How thick does concrete need to be to not crack?

To prevent load-stress cracking, make sure a slab is built over a uniformly compacted, well-drained subgrade, and is thick enough to withstand the kind of use it will get. In residential concrete, 4 inches is the minimum thickness for walkways and patios.

What is the minimum thickness for a concrete floor slab?

What kind of dirt do you use for a house pad?

Do you need gravel under concrete?

You do need gravel under a concrete slab, footing, or patio. Gravel provides a solid foundation for your concrete as it can be compacted. It also improves drainage, preventing water from pooling beneath the concrete.

Should I put wire mesh in concrete slab?

Concrete Wire Mesh Helps Minimize Concrete Slab Cracking and Settling. In fact, the best way to minimize the chance of cracking and settling is to use fiber mesh and WWM in the same slab. Like any structural product, WWM won't do its job unless it's installed correctly.

Can I use chicken wire to reinforce concrete?

Chicken wire or wire mesh can be safely used as a reinforcement in concrete when the concrete is not used in structural or high-weight areas. The wire mesh or chicken wire can add stretching strength that concrete does not have, giving the concrete rigidity when facing specific pressures.

How many yards of concrete do I need for a 24x24 slab?
