Boulder Wall Services We Provide
Large Boulder Wall Placement
We place and position large granite boulders (2–10+ tons) using heavy excavation equipment to build stable, load-bearing retaining walls. Suitable for steep slopes, lakefront properties, and high-load commercial applications.
Stacked Boulder Wall Building
Carefully stacked and fitted boulders create structurally sound walls with a natural aesthetic. Each stone is selected and positioned to interlock and distribute weight evenly — no mortar required.

Frequently Asked Questions
How long do boulder retaining walls last?
Properly installed granite boulder walls last 50–100+ years with minimal maintenance. Natural stone does not rot, rust, or deteriorate like timber or steel alternatives.
Do boulder walls require drainage?
Yes. We install gravel backfill and drainage pipe behind all boulder walls to relieve hydrostatic pressure — a critical step that prevents wall failure and extends the wall's lifespan.
What size boulders do you use?
We work with boulders ranging from 500 lbs to 10+ tons depending on wall height and load requirements. Our heavy equipment fleet handles placement of any size.
Do I need a permit for a boulder retaining wall in Minnesota?
Permit requirements vary by municipality and wall height. We advise clients on local requirements and can assist with permit applications for walls over 4 feet in height.
