Concrete Pricing?

Here is what I want to accomplish. Right now I have a 30×50 shop with a gravel floor. Because it is built on a downslope the last 15 feet is walled off and the floor is about 3 feet lower than the main shop giving me a 15×30 room. I would like to make this into a hockey training area for my boys to shoot pucks, lift weights and what not. Any ballpark for cost on what this would cost to pour? Maybe pricing to have someone do it all and a ballpark if I did it all myself. I’m not a concrete guy buy I have friends and know how to buy beer.
Thanks, DT

There is 9 Square feet in a Square Yard. 3 Feet X 3 Feet. There is 27 Cubic Feet in a Cubic Yard. 3 Feet X 3 Feet X 3 Feet. Is the Concrete 4″, 5″, 6″ so on? The formula is the same.

A cubic Yard of Concrete will cover 54 Square Feet of 6″ thick concrete. $100 per yard 100/54. Would equal about $1.85 per Square foot.

The Formula is: Inches thick/12″. ie. 4″/12″ or 6″/12″. Then take 27 and divide it by the number you get. ie 27/.5(or 6″ thick of concrete) Equals 54 square feet of 6″ thick concrete. Then divide the price of Concrete per cubic yard by the square feet of what you got. ie $100/54 Equals $1.85.

Example for 4″ thick Concrete
Cubic Yard of Concrete = $100.00

4/12 = .33
27/.33 = 81.81
$100/81.81 = $1.22 Per square foot of material.

Prices may have gone up.

The way I figured it you would need 5.5 yards of concrete to do the hockey area if it is 4 inches thick. If you did the rest of the shop you would need 19.33 yards if 6 inches thick or almost 13 yards if 4 inches thick. You should probably use some rebar, especially in the shop part which adds to the cost.

definitely use some re-bar.
but lots of differing opinion about the fiber reinforced concrete.

Probably cost between 5-6 bucks a sq ft to have some one pour it.

you would be hard pressed to find concrete for 100$ a yard. I would think 150$ would be more like it. I would use number 3 or 4 rebar at two foot spacing with a two foot over lap. chair them up with 1.5 inch patio pavers as to keep rebar elevated while placing. saw cut the floor 1/3 depth of the concrete. Say 10ft by 7.5ft if just doing end of shop. After slab is sawed soak down with water and cover with poly, reapply water to keep wet. leave poly on for 7 days. let dry and apply a good sealer. brock white has a number of them. best of luck.

If you did the whole shop at 4″ thick, you are looking at about 19 yds. of crete, but you do NOT want to short yourself, so order a little more. You’re looking at a good $2000.00 just for crete. Use plenty of steel,both rebar & wire mesh. Mesh the entire floor!! The floor WILL eventually crack, & you do NOT want it to move. Then you will need 4″ felt expansion joint for the entire perimeter. You will also need to add in a sand lift to bring everything to grade and tools & labor. Just some thoughts. Good luck with everything.

I would use class 5 for leveling and base. Definitly use mesh. Also look into fibercrete

Wire mesh sucks, use rebar and fiber mesh in the concrete. The fiber will do the same thing as the wire mesh but, you won’t be tripping over it hoping that it got pulled up.

Wire mesh is always found on the very bottom when I tear out old concrete.
