What concrete slump do I need?
A patio should slope away from the house at the rate of 1/8" (3mm) per running foot. Generally, a 4" (100mm) thick slab set 2" (50mm) above ground level is suitable. To ensure that the height and slope are correct, begin the excavation, layout and form construction where the patio meets the house.
Concrete Slump Reinforced foundation wall and footings: Slump shall be between 2 and 5 inches. Footings, caissons: 1-inch minimum, 4-inch maximum. Slabs, beams, building columns, and reinforced walls: 3-inch minimum and 6-inch maximum. Pavements: 2-inch minimum and 3-inch maximum.

No matter how strong a slab of concrete seems, it will wear out over time. Imperfections form when concrete hardens or sinks into the ground. Adding fresh concrete is a common way to level out old slabs and patch damage. If you plan on pouring a lot of concrete, build a wood and mesh barrier first to ensure your new slab is strong. Finish the work by priming the surface and pouring a mix over it, giving your concrete foundation a fresh, new coat.
Depending on the weather, pouring concrete all at once isn’t always recommended. If the weather is hot and dry, it is recommended to divide the slab down the middle with another piece of wood and fill in both halves on varying days to avoid rushing.
It’s best to use a large piece of wood to form it, with 2” x 12’recommended. When setting the height of the stakes, make sure to use the level so it is straight. When harming the form to the stakes or together, make sure to use 16d duplex nails, as these work best. [links]
One of the most important reasons is simple: it costs significantly less to do it yourself. That being said, if you don’t know the proper way to do it, it might end up being a big mistake. It’s all a matter of following the proper procedure in pouring concrete.
Make sure to get in contact with your local building department to see if a permit is required or not. You’ll need to have measurements of your home’s perimeter and the size of the slab itself. You should also start the process of drainage at this point as well. here
Naturally, you’re going to need some concrete mix and water, along with a host of other materials such as anchor bolts, 6-mil plastic, and duplex nails. You’ll also need a way to help reinforce the concrete form such as lumber, rebar, tie wire, and packable fill. more
In order to avoid any cracking and to just generally ensure that your slab lasts longer, it’s important to have proper drainage for your concrete. If you have sandy or clay soil, it isn’t completely hopeless, just give yourself enough room to add a layer of gravel. here
Do you want your shed to look level or look like it was built crooked?
If I were to use existing sloped pad I would pour footings around the perimeter (level of course) & build on that.
My obvious question is why throw good money after bad? more
I'd cut them individually and build it level myself.
