Passive System
When applying radon mitigation techniques to new homes, installing a passive system is the way to go. Requiring the mitigation contractor to make multiple trips during the building process to ensure the systems effectiveness. Venting can appropriately be hidden in the interior walls or plumbing chases. A passive system performs best with clean/coarse aggregate beneath the home. Stack effect will cause underlying air to rise through the venting and is then vented out through the roof into the atmosphere. Typically a passive system will only reduce radon levels by up to fifty percent. After the home is complete a test should then be conducted. If levels are high, a fan can easily be added to maximize radon reduction.

EXISTING HOMES SUB-SLAB

This is the most effective/common method. First you start off by conducting communication tests to see if you have sufficient air flow beneath the concrete slab. After all diagnostics are performed you can determine what size fan you need, if multiple suction points are needed, and placement of venting. Piping is installed in the least obstrusive way possible.

SUMP AND DRAIN TILE

​This is​ another very effective method. If you have drain tile routed to a sump pit this is a good way to suction the air out from beneath the basement slab. A specialized sump lid is retro fitted for a tight seal to prevent air loss and entry for radon. Allowing suction to channel air through the drain tile and out through the discharge pipe. Drain tile can also be tapped into on the exterior of foundation/footing.

CRAWL SPACE

With a crawl space you use the same concept as the other methods but you are suctioning air beneath heavy duty plastic, if it's a dirt/gravel base, the plastic is caulked around the perimeter up onto the wall at a minimum of 12". Making sure all the seams are overlapped and sealed using an appropriate caulk. If you have multiple crawl spaces then each one is treated as its own. If any asbestos or hazardous materials are present it is up to the homeowner to have it professionally removed before installation.
