Do I need a permit to build a retaining wall in Elk River?

It depends on the height and location of the project. In Sherburne County, retaining walls over 4 feet tall—or any hardscaping built directly along shorelines or wetlands—typically require a building permit and an engineered site plan. We understand the local zoning codes and can assist you in navigating the permitting process so your wall is fully compliant and structurally sound.

Why do you use natural boulders instead of timber walls?

Timber walls eventually rot, and small, lightweight decorative blocks often fail against the immense pressure of Elk River's heavy clay. We utilize massive natural fieldstone and heavy-duty engineered blocks because they offer unmatched longevity and structural weight. Because we own the heavy excavators necessary to move these massive stones, we can build a barrier that permanently stabilizes your slope without the risk of future decay.

How do you prevent winter frost heave from destroying the wall?

Hydrostatic pressure—weight from trapped water—is the number one cause of wall failure in central Minnesota. To combat this, we over-excavate the dirt behind every wall we build. We install heavy-duty perforated drain tile at the base and backfill the entire cavity with clean, washed aggregate. This ensures that ground moisture drains away immediately, protecting your investment from winter freeze-thaw expansion.
