How large of area will 6 tons of 1" gravel cover ?

That is a truck load, I assume, well how big is your driveway, and did you do the math before you ordered the truck ?

So... you tell me how big your driveway is in square meters and I will tell you how much gravel you will need to cover, assuming it is to a depth normally used before paving.

One ton covers 100 s/f 2" deep. Try this for accurate info. Order gravel
