What is the minimum thickness of concrete slab for a shed?

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.

Can you pour a 2 inch concrete slab?

What should the thickness of a concrete slab be for a shed?

The right concrete slab thickness is critical. A thin, brittle slab will crack under the weight of the shed and what you put in it. And an overly thick slab will cost more than it needs to and be more difficult to put in. The minimum concrete slab thickness we recommend is 100mm.

How much does it cost to build a concrete shed?

A timber sub-floor is built above the level of the concrete slab. This makes it more comfortable for the users if the shed isn’t purely for utilitarian purposes. Take a look at the sketch below to see what I mean. The plywood floor is lifted above the cold concrete surface.

What should I put on top of my concrete shed?

Lay some 6 mil poly on the gravel then install some 2 inch styrofoam on top of the poly. Extend the styrofoam 1 foot beyond the edges of the shed. The styrofoam will help insulate the ground and prevent frost from getting under your slab.
