how much sq ft. per ton

[scrib]

I have a couple jobs where they would like limestone outcroppings. I can not figure out how many ton I will need. The outcroppings vary in size, anywhere from 5" - 10" thick, 20" - 48" wide and 24" - 60" long. I have one job that needs a wall and another that is looking for steps. The only pricing I have is per ton and can not figure how to get a good idea on cost for them. The wall is about 6ft tall and 16ft long. The steps will go about 40 ft down a hill.
Thanks for any help.

For the steps, I just try to find rocks that are about 7-8 inches thick. I count one per step. If they are big rocks,
i set them back into the hillside under the next step

Hope that helps,

The walls are tricky, You have to guess at what will be the face side of each rock and visualize it, It always takes me two trips to the supplier

ok, what would you charge to install about 40 steps in an existing landscaped area. Do you figure 1 step per ton?
