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.

What it costs

Most Twin Cities retaining walls run $50–$75 per square foot of wall face, with the average project landing $4,000–$10,000. See our full retaining wall cost guide →
