How Much Concrete Does It Take to Fill in a approved Driveway?

One of the first steps in figuring out how much concrete is needed in a thorough driveway is to define "standard". Concrete is measured in cubic yards and to have an accurate estimate of concrete requires you to know indeed how many square feet of covering area you are covering as well as the depth desired. So for the sake of this record we will say a thorough two car driveway is 20'x20' or 400 square feet. Typically unless requested to be thicker by the homeowner contractors pour driveways 4" thick. So for figuring concrete in this example we would take the square footage and multiply it by the decimal percentage of 4"/12" to get our cubic footage and then transfer it to cubic yards. So 400 x.33 = 132 cubic feet. Now we want to change our cubic feet into cubic yards so we know what to order from the plant. There are 27 cubic feet in one cubic yard so we would take 132 and divide by 27 giving us 4.89 cubic yards needed.

Now we know we need 5 yards to do the job but in this example five yards is barely sufficient so it is recommended to order one more yard to be safe. So for a thorough 20' x 20' two car driveway we would need 6 yards to do the job and not run out of concrete. Figuring how much concrete is needed is only half the battle, concrete used in driveways must be reinforced and also consist of the right combination of Portland cement to hold up to the demands unbelievable of it as a driveway. Concrete is a very versatile building material that will create years of maintenance free aid as long as it is place correctly and reinforced. Concrete has big compressive drive but dinky to no tensile strength, development it a good material to drive on but it must be reinforced with steel to keep from cracking and arrival apart. So in the business it is thorough for a five sack mix or 3000 psi combination with 3/8" or #3 rebar to be settled on 18" centers both ways ensuring that the rebar is exactly in the middle of the concrete to be effective. So figuring concrete and rebar for any project is just as easy, remember to figure square footage first then multiply by the decimal percentage of how thick you need it to be and divide by 27. Now you know how to effectively figure yards of concrete for your next project.
