Concrete Contractor in Rohnert Park - Slabs Built for Expansive Soil
Alliance Novato Concrete is a Novato concrete contractor pouring driveways, patios, walks, steps and slabs for homeowners in Rohnert Park, built on a packed base and pitched so water runs away from your house.

Why Rohnert Park homeowners redo their concrete
Most people who call us have a driveway, patio, walk or steps that's worn out or was never right to begin with. They see cracks, a corner that's sinking or water pooling against the house after it rains, and they want to know if a new pour will do the same thing.
Usually the answer sits under the old slab. On a lot of jobs the subgrade, the dirt the slab sits on, gets raked level instead of dug out and packed, so the concrete settles right along with it. When a budget gets tight, the base is the first thing people want to cut because nobody sees it on day one. I won't cut it.
Water is the other half. Before we set a form, we check where the water runs so the slab falls away from your house, and we pour early enough to beat the midday heat that leaves a weak, dusty top.

How a Rohnert Park job runs
Call or send the form
Call (628) 209-1066 or send the form, and tell us what you're seeing, like cracks, sinking or water that pools where it shouldn't.
I come out and look
I come out myself, measure, check where the water runs and ask how you'll use the slab, then give you the estimate.
We prep and pour
Once you say go, we file any permit, which the city reviews in the order received, then prep, pour, clean up and walk the job with you.
What Rohnert Park's soil means for your slab
The city's own findings say Rohnert Park sits on highly expansive soil, ground that swells when it's wet and shrinks as it dries, and that it can damage slabs and foundations. That covers the whole city, not your lot in particular, so I look at your ground myself. It's why the base gets so much of our time here, along with rebar, the steel inside the slab that holds it together if the ground moves.
Water matters as much as the dirt. The same findings name gutters, downspouts, splash blocks and concrete landings as ways to keep rain away from a foundation, so I check where your downspouts empty before we set the slope. Where a yard drops off, concrete retaining walls hold the grade, and if a wall needs an engineer, I'll say so.
Price comes down to size, how much old concrete comes out, how much base we dig and pack, the steel and the finish. Timing turns on the permit, when there is one, and on curing, the wait while concrete gains strength before you walk or drive on it. We do the same work in Cotati, Petaluma and down in Tamalpais-Homestead Valley. Ask for an estimate to get your own figure.

Rohnert Park concrete questions
Do I need a building permit for concrete work in Rohnert Park?
Plenty of concrete work does, because the city issues building permits for any structure that's built, altered, repaired, enlarged, moved or removed. The answer for your job comes from the city's Building Division. When you need one, we find out which office handles it, do the paperwork and put in writing who's pulling it.
Do I need a city permit to widen my driveway in Rohnert Park?
Yes, if the work opens up the street or the public right-of-way, the city requires an encroachment permit, and widening a driveway apron, the sloped piece where your driveway meets the street, is one of its own examples. Running a drainpipe through the sidewalk counts too. You apply online or with the city's Engineering Division.
Who needs a contractor license for concrete work in California?
Anyone who contracts for work on a job that needs a building permit, uses employees, or takes on work worth $1,000 or more in labor and materials combined needs a current license from the state contractors board. Rohnert Park also requires a Business Tax Certificate from anyone doing business in city limits, including crews that come in from out of town.
Will my new driveway crack like the old one did?
Some cracking is normal in any slab, so we cut control joints on pour day to give it a straight line to crack along. Most of the bad cracks we tear out trace back to a base that was never packed or water running under the slab, and with the soil here, those get most of our attention.
