Serving Martinez, CA and surrounding areas. (925) 316-0136
Martinez Concrete & Masonry is a licensed masonry contractor serving Antioch, CA with retaining wall construction, driveway pavers, concrete flatwork repair, and the full range of masonry services - backed by 10+ years working in Contra Costa County.
We know the clay soils, the 100-degree summers, and the range of home ages across Antioch - from 1970s ranch houses near downtown to the newer east-side subdivisions off Lone Tree Way.
Antioch has expanded into hillside areas where sloped lots need walls that can hold back heavy clay soil during wet winters and remain stable through the dry-season shrink cycle. A wall built without proper drainage behind it will fail in Antioch's conditions - it is not a question of if, but when. Our walls are built with the drainage to match the soil. Learn about our retaining wall construction service.
Antioch's clay soils are the leading cause of foundation movement and cracking in homes across the city. Homes built in the 1970s and 80s were often built on footings that do not go deep enough to stay below the active shrink-swell zone, which means the foundation moves every year with the seasons. Catching that movement early is far cheaper than waiting for it to become a structural problem.
Standard poured concrete driveways take a beating in Antioch - the clay soil moves underneath, the summer heat bakes the surface, and cracks appear within a few years of installation without a proper gravel subbase. Paver systems flex with the ground movement better than rigid concrete, and a cracked or settled section can be lifted and releveled without replacing the entire driveway.
Block walls are standard on Antioch properties, used to divide lots, create privacy along rear yards, and contain slope on hillside properties. Walls from the 1970s and 80s are now at the age where mortar is crumbling, caps are cracking, and leaning sections are becoming a safety concern. We repair existing walls and build new ones with modern drainage details that the original installations did not include.
Front and backyard walkways in Antioch crack and heave for the same reason driveways do - clay soil movement beneath the slab. A walkway installed directly on native clay with no prepared base will shift within a few years. A proper compacted gravel base and correctly sized concrete sections handle the seasonal movement and hold up far longer.
Antioch's large stock of 1970s and 80s homes means a lot of brick, block, and stone work that has seen 40 to 50 years of weather and soil movement. Repointing mortar joints, sealing cracks, and cleaning stained masonry surfaces extends the life of the original material significantly and prevents water from getting behind it and causing deeper damage.
Antioch is one of the largest cities in Contra Costa County, with a diverse housing stock that spans from 1970s and 80s ranch-style homes near the original city center to newer two-story subdivisions built in the 1990s and 2000s in the eastern part of the city. The homes from the earlier era are now 40 to 50 years old, and the original concrete flatwork, block walls, and retaining walls on those properties were installed without the drainage details and subbase depths that would help them last in Antioch's clay soil environment. The result is cracked driveways, leaning walls, and masonry surfaces that need attention all across the older neighborhoods.
Antioch's inland location makes summers genuinely hot - temperatures in the mid-90s are normal and 100-degree-plus days happen regularly in July and August. That heat dries and cracks concrete surfaces, degrades mortar joints, and puts stress on any masonry that has not been sealed or maintained. Then the rainy season arrives in November, the clay soil swells, and the cycle of stress on foundations and flatwork starts again. A contractor who understands this seasonal pattern builds with it in mind, not against it. The California Geological Survey documents expansive soil hazard zones across the region, and much of Antioch falls within areas where this soil behavior is a known factor in construction and repair work.
Our crew works throughout Antioch regularly, and we understand the local conditions that affect masonry work here. Antioch is a big city with genuinely different neighborhoods - the older streets near downtown and the waterfront district, the mid-century subdivisions in the central areas, and the newer east-side developments off Deer Valley Road and Lone Tree Way each have different soil profiles, drainage patterns, and housing types. We pull permits through the City of Antioch and are familiar with the building department's process for structural masonry, retaining walls, and foundation work in this municipality.
The Antioch BART station at the eastern terminus of the Bay Area rail line connects thousands of residents to Oakland and San Francisco daily - many homeowners here are busy commuters who bought in Antioch because it was more affordable than cities closer to the Bay, and who need a contractor they can trust to manage the job without needing to be onsite every day. Contra Loma Regional Park in the hills above the city is a gathering point for local families, and the waterfront district along the San Joaquin River gives the city a character that is distinctly its own.
We also serve neighboring Pittsburg to the west, which shares the same clay soil challenges and similar postwar housing stock. If your property sits on the Antioch-Pittsburg border or you have work to do on both sides, we handle all of it under one project.
Call us at (925) 316-0136 or submit the estimate form on this site. We respond to all Antioch requests within one business day and confirm a visit time that works for you - you do not need to take time off work to be there, though you are welcome to be present.

(925) 316-0136Antioch is one of the larger cities in the East Bay, with a population of around 115,000 people and a housing stock that reflects three distinct waves of residential development. The oldest homes, clustered near downtown and the waterfront along the San Joaquin River, date to the early and mid-20th century. A second wave of ranch-style and two-story tract homes was built from the 1970s through the early 1990s across the central neighborhoods. The most recent growth pushed into the hills in the eastern part of the city, adding newer larger-lot subdivisions in the late 1990s and 2000s. About 58 percent of housing units are owner-occupied, which means most homeowners in Antioch have a real financial stake in maintaining their properties.
The city sits at the eastern edge of the Bay Area, with the San Joaquin River along its southern boundary and the hills rising to the north and east. Contra Loma Regional Park, with its reservoir and hiking trails, is one of the most recognizable open spaces in the city. Antioch is the eastern terminus of the BART system, which connects thousands of residents daily to Oakland and San Francisco. The city's combination of affordability relative to the rest of the Bay Area, commuter access, and range of housing types has made it a destination for working families from across the region. Neighboring Benicia to the west across the Carquinez Strait offers a contrast in character - a smaller, older city with a distinct historic downtown - while Antioch itself has the energy and scale of a growing suburb.
