We loved our experience with Rhino! Communication was quick and clear. We were able to get a no hassle estimate and scheduling with the team was easy. They were able to get out to our house quickly and did great landscaping work!

We hired Rhino to do our front and backyard. My husband and I are really happy with how it turned out. The yard looks great now and the kids love having a place to play and hang out.

Denis did a great job and was very conscientious about the details. The weather was horrible, but he came out regardless and braved it like a trooper. Pricing was more than fair and I will definitely be using them again.

Our Process

What to expect with your retaining wall

  1. 1

    Free On-Site Estimate

    We walk the slope, check the grade and where water runs, measure the wall, and help you pick the block style and color.

  2. 2

    Layout & Excavation

    We mark the wall line, then dig a level trench and cut the slope back so the wall sits on solid, undisturbed ground.

  3. 3

    Compacted Base

    We build and compact a crushed rock leveling pad. A flat, solid base is what keeps a wall from leaning or settling, so we never skip it.

  4. 4

    Drainage & Backfill

    We set drain rock and a drain pipe behind the wall so Pacific Northwest rain drains out instead of pushing against the blocks.

  5. 5

    Setting Block & Reinforcement

    We lay each course level and locked together, and add geogrid reinforcement into the soil on taller walls so they stay put for the long term.

  6. 6

    Caps & Cleanup

    We secure the capstones, finish the backfill and final grading, and clean up the site before we leave.

FAQ

Common questions about retaining walls

Why do retaining walls lean or fail?

Almost always weak base prep and no drainage. Water building up behind a wall is what pushes it over. We compact a proper base and build in drain rock and pipe so water has somewhere to go.

How tall can a retaining wall be?

Lower garden walls are straightforward. The taller a wall gets, the more soil and water it holds back, so above a certain height we add geogrid reinforcement, and some walls need an engineer's design or a permit. We tell you up front what your wall needs.

Do I need a permit for a retaining wall?

It depends on the height and your city or county. Shorter walls usually do not, taller ones often do. We sort this out during planning and let you know before any work starts.

What blocks do you use?

We use engineered segmental retaining wall blocks that interlock and step back slightly with each course. They come in several colors and textures, so the wall matches your home and your other hardscape.

Can a retaining wall help with drainage and erosion?

Yes. A wall built with proper drainage holds back the slope, keeps soil from washing into your yard, and moves water away from the area you want to keep dry.

How long does a retaining wall take to build?

Most residential walls take a few days to about a week depending on length, height, access, and weather. We give you a clear timeline with your quote.
