I’m having a 4 inch thick patio poured in my backyard. I’m adding a small barbeque shelter and I’ve dug four holes you can see. They are only 16 inches deep so they are above the frost line. The intent here is to give the barbeque shelter more strength, and reduce the chance of cracking. Because I’m going to drill in anchors after it’s done.
My question is, do you see a major problem with having a continuous pour of Cement that creates one piece pour, including the patio and the thickened post areas?
If you see this as a major problem, what is the problem and how would you fix it based on what you see here before the cement is poured?

Thank you very much!!
