Engineered to Last
Retaining Walls.
Structural walls that solve real problems -- erosion, grading, usability -- while adding dramatic beauty to your property.
Structural walls that solve real problems -- erosion, grading, usability -- while adding dramatic beauty to your property.
Every spring in Southeast Michigan, the same story plays out: the snow melts, the rain comes, and another chunk of your yard washes away. That slope behind your house in Shelby Township keeps getting steeper. The hill along your driveway in Clinton Township is slowly collapsing. The grade next to your foundation in Sterling Heights is pushing water exactly where you don't want it.
Erosion is a slow-motion emergency. It gets worse every season, and the longer you wait, the more expensive the fix becomes. A $15,000 wall this year becomes a $30,000 wall next year when the soil shifts further, the drainage fails, and the problem doubles in scope.
Beyond erosion, you're losing usable space. That sloped backyard could be a flat patio, a play area, or a tiered garden. A properly engineered retaining wall doesn't just stop erosion -- it transforms unusable land into your favorite part of the property.
A retaining wall is only as strong as what you can't see. That's why every Nelligan's wall starts with engineered base preparation -- compacted gravel, geogrid reinforcement on taller walls, and integrated drainage systems that channel water away from the structure.
We use premium Unilock and Belgard wall systems rated for structural loads, not the thin veneer products that look good for a year and lean by year three. Our walls are designed to handle Michigan's brutal freeze-thaw cycles without cracking, shifting, or failing.
From 2-foot decorative garden walls to 8-foot structural monsters that reshape entire properties, we've built them all. 25+ years, 500+ projects, and a 4.9-star rating from homeowners across Macomb, Oakland, and Wayne Counties.

SCHEDULE FREE ESTIMATE →If you have a slope that's eroding, water draining toward your foundation, a hillside that's difficult to mow or use, or you want to create level areas in a sloped yard -- you need a retaining wall. We offer free site assessments to evaluate your specific situation.
In most Southeast Michigan municipalities, walls over 4 feet in height require a building permit and potentially engineered drawings. We handle the entire permit process for you -- it's part of our service.
A properly built segmental retaining wall with adequate drainage should last 50+ years with minimal maintenance. The key is proper base preparation and drainage -- which is exactly what sets us apart from budget contractors.
The #1 cause is poor drainage behind the wall. Water builds up hydrostatic pressure that pushes the wall forward. The #2 cause is inadequate base preparation. We address both issues on every single project -- no shortcuts.
