    I have a 3:1 slope that measures approx. 10x100. I need to cover it with 4x6 in. riprap and I am trying to figure out how many tons I will need.

    I rocked a dry creek bed and small detention pond last summer and got about 40-50 sqft per ton. Maybe able to stretch it a little depending on size of gaps between stone.

    One ton will cover 50 sq ft @ 4 in deep so I would say your in the 40-50 sq ft range also as your rock is 4-6 in.

    Timc, I have never found a formula that would work for any of the larger rock. What I do is price it by the truck load and figure in my labor, it seems to work out best for me that way.

    Thanks for your replies, I spoke with two different suppliers and they are saying 30-50sq./ton. so i think I will plan on around 40 like you guys are saying.:)
