Thanks, everyone. The goal was to lower the slab up to the footing, and he went a few inches beyond that. This particular contractor has completed many similar projects in the DMV area, so I assume he knows what he’s doing. The basement is already excavated, and this is the maximum...
Interesting. Why can’t most projects use the concrete bench method? What are the downsides of following the contractor’s suggestion? Wouldn’t the new slab act as a reinforcement/bench?
Is this concerning? I am lowering my basement. My contractor dug few inches below footing and that contractor says that this will be reinforced with gravel and concrete slab, and no need for underpinning.
