Cantilevered Retaining Walls
ENGINEERED CANTILEVERED CONCRETE RETAINING WALLS
Cantilevered retaining walls use a reinforced concrete stem connected to a spread footing to resist soil pressure through structural engineering rather than mass alone. We form and pour cantilevered walls for grade changes from 4 to 20+ feet, with engineered rebar schedules, proper footing width and depth, drainage systems, and backfill specifications. All cantilevered walls over 4 feet require structural engineering, which we coordinate.
Starting at $35 per face sq ft
Key Highlights
Engineered design
structural engineering ensures stability for heights from 4 to 20+ feet.
Reinforced concrete
rebar-reinforced stem and footing resist soil pressure through structural mechanics.
Efficient material use
less concrete than gravity walls for equivalent height.
Why Choose Our Cantilevered Retaining Walls
Cantilevered retaining walls handle significant grade changes that gravity walls can't. Our engineered cantilever walls use reinforced concrete stem walls connected to spread footings, designed by structural engineers and built by experienced concrete crews. We coordinate the full process from engineering through backfill.
Signs You Need Cantilevered Retaining Walls
1. Grade change over 4 feet
The elevation difference requires engineered structural support beyond what gravity walls can provide.
Our Process
Step 1 — Engineering
Structural engineer designs wall, footing, reinforcement, and drainage based on soil and load conditions.
Step 2 — Excavation and footing
Excavate to footing depth, pour reinforced spread footing.
Step 3 — Wall forming and pour
Form stem wall, install rebar, pour concrete, strip forms, and install drainage and backfill.

FAQs About Cantilevered Retaining Walls
Do I need a structural engineer for a retaining wall?
Minnesota building code typically requires structural engineering for retaining walls over 4 feet in retained height. Even below 4 feet, engineering is recommended when the wall supports additional loads (slopes, structures, vehicles above) or when soil conditions are challenging.
