Lay perforated drainage tubing at base Water-soaked soil is the worst enemy of retaining walls because it exerts enormous pressure behind the wall. Adding good drainage behind block or stone walls is crucial for long-lasting, bulge-free walls. Start by laying perforated plastic drainage tubing along the base of the wall slightly above ground level so it can drain to daylight. Slope the tubing about 1/4 in. per foot.
The hexagon cells that make up each COREgravel panel form a rigid honeycomb design that holds gravel in place and supports load distribution. The underside is a geotextile allowing water to drain easily and prevents weed growth. Interlocking system edges support assembly.
