    Default Raising Carport Concrete Floor

    We inclosed our carport and took out the wall between the living room and carport. Now I would like to raise the carport floor to match the living room floor with concrete. The carport floor has a slops from 2 1/2"-4". We live in AZ so it is dry and hot here. Any ideas on how to do this?

    What type of floor is in the carport now? If it is just stone I would get some prices on a concrete floor and keep it low enough so the finished floor is even with the living room floor.

    You don't say how much difference in elevation there is between the carport and the living room. If the carport slab is in good condition (not all cracked), you could pour concrete over the top of it.

    If you're talking about 6-8 inches difference in elevation, you may want to put a form around the carport and fill it with clean dirt and compact it so you have enough room for 3-4 inches of concrete. It will be cheaper than filling it all the way with concrete. That way you can make the slabs equal in height and have a smooth transition between the two spaces.

    Good Luck.

    The carport is concrete and in good shape. The living room drop off is 2" and to the far end it tapers to 4". So it has a slop that starts at 2" lower than the living room and ends at 4" in the corner. Do we have to put anything on the carport concrete before we pour more concrete on top?

    You might want to look into a bonding agent from your local cement batch plant. Usually, 2" of concrete poured on top of already seasoned concrete will crack because the old concrete expands and contracts at a different rate. The bonding agent material can tell you what will work and what won't. Hope this helps.

    Not a good idea to pour new concrete over old, you should either tear out the old floor and pour new concrete or you could build a wood floor over the existing floor.
    HOPE THIS IS HELPFUL!
