Provo, UT
I did a radon system for my customer with a different approach. Rather than doing a suction from beneath the slab, we used the drain tile. We had access to the drain tile as there was a nine foot plastic sump pit. We sealed up the top of this sump pit with an air tight cover and put the radon suction pipe down into pit. We installed fan on the outside above the sump pit. We were able to reduce the radon levels from 12 to below without any digging, concrete boring or excavation. We were pleasantly surprised how well the system worked.

We will crow. We are the most respect radon mitigator in the Intermountain region.
