Retaining Wall Design & Construction in the Twin Cities
When you need a retaining wall
A retaining wall holds back an embankment of soil. If your property slopes, a wall stops erosion, keeps soil from washing toward your foundation, and turns an unusable hillside into flat, functional space for a lawn, patio, or planting beds.
Built right, built to code
- Proper base and free-draining backfill so water doesn't build pressure behind the wall.
- Drainage tile — the most common reason cheap walls bulge and fail is poor drainage.
- Geogrid reinforcement tied into the slope for taller walls.
- Engineering & permits for walls over 4 feet, handled for you.

Frequently Asked Questions
How much does a retaining wall cost in Minnesota?
Most retaining walls in Minnesota cost $50–$75 per square foot of wall face installed, with typical projects running $4,000–$10,000. Cost depends on height, block type, drainage, and whether engineering and a permit are required.
Do I need a permit for a retaining wall in Minnesota?
In most Minnesota cities, retaining walls over 4 feet tall require an engineered design and a building permit. Shorter decorative walls usually don't, but rules vary by city — we confirm and handle permitting for you.
Why do retaining walls fail?
The number one reason is poor drainage. Without drainage tile and free-draining backfill, water builds pressure behind the wall and pushes it out over time.
