And I continually look for smart, high quality innovative products that help us build better, healthier homes so I highly recommend you consider Radon Guard and Radon Block by Radon Environmental. Many different products are available that can be used in the installation process of a radon reduction system. This method has been shown to be highly effective at reducing radon concentrations in a building. Radon fans run continuously, and a system pressure monitor is installed for the monitoring of the system. The system relies on the radon fan to induce a pressure difference to exhaust soil gases and radon from under the slab. System Level 3 uses the pipe from Level 2 and also includes a low wattage radon fan.

Level 3- Full Active Soil Depressurization This level is now being used in the BC building code. The system relies on naturally occurring pressure differentials generated by the stack effect to mitigate radon. Provisions must be taken to ensure the pipe is properly sealed to ensure re-entrainment of radon does not occur. Level 2 is an extension of Level 1, where the pipe from Level 1 is extended up through space vertically and out through a wall to terminate outdoors. Level 2- Full Passive Vertical Radon Stack It is also crucial that areas around the sump pit, floor drains, and other pipes are sealed as well as caulking any cracks and joints in the foundation. According to CARST most provinces and territories have adopted this method. In addition, this level also includes a membrane installed underneath the concrete slab, which is sealed to the foundation wall to minimize radon ingress. This system is only a rough-in and can have a radon mitigation fan system added if required. The pipe then terminates just above the slab and is capped. A pipe extends into a soil gas collector (often gravel) under the foundation floor, which acts as an entry point for radon and other soil gases to a radon-reduction system. Level 1 is a rough-in for a radon-reduction system. Level 1 is a Rough-In for Active Soil Depressurization for Radon Reduction

There are three levels of radon reduction systems that builders can install into new construction. I’ve been working with builders throughout Canada who are incorporating radon mitigation techniques right into their builds. RELATEDįind out more about Radon Testing Options. Before 2007, the national guideline for radon was 800 Bq/m3. The Canadian guideline for radon dictates that a home should not contain more than 200 Bq/m3 or 200 units of becquerels per cubic metre. Radon is measured in becquerels, which is a unit used to measure radioactive concentration. Therefore, that means it can penetrate through even the tiniest holes in a house. Radon can seep into a home through soil, windows, cracks in foundation walls and floors, loose pipes fittings and support posts, floor drains and sump pumps, wall, floor joists, and even through your water facets! Remember, concrete is porous, and radon is a gas. Because long-term exposure to radon gas is harmful and can even lead to lung cancer.Ĭheck out the Radon Potential Map of Canada but remember, that any home can have dangerous radon levels, regardless of geography.Ĭredit: Courtesy of Radon Environmental Corp. Radon is present in every indoor environment, so it’s vital that homeowners must have their homes tested. I’m glad to see many builders taking steps to include rough-ins for radon mitigation systems. Besides, radon levels will fluctuate at various times throughout the year, and concentration levels vary geographically. Radon Reduction System in Home BuildingĮvery home has some level of radon. It’s important that you talk to your builder about radon mitigation systems. But what about new builds and new construction? Do they have radon? The short answer is yes. I’ve been talking about the dangers of radon gas for years now, and we test every home we work on for radon and take the necessary steps to mitigate it.
