Stamped concrete is a slab with a pattern pressed into the surface while the mix is still workable, and color worked in so the finish runs deeper than a coating. Homeowners choose it for patios, walkways and pool decks where a plain gray slab would look unfinished next to the house. Patterns run from brick and slate to wood plank and cut stone. Underneath the pattern, it is ordinary flatwork: base, reinforcement, thickness, joints.
We are a concrete contractor, and most of what we pour is flatwork: driveways, a sidewalk here and there, patios, and the stamped work that shares every fundamental with them. Savannah and Pooler homeowners call us for new pours and for tearouts of slabs that are past patching. Stamping happens in one window, after the concrete has stiffened enough to hold an edge and before it has gone too far to take one. That window is short.
Most stamped concrete that fails was lost before the truck arrived. Base not compacted, so the slab bridges soft spots and cracks along them. No wire mesh or rebar, or reinforcement laid flat on the ground where it does nothing. Joints cut too late. Release powder washed off unevenly, which shows up as blotching once the sealer goes down, and there is no fixing that afterward. None of it is exotic. It is attention, in order.
The median home in Savannah was built in 1971, so plenty of the flatwork we replace has been in the ground for decades and owes nobody anything. Getting a new slab to last that long is unglamorous work: forms set true, subgrade compacted, steel held up in the middle of the pour, joints placed where the slab wants to move anyway. We would rather spend an extra hour on the base than come back to look at a crack. Call for a free estimate.

Stamped concrete starts as an ordinary slab: four inches poured over compacted base, wire mesh or rebar for crack control. Color goes in the mix or on the surface, then mats press the pattern while the slab is still plastic. Stamp late and the impressions come out shallow and faint.
Driveways carry weight, so we pour thicker than a patio, set rebar on chairs and cut control joints on a grid. Ask any concrete contractor what fails first on a stamped concrete driveway and the answer is sealer: hot tires lift it, so it gets recoated every few years.
Scale decides more than the catalog does. Most stamped concrete patterns copy stone or brick, and big ashlar slate that reads well on a wide patio looks cramped on a four foot sidewalk. Commercial concrete and any concrete sidewalk take simpler texture: easier to patch, easier to keep flat.
Stamped concrete is flatwork with a pattern pressed into the surface while the slab is still soft, so the texture belongs to the concrete itself rather than sitting on top of it as a coating. We pour it, color it, and stamp it before it sets. What you get is a patio, a walkway or a driveway carrying the look of stone, brick or plank while behaving like a slab underneath. Savannah's median home was built in 1971, so most of what we work around is a house past fifty, and the pattern gets chosen against what is already standing there.
Pattern choice comes down to scale and to what the house already carries. Large ashlar slate reads calm across a wide concrete patio and reads busy on a narrow sidewalk. Running bond brick sits comfortably next to older brickwork, and wood plank suits a covered slab. Color works in two parts: a base color through the field, and a release powder that darkens the joints and gives the stamp its depth. On a home from the early seventies, muted colors almost always settle in better than bright ones. A test panel poured on site answers the question when the call is close.
Most of the failures we get asked to look at started under the slab rather than on it. Poor compaction lets the subgrade settle, and the concrete follows it down. Cracks that wander across a field instead of following a control joint usually mean the joints were cut late or spaced too far apart. Stamping late leaves a shallow impression that wears flat within a few seasons, and sealer rolled over a slab that has not finished drying turns cloudy white. On older houses we check where the downspouts land, since water running along a patio edge undermines it quietly.
Getting stamped work right is mostly labor and timing, not material. The slab needs the same foundation as any concrete driveway: compacted subgrade, honest thickness, rebar or wire mesh set on chairs instead of dragged up out of the dirt after the truck arrives. It also needs enough hands on site the day of the pour, because the window between finishing and stamping is short and closes on its own schedule. Permitting inside the city runs through the City of Savannah, and a job out toward Pooler follows that jurisdiction's process instead. We handle the paperwork. Call for a free estimate.
We walk the area with you and measure it, check how water moves across the yard, and look at what the existing slab or dirt is doing. Old driveways in homes built around 1971 often sit on thin, unreinforced concrete. That changes the base work.
You get the scope in writing: square footage, slab thickness, reinforcement, the stamp pattern and release color, and the joint layout. Nothing starts until you have read it. We handle the paperwork side of concrete installation and schedule around inspection timing where a permit applies.
Breaking out old concrete is the loud part. We haul the debris off, then cut in a compacted graded aggregate base and run a plate compactor over it in lifts. Skipped compaction is why driveways settle at the apron and crack in a year or two.
Forms get set to line and grade with fall away from the house. Sidewalks take wire mesh or fiber; a concrete driveway takes rebar on chairs, four inches minimum, thicker at the approach. We pour a stiff mix, screed it, and bull float before bleed water rises.
Stamping happens in a narrow window: too wet and the mat sinks, too dry and the pattern is shallow. We stamp, cut control joints, wash off release, then seal once it has cured. We walk sidewalks and driveways with you and explain how to keep the color.
Two stamped patios the same size can land far apart, and the reason is usually the site rather than the pattern. Most of what moves the number is something you can walk out and look at before we ever quote it.
| What changes the price | Which way | Why |
|---|---|---|
| Old slab or asphalt sitting where the new work goes | Costs more | It gets broken out, loaded and hauled before we form anything. |
| Roots, a stump, or a buried line running under the pour | Costs more | Locating and hand digging around them is slow work that no machine does for us. |
| Truck can back within a chute length of the forms | Costs less | Concrete goes straight from the chute into the forms, so we skip the pump and the buggy runs. |
| Back yard reached only through a narrow gate | Costs more | Every yard of concrete comes through by hose or by hand, and stamping runs on a short clock. |
| Slab carrying vehicles instead of foot traffic | Costs more | A driveway wants more depth and rebar on chairs where a patio does fine on wire mesh. |
| Soft or filled subgrade under the pad | Costs more | It has to come out and be replaced with compacted stone, or the stamped surface cracks along the soft spot. |
| Ground already falling away from the house | Costs less | We set the slope into the pour rather than building up grade or running a drain line. |
| Borders, a second pattern, or a color change | Costs more | Each transition means its own forming and finishing while the concrete is still workable. |
Ask every bid to put the same things in writing: slab thickness, whether the steel is rebar or wire mesh and how it is held off the ground, base depth, joint layout, and who hauls off the old concrete. A bid missing those is not a lower price, just a vaguer one. We quote it the same way in Savannah, Pooler, Bluffton and Hilton Head Island, and a lot of driveways here date to the original build, so what comes out first often decides the rest.
Stamped concrete costs more than a plain broom-finish slab, and the gap comes from labor and materials rather than the concrete itself. Color hardener, release agent, the mats, and the crew time it takes to press and detail a pattern before the slab sets all add up. The subgrade, the rebar or wire mesh, and the pour are the same. We price each patio after we see it.
Color that goes into the concrete holds up better than color that sits on top of it. Integral color mixed through the batch and a broadcast color hardener worked into the surface both put pigment in the slab itself, so wear and sun exposure do not strip it down to gray. Surface stains fade faster. Sealer carries UV inhibitors and takes the brunt of it.
Most stamped patios want resealing every two to three years, and the slab tells you when. Watch for color looking flat or chalky, water soaking in instead of beading, and dirt that no longer rinses off. A driveway with tires turning on it and full afternoon sun burns through sealer faster than a shaded patio. Clean it, let it dry, then reseal.
Yes, if the slab underneath is sound. We pour a stamped overlay two to three inches thick over concrete that is level, well drained, and free of structural cracks, tying the new work into the old with a bonding agent. A slab that has settled, heaved, or cracked through will telegraph that damage into the overlay, so we look at it first and say so.
Running bond and herringbone brick come up most often, since much of the housing here dates to around 1971 or earlier and brick reads as native to it. Ashlar slate and seamless stone textures suit newer builds and pool decks. Cobblestone borders with a plain field inside cost less than stamping wall to wall and still frame the space. We bring sample boards.
Sealed stamped concrete gets slick when wet, the same as sealed plain concrete or tile does. The fix is a grit additive, usually a fine polymer or silica, broadcast into the sealer coat. It adds traction without changing how the surface looks. Pool decks and any patio with steps get it as a matter of course, and the deeper stamped textures shed water on their own.
