What is the price of concrete for a 22.5 foot by 24.5 foot slab?
That depends on if you get a 4 inch or 6 inch slab. A 4 inch slab will use 7 cubic yards of concrete, and a 6 inch slab will use about 10.5 cubic yards. The price of concrete varies from place to place. I would guess about $75 per yard as a ball park figure. $525 to $800. You need to figure re bar, framing, sand, labor, and prep work. $1,500 to $2,250 for the basic job done right. Prices are going up every day due to the cost of fuel. Prices vary according to your area. In NY or CA the price could be 3 to 5 times what I estimate.
