PWC’s grade changes and clay make retaining walls a drainage problem wearing a masonry disguise.
Our method
Base course below grade on compacted stone, drainage aggregate and perforated pipe behind every course, geogrid where height demands it, and batter (lean-back) built into the stack. Walls over permit height get engineered drawings — no exceptions.
Images are illustrative — project photography from our completed jobs is being added. Every method described here is exactly how our crews work.
