Retaining Wall Construction

Walls that hold the hill, not just the first winter.

A retaining wall does one thing: it holds back weight. When it fails, everything above it moves. Soil, driveways, foundations, sometimes structures. A properly built wall can last decades. A badly built wall can fail in a single season.

We build retaining walls for residential and commercial properties across Oregon and Southwest Washington. Everything from short landscape walls to structural walls holding back significant grade.

The right wall for your site depends on how much weight it needs to hold, how much drainage the site sees, and what look you're going for. We'll help you scope it out and make the right call.

Why Retaining Walls Fail (And How We Prevent It)

1

No Proper Base

A wall is only as stable as its foundation. We excavate properly, place compacted gravel, and set the first course level and below grade. This step alone is where most failing walls went wrong at day one.

2

Bad or Missing Drainage

Water pressure behind a wall will push it over. Every wall we build has proper drainage: gravel backfill, perforated drain pipe, weep holes where needed. Water has to go somewhere, and we make sure it does.

3

Wrong Material for the Job

We match the wall type to your site: poured concrete for structural, block for garden and mid-height, other systems for special situations. We help you make that call before we start.

4

Undersized Structure

Height, load, and slope determine the wall you need. We size the wall correctly upfront so it holds long-term instead of failing in the first big storm.

5

Sloppy Finishing

A retaining wall is often visible from your house. We finish clean lines, proper caps where they belong, and integrate the wall with the surrounding landscape.
