Retaining Wall Cost Estimator
Retaining wall planning must start with forces and water: height, length, soil, slope, drainage, loads, access, and the level of design review required.
Retaining walls hold back more than soil
A retaining wall planning range must describe height, length, slope, soil, water, access, and what sits above or below the wall. Segmental block, timber, natural stone, and poured concrete each require different preparation and drainage assumptions.
Measure the forces and the work
- Record wall length, exposed height, changes in grade, corners, steps, and the available work area.
- Document soil, excavation, base preparation, drainage, filter fabric, backfill, access, and restoration.
- Identify driveways, structures, fences, pools, vehicles, or other surcharge loads near the top.
- Keep demolition, disposal, geogrid or reinforcement, engineering, and permit work visible rather than hiding them in a material allowance.
Engineering, permits, and safety
Wall height, loading, slope, soil, drainage, property line, and local rules may require engineering or a permit. This estimator cannot determine stability or approve a design. Get qualified review before excavation or construction when conditions are tall, loaded, steep, near a property line, or uncertain; never work below an unsupported cut.
