Napa Concrete serves Davis homeowners with concrete floor installation, driveway replacement, patio construction, and foundation work. We know the Sacramento Valley clay that runs under most of Davis - and we build every project to handle it. Licensed, permitted, and responsive: we reply within 1 business day.

Davis homeowners adding ADUs, converting garages, or building additions on the city's clay-heavy lots need concrete floors that account for soil movement from the start. That means proper base preparation, vapor barriers to handle wet-season moisture, and slab thickness matched to the load being placed on it. We install interior concrete floors for residential projects throughout Davis, from the older neighborhoods near downtown to the newer subdivisions on the east side. Learn more about our concrete floor installation service and what the process looks like.
A large share of Davis driveways - especially in older neighborhoods like Old North Davis and the Avenues area - were poured decades ago and have been pushed around by tree roots and clay soil ever since. Cracked panels, lifted edges, and separated joints are standard in these neighborhoods. When a driveway has more than a couple of isolated cracks, replacement with a properly reinforced new slab is almost always a better value than patching.
Davis summers push past 95 to 100 degrees Fahrenheit regularly, and a solid concrete patio gives homeowners outdoor living space that holds up in that heat without the maintenance demands of wood decking. The key in Davis is proper slope and drainage - winter rain is concentrated into a short wet season, and flat patios with nowhere for water to go develop problems quickly on clay soil. We design drainage into every patio we pour.
Older streets near the UC Davis campus and downtown Davis have sidewalk panels lifted by the root systems of mature trees that have been growing for 50 to 100 years. City code places responsibility for sidewalk panels on adjacent homeowners. When panels are raised enough to create a trip hazard, replacement to current grade is the right fix - patching a raised panel rarely lasts more than a few years before the root continues its work.
Newer subdivisions in Mace Ranch, Wildhorse, and other east-side Davis neighborhoods are on slab foundations built from the 1980s onward. Many homeowners in these areas are now adding ADUs or expanding square footage and need a matching slab for the addition. We pour residential slabs to current California code requirements, with rebar sizing and vapor barriers appropriate for Davis's wet winters and hot summers.
Davis sits in the flat Sacramento Valley on expansive clay soil that behaves like a sponge. When winter rain arrives between November and March, the clay absorbs water and swells. When summer heat pushes temperatures past 95 to 100 degrees Fahrenheit - which happens regularly from June through September - the clay dries out and shrinks. That cycle repeats every year, and it is the reason driveways crack, sidewalks heave, and concrete patios develop uneven surfaces throughout the city. Concrete that was poured without adequate base preparation, reinforcement, or control joints is especially vulnerable. The clay does not care how old the slab is; it will keep moving until the subgrade is stabilized.
The age of Davis homes adds a second layer. A large share of the housing stock near downtown and the UC Davis campus was built between the 1950s and 1980s, when concrete was often poured thinner and with less reinforcement than current standards require. Some of the oldest homes in Old North Davis and the Avenues neighborhoods predate modern building codes entirely. The City of Davis Building and Safety Division issues permits and inspects concrete and foundation work throughout the city. Permitted replacement work built to current standards will outlast anything it replaces - and keeps you covered if questions arise when selling.
We pull permits through the City of Davis Building and Safety Division and know what residential concrete and foundation projects require for plan-check approval in this municipality. Davis is a flat city, which makes equipment access and concrete truck staging straightforward across most neighborhoods. The main operational variable is older downtown lots and the Avenues area, where root systems from mature oaks and elms can extend several feet under adjacent driveways and sidewalks and sometimes need to be addressed before a new slab can be placed.
Davis is a city most people navigate by bike as much as by car, and the street grid near the UC Davis campus is dense with mature trees and established landscaping. The Yolo Causeway on Interstate 80 is the landmark commuters use heading toward Sacramento - and properties east of the Causeway toward the edge of town tend to be newer subdivisions with different concrete needs than the older core. We work throughout all of Davis, from Old North Davis and the Avenues to Mace Ranch and Wildhorse.
We also serve homeowners in nearby Woodland and Vacaville and other Yolo and Solano County communities in this part of Northern California.

(707) 254-6177Davis is a mid-sized university city of about 68,000 residents in Yolo County, roughly 15 miles west of Sacramento along Interstate 80. The city is defined by UC Davis, one of the largest campuses in the University of California system, which sits at the western edge of downtown and shapes much of the city's character. Davis is widely recognized as one of the most bike-friendly cities in the country - the flat terrain and established bike lane network mean a large share of daily trips happen on two wheels. The city of Davis has about 55% renter-occupied housing, driven largely by the student population, which means owner-occupied homes represent a minority but a highly invested one - homeowners here tend to take property upkeep seriously.
Housing in Davis spans a wide range. The oldest neighborhoods - Old North Davis, Old East Davis, and the tree-lined streets of the Avenues area - contain homes from the early 1900s through the mid-20th century, many of them wood-frame bungalows with mature oak canopies overhead. Newer subdivisions on the city's east and south edges, including Mace Ranch and Wildhorse, were built from the late 1980s through the 2000s and feature larger single-family homes on slab foundations with attached garages and concrete driveways. We serve all of these neighborhoods. Homeowners in nearby Woodland and Vacaville can also reach us for the same concrete services.
