Estimate How Much Concrete You Need

Concrete Calculator

To use the Concrete Volume Calculator, simply choose a shape and then enter the width, length, and thickness of your pour. The calculator will automatically estimate the number of cubic yards of concrete that will be required. Concrete is ordered by volume in cubic yards.

NOTE: This Calculator should be used as an estimating tool ONLY. CSC is not responsible for any discrepancies in material based on calculations made with this application.

Tips For Ordering Concrete

Measurements can frequently be a little off, so we highly recommend ordering a little extra, because coming up short can be a disaster.  A good rule of thumb is take your calculation and add 4% to 10% to the total to account for waste, spillage, over-excavation, settlement, spreading of forms, loss of entrained air or any other changes in volume.  Concrete can be ordered in ½ yard increments.

Slump is a measure of the consistency of the concrete.  A 4 inch slump (the measure of the distance a wet concrete cone will fall) is typical.  If you want more slump, it is always safest for the concrete to adjust slump at the plant.  Adjusting slump at the job site will damage the concrete.  Adding just 1 gallon of water per cubic yard can decrease compressive strength 150 to 200 psi, waste cement and increase shrinkage by 10%.  This is especially a problem for concrete that might be exposed to freezing and thawing conditions.

Strength is most commonly measured by the designed compressive strength in pounds per square inch (psi) of a hardened cylinder of concrete. Any slab exposed to freeze-thaw conditions should be a minimum of 4,000 psi.

Entrained air is little bubbles of air primarily to increase the durability of the hardened concrete to freeze-thaw conditions. Any exterior slab in our climate should have air entrainment.

Do you need aggregate (stone or gravel) for the project? Do you have the concrete tools that you need? Our professional customer service representatives and our Concrete Store Representatives can help you make sure you are prepared, just call 704-372-2930.

You will need to provide a washout area for the truck after it is finished pouring the concrete. This should be a contained area that would not allow liquids to seep into surrounding areas. A wheelbarrow or other container is often the easiest to supply.
