I hired a couple of guys to pour cement in a new 10'x16'x5" garage ramp.
I have back problems so did not help with the project. I did frame and place expansion joint material along the garage door opening and positioned a gravel bed a rebar in preparation for the pour.
The two men poured the cement and floated it. When I went to look at it they had screeded the cement on the expansion material leaving the finished ramp almost an inch low and points where the rebar was actually showing.
Can I do another pour over the top of the first one? Will I need to do anything to prepare the surface for a second pour? Can I expect the ramp to hold up okay if I do a second pour over the first one?
