Mitigation Strategies

Overview: Ways in which radon may enter the living space can vary from one home to the next. As a licensed radon professional, we are able to analyze multiple factors and formulate viable options which will address the customer's needs. The rationale behind potential options  shall explained to the customer.
Sub-Slab Depressurization: A radon control strategy designed to achieve lower sub-slab air pressure relative to indoor air pressure by use of a fan-powered vent drawing air from beneath the concrete slab.
Sump & Drain Tile Depressurization: A radon mitigation system designed to draw soil gas from a perimeter drain tile loop (internal or external) that discharges water through a drain line by using a fan-powered vent drawing air from the system
Submembrane Depressurization (crawl space): A radon control technique designed to achieve lower air pressure in the space under a soil gas retarder membrane laid on the crawl- space floor, relative to air pressure in the crawlspace, by use of a fan-powered vent drawing air from beneath the membrane.
Air Exchangers (HRV): Under ideal conditions,  an HRV system may be used as a radon control measure. Balanced HRV systems supply outdoor air to the house while exhausting indoor air simultaneously.
* Diagnostic Testing (pressure field extension): A method to qualitatively measure the ability of a suction field and air flow to extend through the material beneath a concrete slab floor. This may allow to evaluate the effectiveness of a sub-slab depressurization system.
