Crawlspace Work
Crawlspaces and scope of work: The Illinois 422 administrative code is specific to all aspects of radon mitigation, including crawlspaces. Crawlspaces are required to be sealed with a 6 mil. vapor barrier with a 3 mil cross-lamination. This radon vapor barrier is to be permanently fastened to the perimeter of the crawlspace foundation walls in the manner that these pictures demonstrate. This vapor barrier is installed in a manner that is durable enough for contractors to enter a crawlspace and work without damage if they are reasonably careful with tools.
Interior Installation
Interior radon mitigation systems: When possible, Radon Reduction Technologies tries to install a radon mitigation system to the interior attic space of the home. During this process, all of the fan components and electrical are installed in the attic space. The vent pipe will exit through the attic roof and appear as just another vent pipe on the rear roof of the home. This is the preferred method of installation for a radon mitigation system to preserve the aesthetic beauty of a home, and there are some additional advantages for the system. For example, the fan is not exposed to the elements, the radon mitigation system is less likely to have icing occur during extreme cold, and the cost of replacement should the fan fail is a little bit less. Here are some examples of interior radon mitigation systems we have installed.
Exterior Installation
Exterior radon mitigation systems: The characteristics of a home will sometimes only allow for installation of an exterior radon mitigation system. In these instances, we do our best to install your radon mitigation system in the most inconspicuous place possible. Many times that is in the same area as the central air conditioner. In some instances, we can install a low profile fan that looks like a utility box. Radon mitigation systems can also be painted to blend into the exterior of the home. Here are some examples of radon mitigation systems that were installed at the exterior of homes.
