concrete foundation &
slabs
in san mateo – building on solid ground
Here's what keeps builders and property owners up at night – the concrete slab foundation they're about to pour, because when you get this wrong, everything that comes after is compromised.
Foundation problems don't show up immediately.
They reveal themselves 5, 10, even 15 years later – long after your contractor has moved on. Cracks in walls. Doors that won't close. Floors that aren't level. And by then, you're looking at repair bills that dwarf what proper installation would have cost.
Here's the terrifying part: with property values what they are in San Mateo, a foundation problem doesn't just cost you repair money – it destroys your property value when it comes time to sell. Buyers see foundation issues and either walk away or demand massive price reductions.
At San Mateo Concrete Services , we're foundation contractors who specialize in concrete foundation construction for Bay Area conditions. We don't guess, we don't cut corners, and we don't use cookie-cutter approaches that ignore your specific site conditions.
why our
concrete foundations last generations
The difference between a slab foundation that lasts and one that fails comes down to what happens before we ever pour concrete .
San Mateo County has some of the trickiest soil conditions in California – expansive clay soils that swell and shrink with moisture, seismic activity that requires specific engineering, hillside properties with unique challenges.
Foundation contractors who don't understand these factors create problems that show up years later. We test soil conditions. We engineer solutions for your specific site. We account for seismic requirements. We design drainage systems that prevent water-related movement. And we use reinforcement and concrete mixes appropriate for the loads your structure will carry.
For new homes in Hillsborough, additions in Burlingame, or commercial buildings in Foster City, we provide concrete slab foundation construction that protects your investment for the long term.
what's included in our
foundation construction
Every concrete foundation we build includes comprehensive soil testing, engineered design, proper excavation, drainage systems, quality reinforcement, and concrete mixes formulated for Bay Area conditions. Because when you thirst for a foundation that protects your investment, you need residential concrete contractors near me who understand that what happens underground determines everything above ground.

frequently asked questions
about concrete foundation & slabs
How much do concrete slabs cost?
Concrete slabs price varies dramatically based on size, type, soil conditions, and engineering requirements. Simple residential slabs might start around $10,000-$15,000. Larger homes or complex slab foundation designs can run $30,000-$50,000 or more. The cost of concrete per yard is just one small factor – engineering, site prep, reinforcement, and proper installation matter far more. Call (650) 629-7258 for accurate pricing based on your project.
What's the difference between slab and other foundation types?
A concrete slab foundation is poured directly on prepared ground as one continuous piece. Stem wall foundations have a perimeter wall with a slab inside. Pier and beam foundations use posts to support the structure above ground. Slab foundations work well for level lots with stable soil. Other types make more sense for slopes or challenging soil conditions. We'll recommend what works best for your property.
How long does foundation construction take?
Most residential concrete foundation work takes 1-2 weeks from excavation to final cure. Larger projects or challenging sites take longer. Commercial concrete foundations depend on size and complexity. Weather affects scheduling since concrete needs proper conditions to cure. We'll give you a detailed timeline during your consultation.
Do you work with architects and engineers?
Yes, we regularly collaborate with architects, structural engineers, and builders throughout the Peninsula. We can work from your engineer's plans or help connect you with qualified professionals if you need design services. Our experience means we can provide valuable input during planning to optimize your concrete foundation design.
What soil testing do you perform?
We conduct soil analysis to understand bearing capacity, composition, and moisture characteristics. This tells us what type of slab foundation design works best, how deep we need to excavate, what base materials to use, and whether special engineering is required. Foundation contractors who skip soil testing are essentially guessing – and when they guess wrong, you pay for decades.
Can you build foundations on hillside properties?
Absolutely. Many properties in Hillsborough and throughout San Mateo County have slopes that require specialized foundation approaches. We've built on some of the most challenging terrain on the Peninsula. Hillside concrete foundation work requires different engineering than level lots, which is why experience with local conditions matters.
What makes Bay Area foundations different?
San Mateo County has expansive clay soils that swell with moisture and shrink when dry. We also have seismic requirements that other regions don't. Residential concrete contractors near me who don't understand these factors use approaches that work elsewhere but fail here. We engineer every concrete slab foundation specifically for Bay Area soil and seismic conditions.
Do you handle foundation inspections and permits?
Yes, concrete foundation work requires multiple inspections at different stages. We coordinate all required inspections and handle permit applications as part of our service. We have established relationships with building departments throughout the Peninsula, so we know exactly what's required and how to get approvals efficiently.
What's included in your foundation service?
Everything needed for a complete installation: soil testing and analysis, engineered design, site excavation, base preparation, drainage systems, vapor barriers, reinforcement placement, quality concrete , proper curing, and final inspection coordination. Unlike some foundation contractors who itemize everything separately, our estimates include all necessary work for a code-compliant installation.
How do you prevent foundation problems?
Proper soil analysis, adequate base preparation, engineered drainage, appropriate reinforcement, correct concrete mix design, and proper curing procedures. Most foundation problems are preventable with proper installation. That's why choosing experienced foundation contractors who understand local conditions matters more than saving money upfront. The concrete slabs price you pay today determines whether you have problems for decades.
Can you do foundation work for additions?
Yes, we regularly build concrete foundations for room additions, ADUs, and other expansion projects. Matching new foundation work to existing structures requires careful planning and engineering. We ensure proper connections and account for how new and old foundations will interact over time.
