1st Class Lawn Care and Landscaping recently installed a Rock Boulder Wall. This job was completed by using natural rock boulders found here in Iowa to create a wall to hold back soil and allow for elevation change. We used roughly 60-65 tons of boulders for this project and it took our crew 6 days complete. This particular Rock Boulder Wall had a drainage line and drainage rock added behind it by using Bedding rock and fabric to keep dirt from entering the drainage field behind the wall. At the tallest point this wall was 4.5 feet tall and 125 feet long. We used both a skid loader with a grapple bucket and a mini excavator with a thumb attachment to lift the boulders into place. Some weighted over 2 tons a piece!
