Retaining Walls in Highland Park

Expert Retaining Wall Construction & Repair

In Highland Park, a retaining wall is often the only thing standing between a backyard and the street below. From the steep grades of the Garvanza district to the slopes bordering Mt. Washington, this neighborhood is defined by gravity. Unfortunately, it is also defined by aging infrastructure—unreinforced river rock walls from the 1920s, leaning concrete blocks, and rotting railroad ties that have long outlived their lifespan.

When these walls fail, they rarely do it quietly. A bulging or leaning wall is a structural threat to your home, your neighbor’s property, and the public right-of-way. Replacing them requires more than a landscaping crew; it requires a structural engineer who understands the specific soil pressures and slide risks of Northeast Los Angeles.

Retaining Wall Contractors Highland Park

Many homeowners in Highland Park assume a general contractor or a mason can swap out a failing wall. But in Los Angeles, any retaining wall over 36 inches (or one supporting a "surcharge" load like a driveway or hillside) requires a permit and a stamped engineering plan.

If you hire a standard contractor, the process is fragmented. They hire an outside engineer, who hires a soil consultant, and you are stuck managing the delays.

Alpha Structural eliminates that gap. We are the only foundation contractor in Los Angeles licensed to engineer and build in-house. We don't guess at the reinforcement needed. We analyze the slope, calculate the load, design the wall, and build it with our own teams.

The Alpha Standard for Hillside Walls

We do not build temporary garden patches. We build permanent structural assets.

• Concrete & Shotcrete Walls: High-strength solutions for steep or limited-access sites.
• Caisson-Supported Walls: For slopes with deep active soil zones, we drill steel-reinforced piles into bedrock to anchor the wall permanently.
• Permit Handling: Highland Park (City of LA) has strict grading and hillside ordinances. We handle the engineering and city inspections from start to finish.
• Emergency Shoring: If a wall has already collapsed, we can deploy shoring to stabilize the slope before reconstruction begins.

If your wall is rotating, cracking, or separating from the soil, it is time to address it properly.
