Pipe for Radon Mitigation System
Having read a bunch articles on Radon, there does not seem to be a clear indication as to the location and length of perforated pipe (corrugated Big “O” or PVC Schedule 40) that should be installed.
Most of the article I have read simply seem to indicate placing a Tee connector under the slab with gravel around and some indicate an optional of adding a length of 4-5 feet perforated pipe on either side of the Tee connector.
Any feedback as to what is the best option and material to use?
Attached is my slab on grade drawing showing two option (blue & red) as to what I was considering doing.
