Experienced
As one of the most experienced retaining wall companies in the upper Midwest, we can confidently install natural stone, boulder and modular block retaining walls in a variety of landscapes.
Large or Small
We have built both modular block and boulder walls over twenty feet tall in many communities around the Twin Cities, for both large commercial and small residential jobs.
Engineered and Built to Last
We work extensively with a licensed geo-technician and civil engineer that provides us with stamped, certified plans specifically designed for each site.

New or Repair

We not only install new retaining walls, but we also repair existing retaining walls that may be failing, damaged or both.

Built Right

Many contractors take the typical “stack the stones" approach. At Dirt Monkey Inc, we realize there is much more to it than that. Water drainage, grading, and soil compaction all play large role in the quality and longevity of your wall. Every single one of our project leaders has taken classes on soil dynamics and geo-grid reinforcement techniques in retaining wall applications.
