Concrete Pad

Had a contractor remove an existing pad 25'x3.5'x4". Original pad had cracked at the ends due to an eroding base. He used fast setting Quikrete (not sure of the exact type). I'm told he poured three times due to not having enough mix on hand - time between pours is unknown but the closest home depot is only 15 min away. This work was done on 11 Jun - 6 days ago. Contractor is suppose to return tomorrow to fix the problems in Q2.

Q1: Could this 'layering' of different pours cause problems, like one pour sliding off the other?

Q2: The current pad is not level and has many valleys were water if pooling. If 'layering' is NOT a problem, should he just be allowed to 'fill' in the valleys with more mix? Or should I demand he remove the entire pad and start over?


New Question: Contractor actually agrees that the pad is sub-standard but has a cement truck receipt to show a single pour. To level out the top and take out the valleys - he proposes to take three inches off the 8 inch pad and install re-barb poles and a mesh to lock the remaining pad and the new pour.
This sounds good to me but would like some expert opinions.

Thanks again!

Concrete Pad

Unless all the pours were still wet at the time, they will act as separate layers. It would have been better if the fast set was not used. One of the concrete guys will be able to explain the future ramifications.
