Best answer

And yes, mesh is important: Concrete is strong in compression, but not under tension. So, if it flexes, like a slab with a vehicle on top of will do, it cracks at the bottom whre the flexing becomes tension. Steel mesh will prevent this to a large degree and hold it all together.

Can you lay concrete without rebar?

Asked By: Michael Kay Date created: Jun 14, 2022

It's false economy to do concrete without putting in rebar and mesh.

Rebar around the perimeter at the least, and mesh over the rest.

Pull it up when pouring so it is not resting on the bottom of the slab.

You don't need the fancy rebar supports, a stone or broken brick will work just as well..
