Retaining Wall Contractor in Astoria, OR

Hillsides define Astoria, and so do the retaining walls that hold them in place. As a retaining wall contractor in Astoria, OR, Alejos Construction & Landscape builds and repairs walls that deal with saturated soil, steep grades and the weight of the slope above them.

Building in Astoria, OR

Astoria climbs from the Columbia River waterfront up steep hillsides, so a lot of yards here are sloped, tiered or squeezed behind older homes with tight access. Rain falls most months of the year, and hillside soil stays saturated well into spring.

Wet clay behind a wall is heavy. Most of the failed Astoria walls we see are not bad because of the material but because water had nowhere to go behind them.

Drainage is half the wall

A wall is more than a stack of blocks. We start with a level, compacted base below the wall, build the face with a slight setback, and backfill with clean drainage rock and a perforated pipe that carries water to daylight. Taller walls get geogrid reinforcement tied back into the slope. Without this structure, water pressure builds up and the wall begins to lean.

Wall types we build

• Segmental block walls for most residential heights.
• Natural stone walls where appearance matters.
• Tiered walls that turn a steep yard into usable terraces.
• Repairs and rebuilds of leaning or bulging walls.
• Wall height, nearby structures and what sits above the wall determine whether you need engineering, so we raise that question at the estimate.

Permits and local rules

Tall retaining walls and walls that support structures or roads generally require permits and engineering. City of Astoria Community Development can confirm the height threshold and any other rules for your address, and we raise it up front at the estimate. We do not replace local officials, and we never guess about code.

Warning signs we are called about

Leaning faces, bulging bottoms, cracks in the cap and water running out of the wall face are all signs of pressure from trapped water. A wall that has moved once will keep moving unless the cause is solved. In many Astoria yards we find no drain pipe behind the wall at all, or one that has silted up. Repairs often mean rebuilding the wall properly rather than propping it, which we explain honestly at the estimate.
