Alameda Masonry & Concrete is the masonry contractor serving San Lorenzo, CA - replacing cracked driveways, building new walkways, and repairing foundations on the community's postwar tract homes, with crews working throughout the area since 2018.
Many San Lorenzo homes still have their original Bohannon-era concrete walkways from the late 1940s - and after 70-plus years of East Bay clay soil movement, most of them are cracked, sunken, or tripping hazards. Our walkway construction work includes proper base preparation for this area's expansive soils so the new path stays level for years.
San Lorenzo driveways built in the postwar era have been through decades of clay soil expansion and contraction, and the original concrete often has cracks, sunken sections, or surface spalling that a patch cannot fix long-term. Paver installations on these properties include a compacted gravel base that absorbs soil movement better than a monolithic concrete slab.
Most San Lorenzo homes sit on concrete slab foundations poured in the late 1940s on East Bay clay. As those soils shrink in dry summers and swell in wet winters, slab cracks and uneven floors appear over time. Foundation repair on these properties addresses both the surface crack and the drainage or soil conditions driving it.
Older block and brick retaining walls on San Lorenzo properties have often been pushed or tilted by decades of soil movement. Replacing a failing wall with one properly sized for the load and drained for the wet winters here prevents the same failure from repeating on the new structure.
Concrete masonry unit walls are a practical choice for San Lorenzo properties where privacy fencing, property line definition, or side-yard separation is needed. They hold up well against the clay soil movement common in this part of the East Bay when footings are set properly and mortar joints are maintained.
While San Lorenzo is not a pre-war city, many of its postwar homes have original brick chimneys, garden walls, and planters that have been through decades of seasonal soil movement and occasional seismic activity. We repair cracked mortar joints and spalled brick before water infiltration extends the damage.
San Lorenzo was built fast and built to a single formula - developer David Bohannon put up thousands of tract homes in the late 1940s in a tight window, using the same materials and the same slab foundation design throughout. That uniformity means the problems that show up in one part of the neighborhood show up everywhere: cracked driveways, sunken walkways, slab movement, and aging concrete that has been flexing with the East Bay clay soils for 70-plus years. There is no mystery about why the concrete is failing - the question is whether the contractor replacing it understands why it failed so the fix actually holds.
Expansive clay soils are the main driver of concrete damage in San Lorenzo. Clay absorbs water and swells in winter, then dries and shrinks in summer - and that cycle puts the same stress on slabs, walkways, and driveways every single year. A masonry contractor who does not account for this when preparing the ground before pouring new concrete is setting you up to repeat the same crack in five years instead of fifty. San Lorenzo also has flood-zone properties near San Lorenzo Creek where drainage patterns matter not just for longevity but for regulatory compliance. Getting the base right, the drainage right, and the scope permitted properly is what separates a durable repair from a patch job.
Our crew works throughout San Lorenzo regularly, and we understand the local conditions that affect masonry and concrete work here. Permits for structural work go through the Alameda County Planning and Building Department - not a city office, since San Lorenzo is unincorporated. We know what that review process looks like and handle permits on behalf of homeowners as standard practice for structural jobs.
San Lorenzo sits along Industrial Parkway and Grant Avenue with Interstate 880 running along the western edge. The community is bordered by San Leandro to the north and Hayward to the south, and the housing stock looks similar throughout - single-story postwar homes on modest lots with concrete driveways and small backyard patios. Properties near San Lorenzo Creek, which cuts through the community before reaching the bay, tend to see heavier soil saturation in wet years and may have drainage issues that come up during any concrete or grading work.
We also serve neighboring Castro Valley and San Leandro - if you have family or neighbors in either community who need masonry or concrete work, we cover both areas.
Tell us what you are dealing with - a cracked driveway, a sinking walkway, a damaged patio - and we will schedule a visit to your San Lorenzo property. You do not need to know the cause; that is part of what we look at on-site.
We assess the concrete or masonry condition, check the ground underneath for drainage or base issues, and give you a written estimate before anything starts. We will tell you upfront whether Alameda County permits are required and factor the permit timeline into the schedule - typically two to four weeks for structural work.
We remove the old concrete or masonry, regrade and compact the base layer for San Lorenzo's clay soils, and install the new surface. Rushing the base prep is the most common reason concrete fails within a few years on these properties - we do not skip it.
After the work is complete, we walk the site with you and explain the curing window - 24 to 48 hours for foot traffic, up to a week before vehicles can use a new driveway. If a county permit was required, we coordinate the inspection and hand you the permit record for your files.

(341) 895-9185San Lorenzo is an unincorporated community in Alameda County with a population of roughly 26,000 to 28,000 people packed into about 3.5 square miles. It is best known as San Lorenzo Village - the planned postwar community that developer David Bohannon built starting in 1944, producing thousands of small single-family homes in a compressed period after World War II. Those homes define the neighborhood today. They are one-story, modest in footprint, and built on concrete slab foundations with concrete driveways and small backyards - a repeating pattern that gives the community its uniform character. Most of the housing stock is now over 70 years old, and the Bohannon-era concrete that came with those homes is showing it.
San Lorenzo Creek runs through the community from the hills to the east before emptying into San Francisco Bay. The Alameda County Flood Control District manages the creek channel, and properties near it have historically faced flooding during heavy rain years. The community sits between San Leandro to the north and Hayward to the south, with Castro Valley in the hills to the east. About half of San Lorenzo's housing units are owner-occupied and half are rentals, which means the masonry and concrete work we do here comes from both homeowners maintaining long-term investments and landlords catching up on deferred repairs on aging rental stock.
