warranty that is provided by your builder and backed by Tarion. This warranty also covers excessive radon gas levels in new homes for seven years from the date of occupancy.
New Homes and Residential Additions
As part of the Radon Gas Mitigation Strategy, all new construction and additions to low-rise residential dwellings will require soil gas control measures in compliance with 9.13.4., and SB-9 of the Ontario Building Code.
The Soil Gas Mitigation Strategy document provides an explanation of each of the three options below:
Options for new home owners
If your builder chooses Option 1, the builder or their representative should point out the radon gas pipe on your pre-delivery inspection (PDI). It will be a white pipe sticking out of the foundation labeled “soil gas pipe”, to differentiate it from a bathroom waste pipe. You should ask your representative to explain how the testing works before the PDI is over.
If your mandatory test comes back above 200 Bq/m3, then the builder will be responsible for remediation work. Generally, this will include extending the radon pipe in your basement up through the house and venting it through the exterior with a fan. Every home and situation is different, so remediation work may vary. If the results come back below 200 Bq/m3, you have the option of whether or not you choose to remediate.
If the builder chooses Options 2 or 3, where voluntary testing results come back over 200 Bq/m3, the owner should contact their builder and Tarion Home Warranty to determine next steps. Generally, the remedial measures will include breaking the concrete and adding a pipe that vents radon gas out of the building. Price and type of remediation differs for every home. Again, if the results come back below 200 Bq/m3, you have the option of whether or not you choose to mitigate.
When building a home you can also request the builder select a different option if you would prefer. The builder probably needs to know before permits are applied for as the rough in will be completed around the time the foundation is poured.

Radon Gas Soil Mitigation Construction Requirements |
Due to recent findings from a study conducted by Kingston, Frontenac, Lennox and Addington (KFL&A) Public Health, the Town of Greater Napanee is implementing soil gas control measures in new construction and additions of low-rise residential buildings. This strategy applies to new building permits applied for after November 1, 2019.
Health Canada guidelines dictate that radon gas concentrations above 200 Becquerel’s per cubic metre (Bq/m3) require remediation. As such, this strategy requires soil gas control requirements as per the Ontario Building Code (OBC) subsection 9.13.4., and SB-9 (Requirements for Soil Gas Control).
Construction Requirements
Building permit drawings shall clearly indicate details associated with one of the following three radon gas mitigation options to be constructed on site:
Option 1 1. A 100mm diameter PVC pipe rough-in through the floor slab adjacent an exterior wall connected to a corrugated plastic soil gas pipe extending under the slab and terminating at or near the center in conformance with Subsection 3.2, Sentences (1) through (5) of SB-9, a. Minimum 150mm granular material for a radius not less than 300mm centered on the pipe, with the bottom of the pipe open to the granular, and b. The upper end of the pipe shall be provided with a removable seal, and labeled to indicate for “soil gas removal only”. 2. Mandatory radon gas testing in conformance with Subsection 3.2, Sentence (6) of SB-9.
Please note: where concentration levels exceed 200 Bq/m3, a subsoil depressurization system is to be installed in conformance with Subsection 3.2, sentence (9) of SB-9.
Option 1: Sub-Slab depressurization rough-in

*Please note that we are working towards making our website images accessible.
Option 2 1. A soil gas barrier on the foundation walls (bituminous damp proofing) in conformance with Division B, 9.13.4.2 (3), and 2. under the basement floor slab using 6 mil polyethylene lapped not less than 300mm in conformance with Figures SB-9A or SB-9B of SB-9, and 3. sealing along the perimeter of the basement floor slab and at all penetrations using flexible sealant (polyurethane caulking) in conformance with Division B, 9.13.4.2.(4)(a) and SB-9.
Please note: spray foam can be substituted as a radon gas barrier under basement floor slabs where installed in conformance with CCMC Evaluation Report 14073-R.
Option 3 1. A soil gas barrier on the foundation walls (bituminous damp proofing) in conformance with Division B, Sentence 9.13.4.2 (3) and Figure SB-9A or SB-9B of SB-9. 2. Installation of a sub slab depressurization system installed in accordance with Health Canada guideline "Reducing Radon Levels in Existing Homes: A Canadian Guide for Professional Contractors". a. A properly labelled 100mm PVC pipe shall be installed through the floor slab adjacent an exterior wall connected to a corrugated plastic soil gas pipe extending under the slab into a centrally located 150mm thick bed of granular material. In accordance with Subsection 3.2, sentences (1) through (5) of SB-9, and b. Above the slab, 100mm grey PVC piping shall be installed, extending either through the roof or the rim joist, and shall have a continuous duty centrifugal inline radon fan. Please note: where an ICF foundation is being used, and radon option 2 or 3 is chosen, replace “bituminous damp proofing” with “waterproofing membrane” approved for installation over ICF foundations.
Option 2 and 3: Damp Proofing and Soil Gas Control at floor and wall junctions

SB-9A - Solid Wall SB-9B - Hollow Wall

Required Inspections
The owner of a property on which construction takes place or their authorized agent shall arrange for the following inspections: 1. The installation of the rough-in soil gas pipe, and granular material prior to pouring the basement slab, 2. The installation of soil gas barrier on foundation wall (bituminous damp proofing) and under floor slab (6 mil polyethylene) prior to covering or pouring the basement slab, and 3. Sealing of the perimeter of the slab adjacent to the foundation wall and any slab penetrations (polyurethane caulking) prior to covering. 4. Pipe cap and labelling, and inline fan (where required) prior to occupancy.
Testing
Depending on the radon gas mitigation option chosen by the builder, the building may be subject to mandatory radon gas testing. It is the Owners responsibility to conduct the radon test to determine the radon concentration in the building and submit the results to the Greater Napanee’s Building Department. All radon testing will consist of long-term tests (minimum 91 days) completed during the winter season, when windows and doors are generally closed, and are recommended to be carried out by a Canadian National Radon Proficiency Program (C-NRPP) certified professional.
Testing Results and Mitigation
The following is required where mandatory radon gas testing results come back over 200 Becquerel’s per cubic metre (Bq/m3): 1. The Owner is responsible for mitigation and installation of a subfloor depressurization system. 2. Measures shall be taken to ensure that any resultant decrease in soil temperature will not adversely affect the foundation, and documentation to this affect is to be provided by a qualified person. After installation, the Owner is to submit testing results indicating levels below 200 Becquerel’s to Greater Napanee’s Building Department. Health Canada recommends that you hire a professional certified under the Canadian National Radon Proficiency Program (C-NRPP) as lowering radon levels in a home requires specific technical knowledge and skills to ensure the job is done properly. To find a list of certified professionals contact the Canadian National Radon Proficiency Program (C-NRPP) at 1-855-722-6777.
