Most of the cost of a driveway, patio, or other residential project requiring poured concrete is the cost of pouring concrete itself.
You can calculate concrete prices and how many cubic yards of concrete you’ll need for your project to help anticipate the final cost of pouring concrete.
Calculating Your Needs
Concrete is usually priced by the cubic yard, but you might not know what your project is in yards. Convert it from feet using the following steps:
- Figure out the length, width, and depth of your project. Depth might be harder to figure out, so for your calculations, you can use 4 inches. This is the standard concrete thickness for residential construction. To make it simple, we’ll use an example of 10’ x 10’ with 4 inches of depth.
- Multiply the length by the width to get the square footage; per our example, 10 x 10 = 100.
- Change the depth from inches to feet. It’s easy to Google, but for those who like mental math, 1 inch equals 0.083 feet. This means 4 inches is 0.33 feet.
- Multiply the thickness by the square footage to figure out the cubic feet; 100 x 0.33 = 33 cubic feet.
- Multiply this by 0.037 to convert cubic feet into cubic yards. 33 x 0.037 = 1.22 cubic yards.
You should add an extra 10-15 percent to your final number. This will help you account for variations in the slab depth and spillage.
The Strength Of The Mixture Affects the Cost of Pouring Concrete
Concrete can vary in price based on the necessities of the project. By contacting the supplier and telling them your project, they can advise you on the best proportion of cement, aggregate, and sand to use. This proportion will determine the strength and durability of the concrete when it goes up against the elements. In Ontario, where freezing and thawing can be very cyclical, you might want to choose air-entrained concrete. This concrete has air pockets in it to relieve internal pressure that can come from water expanding when it freezes.
The mixture can impact the pounds per square inch (PSI) of a project. Home projects should be between 2500 and 5000 PSI, but it all depends on what the concrete is being used for. For example, a concrete walkway will be 3,000 PSI, but this will also change for different effects. The PSI of the concrete used as the base of a small building like a shed will be different from the concrete used in a patio. These will be different from the concrete used than an exposed aggregate walkway.
