Nov 22, 2008· Now you are at $60/yard. You now need 1200 lbs. of sand and the 1800 lbs of gravel, or 1 1/2 tons combined. Let's say you can buy these for $12/ton, so you're looking at $18 for this, plus delivery. So your cost is $78/yard plus delivery for the materials, plus mixing. This is much better than $180 for the sacked stuff.
