How Much Concrete Do you Need?

 

 

 

 

Step #1

How big is your Pour?

Determine how many square feet your project will be.

Example: a new sidewalk 20 ft long x 4 ft wide = 80 sq ft

 
Square Feet of Concrete

1 1 2 4 8 10 15 20 25 30 35 40 45 50
2 2 4 8 16 20 30 40 50 60 70 80 90 100
4 4 8 16 32 40 60 80 100 120 140 160 180 200
8 8 16 32 64 80 120 160 200 240 280 320 360 400
10 10 20 40 80 100 150 200 250 300 350 400 450 500
15 15 30 60 120 150 225 300 375 450 525 600 675 750
20 20 40 80 160 200 300 400 500 600 700 800 900 1000
25 25 50 100 200 250 375 500 625 750 875 1000 1125 1250
30 30 60 120 240 300 450 600 750 900 1050 1200 1350 1500
35 35 70 140 280 350 525 700 875 1050 1225 1400 1575 1750
40 40 80 160 320 400 600 800 1000 1200 1400 1600 1800 2000
45 45 90 180 360 450 675 900 1125 1350 1575 1800 2025 2250
50 50 100 200 400 500 750 1000 1250 1500 1750 2000 2250 2500

Step #2

How deep is your Pour?

Using the same numbers from above, use the 4" or 6" chart to determine how many cubic yards of concrete you need.

Example: the 80 sq ft sidewalk from above, at 4" thick would take .99 cu yards, order
