Retaining Walls

These guides explain how base trenches, drainage stone, backfill, and setback affect stability, and how to plan short garden walls built from interlocking blocks. They also describe the warning signs of leaning or bulging, and they make clear when height, slope, or nearby structures mean you should consult an engineer or licensed builder.
