Serving Dublin, CA and surrounding areas. (925) 536-0012
Dublin Masonry & Concrete serves Union City, CA homeowners with walkway construction, driveway repair, retaining walls, and masonry work on the city's 1960s-1990s homes - built on clay soil that cracks concrete every wet season. We have served the East Bay since 2018 and reply to every inquiry within one business day.
Union City homes built in the 1960s and 1970s typically have original concrete front walks and side-yard paths that have heaved or cracked from decades of clay soil movement. Our walkway construction work uses a compacted gravel base sized for local clay conditions so the finished surface handles seasonal ground movement without the panel cracking that repeats on poured concrete in this area.
Most Union City homes have a single-car or two-car driveway that was poured in concrete when the house was built - now 35 to 65 years ago. Paver replacements handle the clay soil movement better than new poured concrete because individual units can be re-leveled if the ground shifts beneath them, rather than requiring full removal and replacement when a panel cracks or heaves.
Properties on the eastern hillside streets of Union City often have terraced yards with aging block or concrete retaining walls that were built when the homes were developed. Walls from the 1970s and 1980s on clay soil frequently show displaced blocks, bowing faces, and open mortar joints where water has entered and expanded through winter freeze-thaw cycles on cold nights.
Homes built in Union City before the mid-1970s predate several significant updates to California's seismic and soil-bearing codes. Combined with the expansive clay soil that runs throughout much of the East Bay, older foundations here are prone to cracking, corner displacement, and slab settlement that homeowners notice first as sticking doors, diagonal wall cracks, or uneven floors.
Block walls along property lines and at the back of driveways are common features in Union City's older residential neighborhoods, and many were built without the footing depth that clay soil conditions require for long-term stability. A wall built on a shallow footing in this soil will show cracking and displacement within a few wet-dry cycles - footing depth is the detail that separates walls that last from walls that need rebuilding.
Brick chimneys and decorative brick features on Union City homes built in the 1960s and 1970s are now old enough that original mortar has carbonated and softened, allowing water infiltration at the joints. Wet winters accelerate this process, and by the time a homeowner notices a brick that has moved or a chimney crown that is crumbling, the repair scope is usually larger than it would have been with earlier attention.
Union City was incorporated in 1959 and grew quickly through the 1960s, 70s, and 80s. That means the majority of the city's housing stock is now between 35 and 65 years old. At that age, original concrete driveways, front walkways, and backyard patios are well past the point where maintenance becomes unavoidable. Stucco exteriors that were standard on California tract homes of that era show hairline cracks, especially near windows, at foundation lines, and at exterior corners. Brick chimneys and garden planters built at the same time have mortar joints that have been weathering through decades of wet winters without attention. The work these homes need is not unusual - it is predictable given their age - and a contractor who works regularly in this city has seen the same issues on dozens of properties.
The soil conditions add a consistent layer of difficulty to concrete and masonry work throughout Union City. The clay-heavy soils in much of the East Bay, including under most of Union City, shrink during the dry summer and swell when winter rain saturates them. That seasonal cycle puts lateral and upward pressure on anything sitting on or in the ground - driveways, walkways, patio slabs, retaining walls, and foundation perimeters. According to the California Geological Survey, expansive clay soils are one of the leading causes of structural damage to buildings in California - and the East Bay is one of the most affected regions in the state. Any masonry or concrete project in Union City benefits from a contractor who accounts for this soil behavior at the design and base-preparation stage, not after the first season of movement.
Our crew works throughout Union City regularly, and we understand the local conditions that affect masonry and concrete work here. For projects that require city approval, we work with the Union City Building Division and handle the permit application process on the homeowner's behalf so work begins on schedule without delays from paperwork.
Union City runs along Mission Boulevard as its central corridor, from the northern edge near Hayward down through the city's core toward Fremont. The neighborhoods closest to the Union City BART station have seen new townhome and multi-family development in recent years, sitting alongside the older ranch-style homes a few blocks away. The eastern hillside streets have larger lots on steeper terrain where retaining walls and terraced yards are standard features. Near Union Landing along Whipple Road, older commercial and residential properties exist side by side, and many of the residential streets just off the main corridors have homes that have not had their flatwork or masonry touched since original construction.
We serve homeowners throughout Union City and work regularly in neighboring Fremont to the south and in Hayward to the north. The three cities share a continuous stretch of the East Bay with nearly identical soil conditions and overlapping housing age ranges, so the masonry needs we encounter in Union City are familiar ones.
Reach us by phone or through the online form. We reply within one business day and gather a few details about your project so we can come prepared to the site visit rather than asking basic questions when we arrive.
We visit your Union City property, look at the work needed, and provide a written estimate that covers materials, labor, and permit fees if applicable - so you know the complete cost before committing. No obligation and no pressure to decide on the spot.
Once you approve the estimate, we confirm a start date. For jobs requiring a city permit, we file and track the application so the approval timeline is accounted for in your schedule. Most Union City homeowners are commuters - we structure our work schedule so you do not need to be home for every day of the project.
We finish the work on the agreed schedule, clear materials and debris from the site, and walk you through what was done and what to expect during the curing period for concrete or mortar work. Any required city inspections are handled before we consider the job complete.

(925) 536-0012Union City is a mid-sized East Bay city with about 75,000 residents, incorporated in 1959 from the unincorporated communities that had developed along Mission Boulevard in Alameda County. The city sits between Hayward to the north and Fremont to the south, with Interstate 880 running along the western edge and the eastern hills rising toward the Alameda-Contra Costa county line. Most of the city's residential areas are single-family neighborhoods built on modest suburban lots, with front yards, driveways, and backyard space typical of the postwar California tract-home pattern. Union City is one of the more ethnically diverse cities in the Bay Area, with large South Asian and Filipino communities that have deep roots here and a high rate of owner-occupied housing that reflects the community's investment in maintaining and improving their homes.
The Union City BART station, near the intersection of Decoto Road and Union City Boulevard, is a central reference point for the city and connects residents to jobs across the Bay Area without a car. Near the station, newer townhome and mixed-use development has been built in recent years alongside the older neighborhoods just blocks away. Mission Boulevard runs north-south through the city as the commercial main street, lined with the shops, restaurants, and services that residents use daily. We work throughout Union City - from the neighborhoods near the BART station to the older streets behind Mission Boulevard - and serve clients in nearby Fremont and Hayward as well.
