Amrad is an insulated under slab depressurization panel and a key component in a radon gas mitigation system. The void created by the integrated channels serve as an air gap for soil gas collection. Radon gas is able to vent out to the exterior through the use of a connected PVC piping with a continuously running exhaust fan. This panelized solution with its unique channel design, void percentage, film and foam density creates a strong and durable panel, giving builders the ability to build an insulated concrete slab while meeting radon building code requirements and improving the indoor air quality for the occupants.
The channel pattern and ratio of solid to empty allows Amrad to replace 4” (102mm) of clean granular fill as normally required by the building code. In addition, the air gap created by the channels serves as a capillary break between the soil and slab, greatly reducing moisture related issues. Amrad’s High Impact Polystyrene (HIPS) film serves a dual function by providing the required vapor barrier under the concrete slab while acting as an air barrier to prevent any radon gas from infiltrating into the interior space. The Amrad film replaces the need for a dedicated soil gas retarding membrane as required by the building code.
