Shoreline Protection & Outdoor Solutions That Last

Rip Rap Installation & Boulder Retaining Walls in Onamia, MN

At Brainerd Boulders, we provide custom shoreline protection and erosion control services for lakefront and riverfront properties throughout Onamia. Whether you're dealing with shoreline degradation, sloped land, or preparing your lot for future projects, we offer rip rap installation, boulder retaining walls, and hardscaping and excavation services designed to protect and enhance your property.


With 50+ years of combined experience, we’ve earned a reputation as the best rip rap specialists in Onamia. Our approach is grounded in quality materials, expert craftsmanship, and a deep understanding of local terrain.


From shoreline stabilization to full-site prep, we bring peace of mind with every rock we place.

Lakefront erosion is a serious threat to landowners in Onamia — especially around Mille Lacs Lake. Our rip rap installation services use large crushed granite and fieldstone to absorb wave energy and keep your shoreline secure. Every project is graded, compacted, and strategically placed for maximum longevity. We also provide custom shoreline protection using native vegetation for those who prefer a natural, environmentally conscious solution.

If your property has slopes, drainage issues, or soil instability, our boulder retaining walls in Onamia offer the perfect blend of stability and style. Each wall is engineered with proper drainage layers and natural rock placement, ensuring long-term durability and a finished look that blends beautifully into your landscape.

We build hardscaping features that turn ordinary yards into outdoor retreats. Whether you’re adding a stone patio, fire pit, paver walkway, or boulder seating area, our team creates timeless, low-maintenance elements designed to complement your property and lifestyle.

Before installation begins, we make sure your land is build-ready. Our site preparation services in Onamia include brush and tree removal, erosion control, driveway grading, and hydroseeding. We also handle excavation for septic systems, water lines, and basement digs, giving you a stable, properly prepped foundation for construction or landscaping.

Planning to upgrade an old structure or clear space for something new? We offer light demolition services for sheds, cabins, garages, and outdated buildings. Our team also provides excavation support for utility trenches, footings, and shoreline regrading with minimal impact on your surrounding land.
