soil upheaval causing concrete to rise and crack
soil upheaval causing concrete to rise and crack
(OP)
We already demolished the concrete and plan on replacing with a new concrete slab but I am not so sure how to deal with the original soil that expanded when a 2" underground emergency eyewash/shower line leak. What should I do with the original soil? Do I need to excavate and replace it with new non-expansive soil? Can I re-condition and re-use the original soil and how do you re-condition such soil?

As Ron says, if it is expansive clay, then replace or do the lime thing.
If you are unsure, I'd ask a local geotech expert or soils lab.
