Can anyone tell me if outdoor front entrance concrete stepsand garage floors ALWAYS have rebar in them? If these above components are in colder climates do they ALWAYS have rebar in them?

Having worked on new and reno homes for years we never poured a garage floor or basement without steel mesh, usually 4" squares, just for strength alone. I am sure there are contractors who don’t do this but I my opinion it never hurts to over build.

No, rebar is not required. Garage floors are poured last. Generally the thickness is usually about 4" minimum plus. Many builders will not use rebar, nor do many provide control cuts. And nor do they always provide a proper bed for the concrete to be poured on. That is why it is not uncommon to see cracked and heaved slabs in garages.

ALL concrete requires reinforcement. Concrete has compression strength only and no tensil strength. All slabs require either steel, fiberglass or the newer nylon bars. Want code cites?

Jeff,


Not in Ontario. Even concrete floors in basements are not poured with rebar or mesh. Of course there is nothing to prevent one from upgrading and requesting rebar before pouring.

Raymond,


I know they do not do it in the field. I did not do it in Winepeg, or Ft. Frances when I built there. I do believe that the Canadian Code requires it in the refferenced specs though, does it not?

Raymond,


I cannot remember, does the Canadian Code have a chapter on Standards like we do. ASTM standards for instance? That is where it sould be found, if it is in there.

Hi Jeff,


I believe there is a standard, but I haven't found that yet either. I am using the Ontario Building Code on CD, I will search through it and look for the ASTM, I am sure its in there somewhere.

Jeff,


Your statement "ALL concrete requires reinforcement" is not always true, what about Curb & Gutter, Sidewalks, Basement Foundation Walls for Homes, equipment pads and the list can go on for other concrete applications.

Your statement "Concrete has compression strength only and no tensile strength" is true, but tensile strength is usually a measurement for metal.

Your statement "All slabs require either steel, fiberglass or the newer nylon bars." is not true, it depends on the load that the concrete will carry and the compacted fill under the slab.

I believe that your term of "steel" is for rebar or reinforcing bar. I have never seen or heard of "newer nylon bars" , I think you might be calling epoxy-coated reinforcement bars as "newer nylon bars".

KERRI

The answer to your question is NO for slabs and NO for concrete steps.

Jeff;

Raymond is right and saved me the leg work of the research. Thank you Raymond.

Jeff; here in Maine, it is an option to elect to reinforce your steps or garage floors, most residential homes unfortunately do not have reinforcing bars nor wire mesh. The IRC Code is the bottom line here.
You will not get more than that unless specified by an Architect or the owner himself.
I would strongly recommend that anyone building a house at least install a wire mesh in their garage floors. Usually it would be a 6"x6"x #10 or 2.2 if I am correct.

Installing reinforcement bars would be my preference, but usually never occurs. If it does, I would recommend 1/2" bars at every 2' center each way.

No wire mesh, no reinforcement, use fiber mesh at the very least.
