Depends on the size of the patio. Most can be done with only 6"X6" wire mesh.
need quote on installed concrete patio
My patio is cracked very badly. Can I get the concrete resurfaced or do I need to redo it?
Yes, a concrete patio step does in fact need to be on a footing. Without the proper footing foundation, the step will be uneven.
You still need rebar, unless you are filling a drop in an existing slab that already has steel in it.
No
Rebar is used to strengthen concrete because of its strength and flexibility. In order for these rods to work, there must be ample space between the rebar and the edge of the concrete piece.
Concrete & rebar
Our patio needs replacing. How difficult is it to construct a patio ourselves with concrete pavers?
Rebar locators are used to find exactly where the reinforcing steel is located under concrete in existing materials. They are most often used for renovation or remodeling projects.
Concrete it self may not but most concrete structures .Has rebar in them and that can .
Items used to reinforce concrete are wire mesh, rebar, and steel cables.
It depends on how much rebar you're willing to lay down, in earthquake prone areas and structural concrete you'll generally see a lot of rebar, in just normal paver concrete you may not see any. Rebar is used to give concrete flexibility without brittleness so it really depends on the use of the concrete.
