Retaining Walls
Boulder & Rock Retaining Walls in Portland, OR
Boulder walls — sometimes called rock walls or rockeries — hold back slopes with big, natural stone and a bold, rugged look that suits Pacific Northwest landscapes. They're a great fit for larger grade changes, erosion control, and properties where a softer, more organic appearance is the goal.
Building a boulder wall right is heavy, precise work. We set each boulder on a compacted, well-drained base, key the stones together and batter the wall back into the slope for stability, and build in drainage behind the face so water moves through instead of pushing the wall out. Sizing and placing each rock takes equipment and experience — both of which we bring to every project.
Boulder walls pair beautifully with natural plantings and stone steps, and they can be tiered up a hillside to reclaim usable space. We handle the excavation, drainage, placement, and finish grading for a wall that looks natural and performs for decades.

What Our Clients Say
“Oregon Retaining Walls rebuilt a failing timber wall in our backyard with a beautiful tiered block wall. The crew was professional, on time, and you could tell the drainage and base work was done right. Best contractor we've worked with in Portland.”

“We had a natural stone retaining wall and matching steps installed and could not be happier. They took the time to get the design exactly right, and the craftsmanship is top notch. Turned a useless slope into our favorite part of the yard.”

“Needed a tall engineered block wall to hold back the hillside above our driveway. ORW handled the engineering and permits, built in the drainage and geogrid, and it passed inspection with no issues. Clean work and great communication start to finish.”

“Our new boulder wall and stone steps completely transformed the front of the house and stopped the erosion we'd been fighting for years. The install was fast and clean, and it looks fantastic. Thank you Oregon Retaining Walls!”

Our Process
How We Work
Free Consultation
We meet you at your property to walk the slope, learn your goals, and talk through wall style, materials, height, and budget.
Design & Engineering
You get a clear design and a detailed written estimate covering material, height, drainage, and reinforcement — engineered where the height or load requires it, so you know exactly what to expect.
Excavation, Base & Drainage
Our crews excavate and compact an engineered gravel base, set a level leveling pad, and build in drainage — perforated drain pipe and clean gravel backfill — the parts that keep an Oregon wall standing for decades.
Build, Backfill & Finish
We set each course level and true, add geogrid reinforcement where needed, backfill and compact in lifts, cap the wall, and clean the site — then walk the finished project with you.
