A hole is cut in the basement slab, a cavity is excavated beneath the slab, and 3" or 4" diameter PVC pipe is run up from the slab, out the basement wall, and connects with an exterior mounted exhaust fan. From the fan, an exhaust pipe runs up at least 10 feet above ground level, and 10 feet from any windows. Click on the thumbnails for full page images.
