Foundation Repair & Underpinning

A failing foundation is more than just cracks in your wall; it threatens the entire safety and value of your home. In Los Angeles, shifting soils, earthquakes, and poor drainage often cause foundations to settle, sink, or crack. Alpha Structural, Inc. offers comprehensive foundation repair services using advanced underpinning methods to stabilize and lift your foundation back to its original position.Our process begins with a thorough inspection by a licensed structural engineer. We then design...

Hillside & Landslide Repair

Building on a hillside in Los Angeles offers stunning views but also unique structural risks. Heavy rains, erosion, and seismic activity can lead to landslides, retaining wall failure, and foundation movement. Alpha Structural, Inc. specializes in hillside stabilization and landslide repair, protecting your property from gradual slope failure and sudden ground shifts.Our engineers assess soil composition, drainage patterns, and existing retaining structures to design a custom repair system. Solu...

Earthquake Retrofitting & Soft Story Reinforcement

Living in Los Angeles means accepting the reality of earthquakes. Many older buildings, especially those with soft story configurations (open first floors for parking or retail), are dangerously vulnerable to collapse during a major quake. Alpha Structural, Inc. is a leading provider of earthquake retrofitting and soft story reinforcement, bringing older buildings up to current seismic codes without altering their character.Our retrofitting solutions include cripple wall bracing, foundation bolt...

Foundation repair in Los Angeles

When a foundation settles, sinks, or cracks, the damage usually spreads into walls, floors, and doors before most people realize the cause. Our work starts with an inspection by a licensed structural engineer who looks at the soil, the framing, and how the foundation has moved. From there we design a repair that may use pressed piling, helical piers, or concrete underpinning, then we build it ourselves. We handle slab, raised, and hillside foundations, from small settlement cracks to full replac...

Hillside repair in Los Angeles

Hillside properties face slope movement, erosion, and wet-season saturation that can slowly undermine a home. We assess the soil, drainage, and any existing retaining structures before recommending a fix, which might include helical tiebacks, soldier pile walls, soil nailing, or grade beams. Our aim is to stop active movement first and then keep it from returning. We work alongside local geotechnical specialists when a site calls for it. Signs like cracking walls, tilting trees, or doors that no...

Earthquake retrofitting in Los Angeles

Older buildings in Los Angeles often lack the bracing and connections that modern seismic codes require. We retrofit these structures by adding cripple wall bracing, foundation bolting, steel moment frames, or shear walls, all designed to keep the original character of the building intact. Because we engineer and build the upgrade ourselves, the plan is tailored to your structure and meets current requirements. We serve single-family homes, apartment buildings, commercial properties, and unreinf...

Soft story retrofit in Los Angeles

A soft story building has an open first floor, often used for parking or retail, sitting beneath several stories of living space. That open level is the weak point in a strong shaking event. We reinforce it by adding steel columns and diagonal bracing that create a rigid support system. Our design meets the requirements of the Los Angeles Soft Story Ordinance and the owner's building code obligations. Because we handle the engineering and construction together, the work stays coordinated from pe...

Retaining wall contractor in Los Angeles

Retaining walls hold back soil on slopes and grade changes, and in Los Angeles they must handle heavy rain, saturated ground, and seismic loads. We design and build walls around your specific soil conditions and drainage patterns, with the engineering done by our licensed team. Options include soldier pile walls, tieback systems, and grade beam construction, depending on the site. We also repair failing walls that show bulging, cracking, or tilting. Our work takes into account how water moves th...

Basement expansion in Los Angeles

Adding a basement is a structural project that requires careful planning around the existing foundation, soil, and groundwater. We start with an engineering assessment to confirm the home can support excavation and to design the shoring and new structure. Our team builds the new space with the same attention to code compliance and waterproofing that we bring to our foundation work. Because we are licensed to engineer and build, the plan and the construction stay with one team. Basement projects...

Concrete slab replacement in Los Angeles

A sinking or cracked concrete slab can cause uneven floors, drainage problems, and trip hazards. Replacing a slab properly means first finding out why it failed, whether from soil movement, poor compaction, or water. We engineer the replacement so the new slab sits on a sound base and meets current codes. Our crew then removes the damaged section and pours the new slab to the required specifications. For slabs that have only settled, we can often stabilize them rather than replace them entirely....

Spalling concrete repair in Los Angeles

Spalling happens when the surface of concrete flakes or breaks away, often because moisture gets in and the reinforcing steel corrodes and expands. Left alone, it weakens the structure and can expose the steel further. We assess the extent of the damage to determine whether a patch will hold or whether the affected section needs to be rebuilt. Repairs involve removing the loose concrete, treating the exposed steel, and restoring the surface with appropriate materials. Because we are structural e...
