Tonight I finished one of the hardest and taxing radon systems I have ever done. The house is over 9000 sq ft on two floors, required two full active radon systems, had to use 4" custom finished copper pipe to match existing downspouts, had to core drill through 8" of concrete and 3" of natural stone, and we had to repair and refloat the entire basement floor because of massive cracking and lifting (some cracks had settled more than a 1/2") and a host of other things....whew!!!
