San Lorenzo Concrete Contractor
Driveways, sidewalks, patios, and foundation work for San Lorenzo's classic ranch homes — licensed, insured, and free on-site estimates.
Concrete for San Lorenzo's classic ranch-home streets. Alameda Elite Concrete is a licensed and insured concrete contractor serving San Lorenzo, from the planned streets of San Lorenzo Village to every block in between. Whether you need a new concrete driveway to replace the original, a repaired sidewalk, a backyard patio, or foundation touch-ups, we build it to last on this flat bay-plain ground.
San Lorenzo is a tight-knit, mostly post-war community sitting between San Leandro and Hayward, and its uniform streets of 1940s and 1950s homes have concrete that is now well past its original life. That's our bread and butter here. You get honest advice, a flat-rate proposal before we start, and clean, on-schedule work. Call (510) 555-0100 for a free on-site estimate.
Pouring on San Lorenzo's Bay-Plain Soil
San Lorenzo is a flat bay-plain community near the shoreline, and that flatness is deceptive. The soil here is alluvial and bay-plain ground that trends toward softer, filled material as you move west toward the Bay. On that kind of ground the risk isn't slope or hillside clay, it's settlement and liquefaction potential, where soft or saturated soil loses strength during an earthquake.
We build for that with liquefaction-aware flatwork. Every pour starts with a properly compacted, engineered sub-base so the slab has something firm to bear on, then we reinforce with rebar and fiber mesh and place a 4,000 PSI mix so the concrete spans soft spots instead of dishing into them. San Lorenzo sits within the broader Hayward Fault and East Bay seismic region, so we reinforce with a quake in mind as a matter of course. Well-placed control joints then direct where the concrete moves, keeping cracks off the surface you see.
The climate here is mild marine bay-plain, cool and damp off the water with negligible freeze-thaw, so the concrete never faces the ice damage that plagues colder regions. What it does face is moisture, which is why we finish flatwork properly and can seal it to shrug off the damp. Call (510) 555-0100 to talk through your project.
San Lorenzo Permits and a Post-War Village Housing Stock
This is where a lot of San Lorenzo homeowners get tripped up: San Lorenzo is unincorporated, so it has no city hall and no city building department. Permits do not run through a San Lorenzo city office because there isn't one. Instead, they go through the Alameda County Public Works Agency and Community Development Agency at the County Permit Center (permit.acgov.org), the same process used in Castro Valley, with grading under Alameda County Municipal Code Chapter 15.36. County rules call for paved driveways with a minimum half-percent grade for drainage. We manage that county permit for you.
San Lorenzo's housing tells one of the most distinctive stories in the East Bay. Beginning in 1944, the Bohannon and Greenwood companies built a planned community of more than 5,000 modest single-family homes for war-industry workers and returning veterans, centered on San Lorenzo Village. The result is block after block of 1940s and 1950s ranch homes on uniform streets, an unusually consistent housing stock. Eight decades on, the original driveways, sidewalks, and patios that came with those homes are cracked, heaved, and worn, which is why San Lorenzo generates such steady demand for driveway replacement, sidewalk repair, new patios, and foundation touch-ups.
Because so many of these homes share the same era and layout, we know exactly what we're walking up to on most San Lorenzo lots, and we build the replacement to modern standards. Call (510) 555-0100 and we'll handle the county permit for you.

Questions, Answered
Do I need a permit for a driveway in San Lorenzo, and who issues it?
Yes, and because San Lorenzo is unincorporated, the permit comes from the Alameda County Public Works Agency at the County Permit Center (permit.acgov.org), not a city hall, since San Lorenzo has no city building department. It's the same county process used in Castro Valley, with grading under Alameda County Municipal Code Chapter 15.36 and county rules requiring paved driveways at a minimum half-percent grade. We manage that permit for you.
How much does a driveway cost in San Lorenzo?
A standard 2-car concrete driveway typically runs $9,000 to $18,000 installed. Many San Lorenzo homes are replacing an original 1950s driveway, so demolition and haul-away of the old slab factor in, along with reinforcement for the soft bay-plain soil. Bay Area labor and permit costs run above national averages. Your exact flat-rate price comes from a free on-site estimate.
How soon can you start a concrete project in San Lorenzo?
We can usually schedule a free on-site estimate within a few days. Start dates depend on the Alameda County permit timeline for your address and on dry weather for proper base prep and curing. Call (510) 555-0100 and we'll give you a realistic schedule.
Do you replace the original sidewalks and driveways on San Lorenzo Village homes?
Yes, that's a large part of what we do here. The original concrete on San Lorenzo's 1940s and 1950s Village homes is now decades past its service life and often cracked or heaved. We remove the old flatwork and pour reinforced, properly drained replacements built to modern standards on a compacted sub-base.
