Radon Mitigation For Multi-Family

Radon mitigation is a must for any multi-family building, and there are a few different ways to go about it. Each method helps ultimately reduce the radon levels inside the building, taking into account the property’s configuration, age, and other key variables.

Sub-Slab Depressurization: A large collection point must be dug out from underneath the structure. This is done by coring a hole into the slab and manually removing the soil underneath until we have a good suction pit to work with. The size of the suction pit under the slab is dependent on the footprint of the structure. Larger buildings typically require multiple suction points to achieve maximum depressurization. Once the suction points are in place, we attach the proper piping and run it to the exterior. On the exterior, the commercial radon fan is attached and the vent stack runs above the roofline in accordance with EPA regulations.

Drain-Tile Depressurization: Drain-tile depressurization is simply a different way to achieve sub-slab depressurization with the only difference being the collection point. If the structure has a drain-tile system underneath the slab, we can attach our radon mitigation piping to that system to achieve negative pressure throughout the entirety of its footprint. Drain-tile depressurization is the most effective method of mitigation because of how freely the system can move air from underneath the building to draw the radon gas out.
