Concrete Retaining Walls
Los Angeles

Concrete retaining walls are structural masonry walls built to hold back soil, correct the natural slope of the ground, prevent erosion, create flat usable areas on sloped lots, and manage water drainage on hillside properties. In Los Angeles, concrete retaining walls are essential for hillside and canyon properties, sloped driveways, terraced gardens, and commercial properties with grade changes. DiBara Masonry has been installing and repairing concrete retaining walls across the greater Los Angeles area for over a century.

Poured concrete retaining walls are formed with concrete mixed and poured into temporary molds (forms), creating a monolithic, seamless structure with very high compressive and tensile strength when reinforced with steel rebar. They are ideal for taller walls or those bearing heavy surcharge loads. Concrete block (CMU) retaining walls use precast concrete blocks mortared together with reinforcement added in the cores. They are more economical for shorter to medium-height walls and offer flexibility in design. DiBara Masonry recommends the right type based on the wall’s height, load, soil conditions, and budget.

The maximum height of a retaining wall without engineering review and permits in Los Angeles is typically three to four feet, depending on local jurisdiction. Walls taller than this require a structural engineer’s design, building permits, and inspections. With proper engineering, poured concrete retaining walls in Los Angeles can be built to considerable heights, ten feet or more, to accommodate steep hillside conditions. DiBara Masonry handles all permitting and works with structural engineers when required for taller wall installations.

DiBara Masonry engineers concrete retaining walls for Southern California’s seismic environment by using appropriately sized and spaced steel rebar reinforcement, ensuring footings extend below the frost line and into competent, undisturbed soil, designing walls with adequate base thickness for the soil load and surcharge, and incorporating drainage systems to prevent hydrostatic pressure buildup behind the wall. All seismically sensitive walls are designed per California Building Code requirements for retaining structures.

Yes. Concrete retaining walls are highly versatile and can serve both structural and aesthetic purposes simultaneously. They can be finished with stucco, stone veneer, brick facing, or stamped concrete textures to complement the surrounding landscape. DiBara Masonry designs walls that perform structurally while also functioning as attractive landscape elements, creating clean, modern garden terraces, decorative planting beds, or elegant boundary features. Wall-integrated planters, lighting, and cap details are all available as design options.

A standard residential concrete retaining wall project in Los Angeles, from excavation to completion, typically takes one to three weeks depending on the wall’s height, length, and complexity. Poured concrete walls require time for formwork assembly, concrete pour, and curing before the forms can be removed, adding several days to the timeline. Walls requiring engineering review and permits may have longer lead times. DiBara Masonry provides a complete project schedule before beginning work.

A properly designed and constructed concrete retaining wall with adequate drainage can last 50 years or more. The most common causes of premature failure are inadequate drainage leading to hydrostatic pressure, insufficient reinforcement for the actual soil load, and seismically induced movement without proper engineering. DiBara Masonry builds walls designed for long-term performance, and their century of masonry history in Southern California means they build to stand the test of the region’s climate and geology.

Every concrete retaining wall requires a drainage system behind it to prevent the buildup of hydrostatic water pressure, which is the leading cause of retaining wall failure. Standard drainage elements include a gravel or crushed rock backfill layer immediately behind the wall, a perforated drain pipe (French drain) at the base of the wall to collect and redirect groundwater, weep holes at regular intervals in poured concrete walls, and surface grading to direct runoff away from the top of the wall. DiBara Masonry integrates all these elements as standard practice.

Yes. DiBara Masonry repairs concrete retaining walls damaged by cracks, water infiltration, settlement, seismic activity, or structural failure. Depending on the severity, repairs may include crack injection with epoxy or polyurethane foam, carbon fiber strapping to stabilize a bulging wall, partial reconstruction of failed sections, drainage improvement to address the root cause, and resurfacing to restore the wall’s appearance. They honestly assess whether repair or full replacement is the most economical long-term option.

Concrete retaining wall costs in Los Angeles depend on the wall type, height, length, site access, drainage requirements, and permitting. Poured concrete walls generally range from $40 to $80 per square foot of wall face. CMU block retaining walls are typically $30 to $60 per square foot. Taller walls requiring engineering can be more.
