About Hillsboro
Retaining Walls in Hillsboro, OR
Hillsboro sits on the floor of the Tualatin Valley, so its grade changes tend to be gentler than the West Hills — but that doesn't mean walls are optional. Much of the new construction around Orenco Station, Witch Hazel, and South Hillsboro cuts building pads into gentle slopes, and those cuts need proper retention, terracing, and drainage to stay stable and usable.
Valley-floor soils here hold water. Silty clay with a high winter water table means drainage is the single most important part of a Hillsboro wall — gravel backfill, perforated drain pipe, and correct grading matter more than the block you choose. We build the drainage first and the face second, which is why our walls don't bulge after a wet February.
We work throughout Hillsboro, from established neighborhoods near downtown to the newer subdivisions on the south and west edges, building garden and seating walls, tiered systems, and outdoor steps. Contact us for a free on-site consultation in Hillsboro.

“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 Hillsboro
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.
