Concrete Slab Cracks
Concrete Slab Cracks
(OP)
I have a commercial building that the contractor poured a slab on grade and did not cure the slab. 2 days after the pour, the concrete has begin to develop hairline cracks. Is there anything I should have the contractor do to fix this problem?
TIA

RE: Concrete Slab Cracks
I would recommend that you hire a testing lab to take core samples of the slab and test per American Concrete Institute (ACI) requirements. A structural engineer can also assist in investigating the slab and the tests and make recommendations as to any repairs to the cracks or....most probable: remove the slab and replace as the lack of curing is highly undesireable and will most likely provide you with vast opportunities to spend money in the future for slab maintenance.

The second concern is that with cracks showing so quickly, it is likely that many cracks will develop and they will ultimately be fairly wide cracks.
JAE's advice to get a testing lab involved is good. I would take that one step further and make sure the testing laboratory has an engineer experienced in concrete materials and the evaluation of same. There are many things that can be learned from an appropriate investigation of the concrete, most of which are directed at making the contractor perform remediation or corrective action, up to and including removal of the slab and placement of new, properly placed and cured concrete.
If you are early enough in the game to withhold payment, this would be an appropriate step until the issues are satisfactorily resolved.
Keep us informed of the progress.
