Is stamped concrete right for my patio, driveway or walkway?

Our stamped concrete services in Walnut Creek give you a new slab that we pour, color, press with rubber stamp mats while it's still soft enough to shape, and then seal, so your patio, driveway or walkway gets a patterned, colored surface instead of plain gray.

Most calls start with a plain slab you're tired of looking at, or an old patio that's cracked, sinking or holding puddles and has to come out anyway. The price turns mostly on the square footage, how much old concrete we break out, the color method and pattern, and how much work the ground needs before we pour, while the schedule turns on the weather, the curing time before you can walk or drive on it and whether any part touches the street. My written estimate puts your own numbers on each of those.

How we build stamped concrete, from the dirt up

The first thing I ask is how the slab gets used, because that decides the color method, and a driveway and a quiet patio may not get the same one. Integral color, color mixed through the whole depth of the concrete, is the simplest and most forgiving choice, so a chip or a saw cut later shows the same color instead of a pale scar. It won't give you the deepest or brightest tones, so if you want a bolder look, that's a conversation we have at the estimate. From there we break out any old slab, dig out and pack the ground underneath, set the forms and the rebar, the steel that holds the slab together, and pour early in the day so midday heat doesn't leave a weak, dusty top. We color and stamp while the concrete is still soft enough to take the pattern, let it cure, which is the wait while it hardens before anyone uses it, and then seal it. I also tell you up front that stamped work needs resealing now and then, so it's part of your plan from day one. If the budget gets tight, I'd rather you pick a simpler pattern than skimp on the base, because nobody sees the base on day one but everything you paid for sits on it.

Stamped jobs often come with plain concrete beside them, and our crew handles that on the same project. A walkway out to the new patio or along the side of the house falls under our concrete sidewalk building, and if the garage slab is cracked or sinking, we can replace it with a new concrete garage floor.

What a stamped concrete job runs into in Walnut Creek

If your stamped project replaces the driveway approach, the stretch that runs from your driveway out to the street, or the front sidewalk, the city requires an Encroachment Permit. We figure out at the first visit whether your job touches the street or needs a city or county sign-off, and when a permit is needed, we can handle the application and paperwork for you.

Under the color it's still flatwork, a flat poured slab like any patio or driveway, so it needs packed soil under it, a thickness suited to how it's used and reinforcement sized to the job. That matters around here because one county soil summary rates the main soil class across Contra Costa County high for shrink-swell, which is how much the ground swells when it's wet and shrinks when it dries. That's a countywide figure, not a reading for your lot, but it's why I look hard at the dirt and where the water runs on every visit. We work out of Walnut Creek and take jobs in the cities around it, and we see the same kind of ground on jobs in Concord and Danville.

What happens when you call Alliance Walnut Creek Concrete Company in Walnut Creek

  1. Call or send the form

    Call (925) 448-9528 or send the form with the slab's rough size in square feet, what it's for, like a patio, driveway or pool deck, and whether it reaches the front sidewalk. From there we set a time for me to come see it.

  2. I walk the site with you

    I look at the slope, the soil and where the water runs, ask a lot of questions about how you'll use the slab and put a written estimate together. It lays out the size, color method, pattern, base work and price, so you know what you're paying for before anything gets dug.

  3. Paperwork first, then the pour

    Once you're ready, we sort out any permit paperwork and get the site marked or scanned for buried lines. Then our crew preps the ground, pours, colors, stamps and seals the slab.

  4. We walk the finished slab together

    At the end I walk the job with you and go over how to look after it. You'll leave knowing what to watch for and when it's time to think about resealing.

Why Walnut Creek homeowners pick our crew for stamped concrete

  • I come out to see it myself

    I come out to look at every job myself, and our own crew does the prep, the pour and the finish, with me there for the parts that matter most. The person who asked about your drainage is the same one watching the base go in.

  • Since 2013, the awkward jobs

    We've been in business since 2013, and we're best known for the tricky ones, like sloped backyards and cuts through old slabs. I'd rather take extra time working out a hard spot than guess and pour, because you can't redo a pattern once it's set.

  • Grading limits checked on slopes

    On a sloped Walnut Creek yard, I check early whether the dirt work crosses into a Site Development Permit, which the city requires for grading over 50 cubic yards or fill more than 3 feet deep outside a structure. Knowing that at the estimate means the plan and the price already account for it.

  • Licensed and insured, ask for proof

    We're licensed and insured. If you'd like to see our proof of insurance before we start, just ask, because you should know who's covered when a crew is working at your house.

The part of a stamped slab you'll be glad about later is the part nobody sees on pour day, so let's start with a look at your site. Ask for an estimate or call (925) 448-9528.

Questions about stamped concrete in Walnut Creek

What is the best color method for a stamped concrete driveway?

Color hardener is usually the better pick for a driveway, because it builds a harder skin on the surface for cars and foot traffic. The trade-off is that its color lives in that top layer, so deep damage shows gray underneath, and it has to be spread evenly or the color comes out blotchy, which is why it's a step I watch closely.

How often does stamped concrete need to be resealed?

Usually every 2 to 5 years, depending on how much traffic it takes, the weather it sees and the sealer that went on last time. A busy driveway in hard conditions can need it every year, so budget for it as regular upkeep. Resealing is ordinary care rather than a repair, and the job itself is backed by our satisfaction guarantee.

How much does stamped concrete cost per square foot in Walnut Creek?

Stamped concrete in San Francisco usually costs about $15 to $30 per square foot, which gives you a rough idea of the Bay Area market. Where your job lands depends on the size, the color method and pattern, and how much old concrete and base work there is, so the written estimate from my visit gives you the Walnut Creek price for your slab.

Will new stamped concrete crack like my old patio did?

It can still crack, because concrete moves, but a crack in a planned spot is a very different thing from the random breaks and sinking you see on a tired old slab. We cut control joints, grooves that give the slab a chosen place to crack, and line them up with the pattern so they blend in, and we put most of our effort into the base and the steel underneath, which is where old slabs usually gave out.

Is stamped concrete slippery around a pool?

It can be, because the glossier sealer finishes get slick when they're wet. A non-slip additive is worth considering on a pool deck or a walkway, and I'll bring it up at the estimate if your slab sits anywhere near water.

How do I know a stamped concrete contractor is licensed in California?

In California, stamped flatwork falls under the state's C-8 concrete contractor class, which covers forming, pouring, placing and finishing flat concrete. Every active C-8 contractor also has to carry workers' compensation insurance or a valid self-insurance certificate, even with no employees, so asking for proof of that coverage before work starts is a fair question.

  • Concrete sidewalk building

    A plain concrete walk from the driveway or gate to your new stamped patio keeps the path simple and usually costs less than stamping the whole route.

  • Garage floor concrete

    If your garage slab is cracked, sinking or chipping, a new garage floor can be poured while our crew is already at your house pouring the patio.

Plan your stamped patio or driveway now

Calling before you settle on a pattern lets me match the color method to how the slab gets used while it's still an easy change to make.
