Concrete Contractor in Petaluma, CA

Concrete Flatwork & ADA Paths · Petaluma, CA

Concrete flatwork poured for homes and businesses

Rich's Paving is the concrete contractor that homeowners and property managers call in Petaluma. We pour concrete flatwork, which covers walkways, sidewalks, entry landings and concrete curbs. Slabs and pads for sheds, shops and equipment are flatwork too. We have worked across Sonoma County since 1988, and we are a family paving company in its third generation. Our crew sets the forms, places the ready mix concrete and pulls the finish.

Concrete and asphalt sit side by side on most of the sites we work. We pour the walks, the curbs and the pads, then pave the driveway or the lot beside them. Both go in on the same job, so the grades line up where the two surfaces meet. That also means one estimate and one schedule for the whole surface.

What concrete work does a concrete contractor pour in Petaluma?

At a house, most of our concrete work is flatwork. That means a front walkway, a side path to the yard and an entry landing at the door. We also pour pads for a shed, a workshop or a generator. Concrete curbs go along the edge of a drive to hold back planting beds. If the job is a full driveway slab, we cover that work on its own page. For a sitting area with a pattern pressed into it, look at a stamped patio out back.

At a business the list changes. We pour sidewalks along the building, plus concrete curbs and gutters that carry runoff to the inlets. We also form the surrounds around catch basins and channel drains. Dumpster pads take the weight of a loaded bin and the truck that lifts it. ADA pathways and curb ramps run from the accessible stalls to the front door. We pour concrete flatwork for homes and businesses, and foundations, footings and structural building slabs are not our work. A wall that holds back grade is a different job, and we build those as block and stone walls.

How a concrete flatwork job runs

Old flatwork comes out first. We break up the broken walk or slab and haul the spoil off in our own dump trucks. Then we cut the subgrade to depth and bring in crushed rock. That rock goes down in lifts and gets compacted with a plate compactor until nothing moves underfoot. Forms go in next, set to a grade that carries rain off the concrete and away from the building. Where the job calls for it, steel reinforcement goes inside the forms before any concrete arrives.

Ready mix concrete arrives by truck and gets placed inside the forms. We screed it flat, float the surface and tool the edges. A broom finish goes on last, so the walk keeps grip when it is wet. Control joints go in while the slab is fresh. Concrete Network sets the spacing rule at two to three times the slab thickness in inches, measured in feet. That puts joints eight to twelve feet apart on a four inch slab, cut a quarter of the slab depth. Foot traffic is fine after about a day, and we give you the full cure timeline before we leave.

Permits, code and clay in Petaluma and Sonoma County

Most flatwork at a house does not need a building permit. California Building Code Section 105.2 exempts sidewalks and driveways not more than 30 inches above adjacent grade. Work in the public right of way needs an encroachment permit from Permit Sonoma. Its right of way covers driveways, sidewalks, curbs and gutters. Our ground works against a slab too. The USDA Clear Lake clay, mapped in Sonoma County, opens cracks as deep as 48 inches when it dries. So we build the rock base this clay needs. The 1991 to 2020 climate normals for Petaluma Airport put July rain at 0.01 inches, so summer is our pour season.

A walkway at a business is usually part of an accessible route. Chapter 11B of the California Building Code sets its shape. Clear width for sidewalks and walks is 48 inches minimum. Running slope stays no steeper than 1 in 20, and cross slope no steeper than 1 in 48. Curb ramps hold a running slope no steeper than 1 in 12 and a clear width of 48 inches. Each ramp also carries a detectable warning surface of truncated domes in yellow. We check which rule applies before we quote. We pour walks, curbs and pads in Santa Rosa, Rohnert Park, Novato, San Rafael and Sonoma.

Should you pour concrete or pave with asphalt?

Concrete wins where a surface has to stay put and stay clean. Walkways, entry landings, equipment pads, curbs and ADA routes all belong in concrete. Concrete also holds up where water stands, and it stays a light gray instead of black. Asphalt wins on long runs and wide areas, where it goes down fast and flexes with the ground. If the job is a long driveway, read how an asphalt driveway goes down. Our guide sets the two surfaces against each other for a Sonoma County driveway.

Concrete and asphalt land on the same commercial site more often than not. Sidewalks, curb ramps, dumpster pads and ADA pathways are concrete. The drive lanes and stalls are asphalt. We pour the concrete work on the same visit as the lot surface itself. That keeps the site closed once instead of twice. Once the asphalt has cured, the stalls and access aisles get painted. Send us the plan or the address and ask for a concrete flatwork estimate.

How much does concrete flatwork cost per square foot?
Concrete Network publishes $6.50 to $10.50 per square foot to have a plain concrete slab poured. That is a national range for materials and labor, and California sits above it. Thickness, removal of the old walk, reinforcement and how much grading the site needs all move the number. Our Sonoma County concrete pricing guide breaks those drivers down.
Do I need a permit for a concrete walkway or pad in Petaluma?
Usually not for a walk or pad at grade. California Building Code Section 105.2 exempts sidewalks and driveways not more than 30 inches above adjacent grade. Work that touches the public right of way is different. That needs an encroachment permit from Permit Sonoma or your city. Our guide explains which paving jobs need a permit here.
How long before I can walk or drive on new concrete?
Foot traffic is fine after about 24 hours on a broom finished slab. Concrete Network puts driving and parking at seven days after placement. By then the concrete has about 70 percent of its potential strength. Heavier vehicles like RVs and large trucks wait at least 28 days. We give you the day by day cure milestones first.
Why does concrete crack in Sonoma County?
Two things pull on a slab here, ground movement and shrinkage. The USDA Clear Lake clay mapped in Sonoma County opens large cracks as deep as 48 inches when it dries. Concrete also shrinks as it cures. A compacted rock base handles the first, and control joints steer the second into straight lines.
Do you pour foundations or building slabs?
No. We pour concrete flatwork only. That covers walkways, sidewalks, entry landings, curbs and gutters, dumpster pads, ADA pathways and equipment slabs. Foundations, footings, stem walls and structural building slabs are not our work. If your project needs those, a foundation contractor handles them and we can pour the flatwork around it.
Do you build ADA pathways and curb ramps for businesses?
Yes. ADA pathways, curb ramps and the walks that connect them are part of our commercial concrete work. We lay them out to the current California Building Code Chapter 11B standard. We check which rule applies before we quote. The stalls themselves are striping work, and the California ADA parking rules cover the counts and signs.
