Advanced Radon Technologies, Inc. has been working with the Washington State Department of Ecology and The Environmental Protection Agency in the use of radon mitigation techniques to remove Volatile Organic Compounds (VOC's) in residential and commercial structures. We have also designed a methane gas removal system that could be used as a depressurization or pressurization system in a new construction application.

In addition to the building shown here, we are currently doing a project that involves approximately 40 residences and several larger commercial structures.

Spring isolators were used for vibration reduction. Three different spring weights were needed due to the load distribution of the stack.

Washington State Department of Ecology and the EPA required that the exhaust be a minimum of 15-feet above the roof to prevent reentry into the building. A 4" diameter stainless steel riser with a 24" attenuator had to be erected and anchored with guy wires.
