To be effective, steel reinforcing materials should be placed in the bottom half of the countertop slab. Sufficient concrete cover is required to prevent corrosion and rust stains. Pro tip: Don't use rebar to reinforce countertops that are less than two inches thick.

Can you lay concrete without rebar?

Asked By: Lovekesh Kumar Date created: Jun 21, 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..
