Concrete slab with low psi
Concrete slab with low psi
(OP)
One of my clients called me and said the contractor really screwed up his basement concrete slab. He had some cores tested for psi and it was found to be 1,500 psi. Is there a way to fix this other than removing the entire slab and re pouring? The contractor also failed to install a vapor barrier.

I mean unless the client is OK with it. Then maybe a warranty or compensation?

if going the petrographic route be careful on the terms of failure. My experience with petrographic testing has been spotty at best.

If a residential or commercial standard basement (non-loaded) floor is on a solid "compacted fill dirt" that then is covered by a very poor grade (but "solid" concrete, then why not apply a full-thickness slab of good concrete right over the bad stuff?
Sure, it is not forklift compliant, not truck and trailer rated, but the extra height will make no difference in any of the basements that I have seen.
