We install concrete floors in Alpharetta homes and businesses: garage slabs, basement floors, workshops, storage buildings, and the plain interior surfaces that carry cars, shelving and foot traffic every day. A concrete floor is only as good as what sits under it. The median house here was built in 1996, which means a lot of the slabs we look at are old enough to show settling, cracking, or moisture working up through the surface. Some of those can be resurfaced. Some need to come out. We tell you which one yours is after we have walked the property and looked at the slab itself, not before.
Every job starts with the ground. The county is hilly, with about 241 feet of relief within a few miles, and the grade changes from one lot to the next, so we grade and test each site before a single form goes in. Rion soil, which drains well, is the most common type around here, but it varies, and we test for what is actually under your floor. Then comes the base: compacted stone, a vapor barrier where the floor is inside, and reinforcement sized to the load it will carry. We handle the permit. The pour, the finish and the cure follow in that order, with nothing skipped to save a day.
Most floor failures trace back to water or to a base that was rushed. The area gets about 50 inches of rain a year, and a slab poured over loose fill, or with no way for water to move off the site, will let you know within a few seasons: hairline cracks that keep widening, a garage floor tipping toward one wall, a basement that always smells damp. Getting it right takes more time up front, mostly in excavation and base work you will never see once the concrete is down. That is the part of the job we do not shorten. Call for a free estimate.
What moves the number on a slab is mostly the work that happens before the pour. Grading a sloped lot, hauling out an old slab, the thickness the load calls for, and whether the section carries rebar or wire mesh all show up on the estimate. Fulton County has 241 feet of local relief within a few miles, so two slabs of the same size can land far apart. An honest figure starts with seeing the site, so call for a free estimate.
A driveway fails from underneath, not on the surface. We dig down to firm subgrade, compact a crushed stone base in lifts, and set rebar on chairs so the steel sits inside the slab instead of on the dirt. With about 50 inches of rain a year, water has to leave fast, so every driveway gets pitched away from the garage. Control joints go in early, before the concrete picks its own crack lines. Broom finish is standard; stamped and decorative finishes are available.
Garage floors, basements, workshops and additions all get the same groundwork: a compacted base, a vapor barrier under the slab, and reinforcement sized to what the floor will carry. Skip the barrier and moisture comes up through the finish later, lifting paint and clouding sealer. The median home in Alpharetta was built in 1996, so many of the floors we replace are pitted or dusting at the surface. Finishes run from a hard steel trowel to polished, stained or sealed concrete.
Not every cracked slab needs to come out. The first job is finding the cause: fill that was never compacted, roots pushing up, or water washing out the base. Hairline shrinkage cracks can be routed and sealed. A section that has dropped usually needs to be cut out and replaced, with dowels drilled into the old concrete so the new pour stays level with it. Rion soil drains well, but Fulton County soil varies, so we test before deciding anything.
A concrete floor is only as good as what sits under it, so that is where we start. Before any slab goes in, we test the ground on your property and grade the site for what we find. Fulton County is mostly Rion soil, which drains well, but it changes from one part of the county to the next. The land moves too: there are 241 feet of local relief within a few miles. We never assume one lot behaves like the one beside it. We check.
The median home here was built in 1996, so many garage and basement floors are now old enough to show their age. Some can take a new surface over the top. Others need to come out, and we look at the existing slab before saying which. From there the installation runs in a fixed order: base, reinforcement sized to the load, pour, then control joints placed where the concrete wants to move. Finishing gets the time it needs, whether the floor stays plain, gets polished or goes decorative.
Cracks, low spots and standing water usually trace back to a rushed base or a skipped step. With about 50 inches of rain a year, water matters as much as strength, so we slope surfaces away from the house and give runoff somewhere to go. When a project needs a permit, we handle the permit. None of this is complicated. It just has to be done in order, every time, and we don't cut a step to finish a day early. Call for a free estimate.
The right system depends on what the floor has to carry and how it has to look. A garage or shop floor needs thickness and reinforcement sized for vehicles, tool chests and point loads. A basement or finished living space can often take a thinner topping, polished or stained, over a sound existing slab. Decorative work, including stamped and dyed surfaces, suits patios and entry floors where appearance matters as much as strength. Commercial floors add foot traffic, rolling carts and cleaning chemicals to the list. We start with how the space gets used, then choose the mix, the reinforcement and the finish to match.
In Alpharetta the median home was built in 1996, so a flooring project often begins on a slab that has already carried a household for decades. Before we recommend anything, we check that slab for cracks, moisture and level. Fulton County is hilly, and while Rion soil drains well and dominates the county, it varies from lot to lot. Every site gets graded and tested on its own. Where the existing slab is sound, an overlay or a polished finish makes sense. Where it has settled or holds moisture, we say so plainly, and the better answer may be removal and a new pour.
Most concrete floor failures trace back to the choice of system, not the trowel work. An epoxy coating laid over a damp slab will lift and blister. A thin overlay poured across a moving crack will show that crack again. A slab sized for foot traffic will not hold up under a loaded truck. With about 50 inches of rain a year here, we treat moisture testing as part of the installation, not an extra. Getting it right means grinding, patching and cutting control joints where they belong. Sometimes it means letting a slab sit before anything goes on it. Call for a free estimate.
Yes, as long as the slab underneath is sound. In kitchens and living areas the stain soaks into the surface rather than sitting on top of it, so there is no coating to peel, and a good sealer handles spills. Garages ask more. With about 50 inches of rain a year, wet tires roll in often, and hot tires are hard on any finish. We use a tougher sealer there.
It depends on the job, and a number that fits every building fits none of them. Square footage is only the start. Slab thickness, the reinforcement the load calls for, what the existing surface needs before we pour or finish, and the finish itself all move the figure. A polished lobby and a broom-finished back room are different projects. Call for a free estimate, which starts with measuring the space and looking at the slab.
Warehouse floors are figured the same way, with more variables in play. Forklift traffic and racking loads decide slab thickness and reinforcement. Joint layout matters more across a big open floor. So does flatness, if you run tall racking. Then there is the finish: hardened, sealed, or polished. Each of those changes the number. Until we know the building and what the floor has to carry, any figure we gave you would be a guess.
For commercial properties we install new structural slabs, polished concrete, stained and sealed floors, and hardened finishes for shops and warehouses. We also resurface existing slabs where the base is solid and only the top has worn. Professional services and health care are the area's two largest industries, and both tend to want the same thing: a floor that looks clean, is easy to maintain, and stands up to steady foot traffic.
Yes. Reinforcement is sized to the project, not pulled from a default. A garage slab, a patio and a loading area carry very different loads. The mesh gauge, the spacing, and whether rebar makes more sense all follow from what the slab has to hold and the conditions underneath it. We test every site before work starts, and the reinforcement plan comes out of that testing, along with the slab thickness and the base.
Our work covers towns across metro Atlanta, and the full list is in the service area section of this page. Each one is served on the same terms: the same site testing, the same materials, the same finish standards and the same free estimate. A homeowner in Roswell gets exactly what a homeowner in Alpharetta gets. If you are not sure whether your street falls inside that area, call and ask.
