Retaining Walls in Clackamas County
Clackamas County covers a wide swath of the southern Portland metro, from Lake Oswego and West Linn to Happy Valley, Oregon City, Wilsonville, Milwaukie, and the Clackamas area. The county's upscale neighborhoods, hillside lots, and fast-growing communities create strong demand for quality retaining walls and slope reclamation — and Oregon Retaining Walls serves it all.
Across Clackamas County we build block, natural stone, and boulder retaining walls, tiered and terraced systems, garden and seating walls, and outdoor steps. The county's sloped lots and wet winters make grading, drainage, engineering, and base prep especially important, and we build every wall to last.
From the lakeside neighborhoods of Lake Oswego to the growing hills of Happy Valley, Oregon Retaining Walls is your dependable, fully-insured retaining wall contractor. Contact us for a free on-site consultation in Clackamas County.

What Clackamas County Homeowners 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 in Clackamas County
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.
