Sometimes you just have to reach out and see if there are any experts on the board.
Back ground.
I needed to put a backyard concrete patio in, I knew where the concrete pad was to be located had bad drainage So I had the company that was doing the work come in and inspect in the spring. 6-8 " of water (clay under the grass)
One of the suggestion was to put 5-6" in the center and put 10" around the perimeter. The 10" on the outside would act as a curb and deflect water.
Along with changing the drainage this should solve the problem.
The 10" came with an extra cost but I thought it would really help.
------------------------------------------------------------------------------------
Now the issue, company pouring the concrete did not get a copy of the actual contract or the details and poured a 6" pad all around (re-bar / granular /etc was installed)
They only dug down a tiny bit so the 6" is level with the yard not dug down.
Not what at all was in a signed contract, will not help the deflection of water.
If water gets where I know it will the concrete will heave,
They offered me a 1 year warranty on heaving. (I laughed)
I was thinking a 10 year on heaving, I clearly have the contract and could sue but the fix is to remove and redo this is a major head ache,
I have the hold back on 50% of the cost and won't release it.
If this was you any options or things I can do
