What You Need to Know
Consultation
Choosing the right boulders for your retaining wall starts with understanding your site. That is why we begin every project with a comprehensive on-site consultation where our team evaluates the slope, soil conditions, water flow, and the overall look you want to achieve. We walk the property with you, discuss boulder sizes and stone types, and determine whether your wall needs engineered reinforcement.
During the consultation, we bring stone samples and photos of completed boulder wall projects so you can see the range of options available. We also discuss setback requirements, drainage solutions, and whether your project will need city permits or engineering review.

Stone Selection
We source boulders from quarries across Minnesota and Wisconsin, offering a wide range of natural stone options including granite, limestone, basalt, and Minnesota fieldstone. Each type brings a different color palette, texture, and character to your landscape. Our team helps you select stones that complement your home exterior and existing landscape features.
Boulder size matters for both structural integrity and visual impact. We work with stones ranging from 500 pounds to over 3,000 pounds, carefully placed with excavators equipped with hydraulic thumbs for precise positioning. Every boulder is inspected for quality before it reaches your property.

Pricing
Boulder retaining wall costs vary based on the size and type of stone, wall height, site access, and the complexity of the terrain. Natural boulder walls tend to fall in a higher price range than manufactured block, but they deliver unmatched character and longevity. Our team provides transparent, detailed estimates so you know exactly what to expect.
We work with a range of budgets and can recommend stone types and wall configurations that balance cost with the look and structural performance you need. Every estimate includes excavation, base preparation, drainage, boulder delivery, and professional placement.

Installation
Boulder wall installation requires heavy equipment, experienced operators, and a deep understanding of how natural stone behaves under load. Our crews use excavators with hydraulic thumb attachments to position each boulder with precision, interlocking stones to create a gravity wall that relies on mass and friction rather than mortar. Proper base preparation with compacted gravel and drainage fabric ensures water moves away from the wall, preventing hydrostatic pressure buildup that causes failures in Minnesota winters.
