    Im in a need of a little help! I was wondering what kind of calculations everybody uses for determining the tonage of boulders needed for a retaining wall? Is there a way with sq. footage x something? THANK YOU Cory

    Hey bud,

    When ever I build boulder walls, I usually use basketball size boulders to build them. The formula they always taught us in college is that using that size boulders, one ton of boulders will build a wall approx. one foot high and twenty foot long. You can use that but I always figure it based on one foot high and fifteen feet long. I usually end up rite on the money when I use that. If anything it will allow you a little extra too. Cause you always have boulders left over.
