They also had a different contractor put concrete between the pole barn and the garage before the driveway was poured. That contractor said he couldn't get the driveway poured and completed before winter so they had contractor #2 do the driveway. The concrete that contractor #1 poured is cracking and moving. The difference?

The first contractor screwed them. They weren't there when the work was done, and he shuttered the business doors 6 months after work was completed so there is no recourse to recoup the $$. Supposed to have been the same specs - rebar and fibers, 5" thick, etc. I ended up cutting in an expansion joint (because the concrete was expanding and moving so much that it would twist and bind the service door closed on the pole barn) and found that the contractor did NOT put any steel in the concrete, just had the fibers, he did NOT compact the dirt under the concrete and it was NOT 5" thick. The concrete varied in thickness from 2 1/2" to 4 1/2".

That slab is 40' x 50'.

Mom & Dad also had that same first contractor pour retaining walls and a concrete walkway to their walk-out basement. This Spring they had to have contractor #2 come and tear out all of that concrete and replace it. The two 40" tall x 8" thick x 50' retaining walls tipped in 3" at the top, and the 50' x 8' walkway was heaving and cracking.

No footings under the retaining walls, and the retaining walls weren't tied to the concrete walkway with rebar and there was no steel in the walkway or walls........

edit: This is a good example of what Tony is talking about i.e., good vs. poor concrete work.
