The Rock Guys of Washtenaw build retaining walls that do exactly what they're supposed to: hold ground, manage water, and look like they were always supposed to be there. We engineer every wall for your specific site conditions — slope, soil type, drainage, and load.
What a retaining wall can help solve
A properly planned retaining wall does more than improve appearance. Depending on the property, a wall may help hold back soil on a slope, create more usable yard space, replace a failing or leaning wall, support a patio or driveway area, improve drainage and reduce erosion, and increase curb appeal and property value.
Our approach
We don't believe in throwing block or stone in the ground and hoping it holds. Before any work begins, we evaluate wall height and layout, slope and soil pressure, drainage needs, access, and how the wall should relate to the home and surrounding landscape. From there, we build with attention to base preparation, alignment, drainage, backfill, and finish.

Frequently asked questions
Find answers to common questions about our retaining wall services. From materials and timelines to cost and drainage.
In some cases, yes — especially for taller or structural walls. We’ll let you know if a permit is required and help guide you through the process.
Yes. Some retaining walls are right off the driveway. Others are deep in the backyard, around tight corners, down hills, or in areas where materials need to be carefully moved in and the surrounding yard needs to be respected along the way. We account for those real-world conditions when planning the work.
If you have a failing wall, a slope that needs to be controlled, or a yard layout that would benefit from better structure and drainage, we'd be glad to take a look. We can help you determine the best approach for your property, your goals, and your budget. The free consultation is the right starting point.
A properly built retaining wall with correct drainage can last decades. The key is a solid base and proper water management, which we prioritize on every project.
Not every wall needs to be fully replaced, but many do. If a wall is leaning, separating, rotting, sinking, or failing due to poor drainage or poor original construction, we can assess whether repair makes sense or whether replacement is the smarter long-term investment. We aim to recommend what's right for the property.
Common warning signs include leaning or bowing forward, separating joints, rotting timbers, washed-out soil, cracking or shifting sections, standing water behind the wall, sinking areas, or loose caps and movement over time. If you're noticing any of these, it's worth having someone take a look before the problem gets worse.
We build with a variety of materials depending on the project goals, budget, and look the customer wants. Block walls are one of the most common — they offer a clean appearance and reliable structure across a wide range of styles. Natural stone creates a timeless, higher-end look that blends well with established landscapes. Boulder walls offer a more rugged, substantial appearance and work well for larger elevation changes or a natural landscape style. We also replace older timber walls that have reached the end of their life with longer-lasting systems.
Improper drainage is one of the biggest reasons retaining walls fail. A wall that traps water behind it builds pressure over time and will eventually lean, crack, or collapse, regardless of how good it looks on the surface. We pay close attention to backfill, drainage stone, pipe placement where needed, and how water moves through the area during and after construction.
