A contractors asked us about lime powder or cement and soil contamination. The contractor would like to scratch the soils surface then spread lime powder or cement, this is for the soil to be improved and more stable. After the lime powder or cement has been applied a concrete slab will be cast on place on top of this improved soil. Will lime powder or cement powder represent some sort of soil contamination if it is applied this way? Thank you very much.

Michael, I don't see any LEED issues here.

Lime is typically used to increase bearing capacity of the soils prior to, among other things, pouring a slab. Provided you local EPA affiliate is fine with this approach, and you can pull the permits, you are good to go. If your contractor is local to your project, I'm sure he already knows what he can get approved.
