Anyone lay their own concrete?

I would pay to have it engineered, then you have a plan to follow to be sure you get what you are planning.

Is your soil expansive? Might want to go 6" thick slab?


You might want to form in some reinforcement beams into pad and around the perimeter.

You might even want to put a curb around the perimeter to prevent ground water from getting in should it get a bit wet outside.
