3 - Retaining Walls: These are used to stabilize steep banks which control soil movement. Water that is allowed to collect behind the wall can exert pressure causing the wall to move. Drainage provisions are often not evident with a visual evaluation. Sometimes efflorescence (a white powdery substance) is present on the wall due to no or blocked drainage. Retaining walls should appear straight or tilt slightly toward the earth they support. Walls that are cracked or leaning will need structural evaluation and repair.
