How thick does a concrete slab need to be for a shed?

Can you put a shed straight onto concrete?
Placing a shed directly onto hardcore or concrete slab bases effectively traps a pocket of air between the base of your shed and the ground. This air pocket can become quite moist and the moisture then condenses on the wooden base of the shed, posing a risk of rotting from the bottom up.

Is it cheaper to pour concrete yourself?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
Is it cheaper to buy premixed concrete?
It’s cheaper to do all the prep and buy the concrete premixed and delivered. For example, a 10×20′ slab of 4″ concrete would be a minimum of 2.5-3 yards. Here concrete is about $80/yard (closer to $70), or $240 for the concrete. That same slab would take 223 40-pound bags, or 112 80-pound bags.
Is it cheaper to do pavers or concrete?
As far as installation costs and concrete costs go, poured concrete is technically the most affordable per square foot. However, even though the upfront cost of pavers is higher, concrete pavers offer greater value and durability than poured concrete and stamped concrete.
Do I need a concrete base for a shed?
Both paved and concrete bases can’t be laid straight onto soft ground and so require a sub-base. A concrete base also has a further extra step – constructing the frame or edging that supports concrete while it sets, this is known as formwork. We recommend only using a concrete base for larger sheds and log cabins.
How do you anchor a shed to concrete?
Dig holes, form and pour concrete piles at each corner and the middle if a long shed. Use anchor bolts with a loop or ring top and inserted into the concrete before it hardens. Connect a cable or strap to the ring or loop to anchor the shed. This is a permanent anchor.
