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.
