Does a shed need a base if it’s on concrete?
A good solid and level base is always required for a wooden shed like the Adley 4′ by 6′ overlap apex shed, for example. You can use an existing area of concrete or paving if it’s big enough and level enough. A larger garden shed made from metal will also require a solid base.
How thick should concrete be for a shed base?
Concrete Shed Base Depth For ordinary garden sheds, a thickness of 3″ (75mm) is sufficient in most situations. On soft clay, or on larger buildings, increase the thickness to 4″ (100mm) laid on 2″ (50mm) of finely broken and compacted hard-core if required.

Do I need rebar for shed base?

Do I need a damp proof membrane for a shed base?
Excess water outside the shed must have an escape route away from the building. The foundation should contain a damp-proof membrane which should be inserted into the base at least 2″ higher than the surrounding land area. This prevents water drainage from the immediate surrounding soil running onto the base surface.
What is the best shed base?
A gravel base is an ideal foundation for small prefab sheds and can even be a good option for some portable garages. However, concrete is a great option for larger garages and any building that’s not pre-built with a floor. If it doesn’t have a floor, then a concrete foundation is a good option.
What should I put between wood and concrete?

Can you put a wooden shed directly onto a concrete base?
If your shed has bearers (pressure treated pieces of wood attached to the bottom of the shed), you can place your shed directly on concrete or paving slabs. The bearers will help protect the shed from moisture damage and create space for air circulation. The concrete or paving slabs must be level.
Are shed base kits any good?
Good advantages to using a plastic shed base A plastic shed base has a lot going for it. Firstly, it’s never going to rot – no matter how long it’s down for. It’s also built to be extremely rigid, even though it is surprisingly light in nature. Its lightness makes it very easy to move into place too.
Does a shed base need to be bigger than the shed?
When preparing a base for your shed, the base should be built bigger than your shed. This is very important! If the shed base is built to the exact size of the shed and you attempt to bolt the shed down, the impact of the drill can cause the concrete below to break and crumble.
