Mesure de radon

Radon is measured in becquerels per cubic meter of air (Bq/m³). Health Canada recommends that corrective measures be taken when the average annual radon concentration exceeds 200 Bq/m³ in occupied spaces of a home. However, it is up to each owner to determine if a rate less than 200 Bq/m³ is an acceptable level of risk to their health and family. To reliably measure the radon concentration in a building or to determine if the installation of a mitigation system is required, it is first necessary to install a long-term measuring device, 90 days minimum. Although it is possible for you to install the measuring device yourself, it is strongly recommended that you hire a professional certified by the National Radon Proficiency Program in Canada (PNCR-C), like us.

Systèmes d’atténuations de radon

If the radon gas exceeds 200 Bq/m³, you should resort to corrective measures depending on the type of dwelling and the type of construction. The higher the concentration of radon, the more important it is to take corrective action quickly. Our certified radon mitigation professionals ensure that the installed radon mitigation system reflects the latest approaches and techniques. A poorly designed or installed mitigation system can have serious repercussions on a home's energy costs and on your health. Our certified PNCR-C program professionals have the training and tools to ensure that the system has the least possible impact on home heating and cooling costs and that they will be efficient for the entire floor space of your property.

Dépressurisation active du sol sous la dalle (DAS)

Depressurization of the soil under the slab is the most common technique used in residential settings. A pipe system and a radon exhaust fan are installed to extract radon and all other gases present in the ground, under the house and then expel them outside. When these systems are properly designed and installed, they can significantly reduce the radon levels in a home.

Dépressurisation sous la membrane (DSM)

This type of depressurization targets radon levels present in crawl spaces where soil and rock are exposed. Using this approach, the radon is extracted under a polyethylene film placed to cover the exposed surface, then evacuated from the house using a ventilator and pipes.
