How Do You Calculate Concrete Yards For Curbs & Gutters?
Concrete is often used to construct curbs and gutters by filling trenches with concrete to create them. Concrete is sold by cubic yards; so when calculating how much concrete you need to purchase for a project, you must find out how many cubic yards you need. You can do this by finding the area to be filled in feet and then converting that measurement to yards. Know that the formula for calculating concrete is the following: ((Length X Width X Height)/27) X 1.05 = Total concrete needed plus 5% extra. The length, width and height are measured in feet and then divided by 27 to convert the cubic feet to cubic yards since concrete is sold in cubic yards. The figure of 1.05 is included because it is usually recommended that you purchase 5% more concrete than what you need. Measure the length, width and height of the trench to be filled to create the curb or gutter. For instance, in this example, let’s assume that the length of the curb or gutter is 100 feet, the width is 5 feet and the heig
