I have a 18in by 18in area in my basement floor that is open dirt. The house is measuring high for radon so I need to seal this up as it is a major source for radon getting into the house.
There are some water pipes coming out of the dirt area, and something else that you can just see the top of... not sure what it is. Can I cover this all with concrete and seal it up? That's what the radon mitigation company said to do. Would I ever need to access these pipes again?
