The concrete construction crew will start off by leveling the ground and adding gravel if needed. A wooden frame will be built around the perimeter of the pour. Think of it like a mold that a sculptor uses when pouring plaster or wax. It is there for form only and will be removed once the concrete has hardened a bit. Rebar or a wire mesh will be added depending on the structure’s use and how thick the concrete slab will be. The concrete will then be poured, spread out, and leveled. It can be finished in several decorative ways or kept as plain concrete.
