Ready-mixed concrete is marketed by volume measure up in cubic yards. If you have the right to determine the area of your concrete task (length x broad for rectangular projects) and know the thickness that the slab, you can use the information in the Concrete Volume Calculator listed below to determine just how much concrete friend need.

You are watching: 1 yard of concrete covers how many square feet


One Cubic garden of Concrete:

4-inches special – covers 81 square feet5-inches thick – consist of 65 square feet6-inches thick – consist of 54 square feet7-inches special – consists 46 square feet8-inches special – consist of 41 square feet10-inches thick – consists 32 square feet12-inches thick – consists 27 square feet.

For example, let’s calculate just how much concrete is essential for a 5-inch thick rectangle-shaped driveway, 60-feet lengthy (length) and 18-feet vast (width). The area the the driveway is 1,080 square feet (60-feet x 18-feet). According to the table above, one cubic garden of concrete put at a thickness the 5-inches covers 65 square feet. In a perfect universe, ours 1,080 square foot driveway will need specifically 16.62 cubic yards the concrete (1,080 square feet / 65 square feet equates to 16.62 cubic yards).

But project sites room not perfect, and also batch tree cannot produce concrete to together exacting volumes. To allow for spillage throughout placement, kind movement, uneven subgrade, and consolidation, most building contractors order 10% to 15% an ext concrete 보다 the computed volume because that the forms, and round as much as the nearest 4 minutes 1 yard. In our example 16.62 cubic yards x 105% = 17.451 cubic yards. Rounded as much as the nearest quarter yard, we would certainly request 17.5 cubic yards the concrete once ordering concrete because that the project.

For irregular-shaped pavements and also slabs, produce a scale drawing of the project. Divide the rarely often rare shape right into a series of continual rectangles and also determine the area because that each rectangle in the series. Use the table over to calculate how many cubic yards the concrete would be necessary for each rectangle in the series. Add the cubic yard quantities of every rectangle in the series, multiply by 105%, and round approximately the nearest 4 minutes 1 yard.

For radius work, sketch a rectangle approximately the radius area and use the length and also width the the rectangle to estimate the square footage of the radius area.Use this calculator from to estimate how much concrete through volume you’ll need for your next project. Click right here >

Our task Associate will certainly be happy to help you figure out how much concrete girlfriend need. Call Jeff Madsen in ~ 414.831.2458. But prior to you contact to inquiry help, measure her project and also create a scale drawing, finish with the really dimensions.

By measuring her project, producing a project scale drawing, complete with the actual task dimensions, and doing the area and volume calculations yourself, you carry out one last chance to make certain you have actually taken all facets of the project right into account prior to placing your concrete order. This minimizes the possibility you will run quick of concrete and need come order a “clean-up” load, i m sorry includes added delivery and often minimum fill charges.

Once friend have established how lot concrete your project requires, contact SRM Concrete Dispatch at: 414.831.2404 to set up a time and also date for concrete delivery.
