Radon mitigation with sealed crawlspace and partial walkout basement
Does anyone know of a resource that addresses radon mitigation for a foundation area with a sealed crawlspace and partial walk-out basement on new construction in Zone 3A?
I am assuming the crawlspace and basement mitigation systems can share an exhaust pipe and I have a good understanding of the under slab portion for the basement. So, what is the best method for the crawlspace?
