There's a particular kind of frustration that comes with knowing exactly where the water shows up and having no idea how it got there. Maybe a thin trickle appears at the same spot on the wall after every storm, maybe a wet ring keeps returning on the floor no matter how many times you mop it up, or maybe the drywall in your finished basement has started to bubble along one seam. A&A Waterproofing has been doing foundation leak repair for homeowners around Marietta, GA, and the surrounding towns since 1996, and the fix starts with figuring out where the water is entering rather than guessing at it.
Founded in 1996 and still run by owner Allen Aschwege, A&A Waterproofing is a veteran-owned contractor specializing in below-grade waterproofing and structural repair, working out of Marietta, Georgia. Sealing active water entry points is a core part of what we do, covering crack injection, repairs at form tie holes and pipe penetrations, treatment of the cold joint where the wall meets the footing, and mortar joint repair in block foundations. Existing homes and commercial buildings make up our entire workload, since we don't bid new construction. Our crews cover Marietta along with the towns spread around it, and nobody pays for an estimate.
Leaks announce themselves in ways that are easy to spot and hard to ignore. Water running down a wall during heavy rain, a puddle that reappears in the same corner, efflorescence marking a trail from a crack, damp insulation, warped baseboards, or a rusty stain running down from a bolt hole. Left alone, that water damages finishes, feeds mold growth, and slowly works on the concrete around the opening it's using.
The opening itself is rarely the whole story. Poured walls crack as concrete cures and as soil pressure builds against them, form tie holes were never sealed properly on some homes, and the cold joint at the base of the wall is a natural seam where two pours meet. Block foundations leak through mortar joints as they age. What turns any of those into an active leak is water collecting in the soil outside, which around here means clay that holds rainfall, downspouts discharging too close to the wall, and a yard grade that sends runoff back toward the house.
Our process opens with locating every entry point rather than the obvious one. Once we know what we're dealing with, the repair gets matched to it: polyurethane injection for cracks that are actively passing water, epoxy where the crack needs structural strength restored, hydraulic cement and sealants at tie holes and penetrations, and joint treatment along the base of the wall. Allen also looks at the exterior conditions feeding the leak, because sealing the hole without addressing the water pressure behind it tends to move the problem a few feet down the wall.
The result is a wall that stays dry through the storms that used to cause trouble. Drywall, flooring, and stored items stop taking damage, mold loses the moisture it was living on, and the crack or joint gets filled through the full thickness of the concrete rather than skimmed over on the surface. Qualifying repairs come with warranty coverage, so the fix is documented and stands behind itself.
Sealing a foundation leak correctly delivers more than a dry floor, and here is what homeowners get out of it.
Injection materials fill a crack through the entire depth of the wall instead of coating the visible side, which is why surface patches fail and injections hold. Polyurethane expands as it cures to seal against water already moving through the opening. Once that void is filled, the path the water was using no longer exists.
Water that keeps entering a basement moves into framing, insulation, flooring, and anything stored nearby, and the repair bill grows every season the leak continues. Closing the source early keeps a straightforward repair from turning into demolition and rebuilding. Mold remediation gets considerably more expensive once growth reaches finished materials.
Finding out why water is collecting outside that particular section of wall matters as much as sealing the opening. Our assessment covers grading, downspout discharge, and drainage conditions, and we'll tell you which corrections would take pressure off the repair. Some of those fixes cost very little and make a noticeable difference.
A single leaking crack rarely calls for a full waterproofing system, and we say so when that's the case. Matching the scope to the actual problem is how customers end up spending hundreds instead of thousands. Homeowners who want the larger solution can still have it, with the price laid out clearly alongside the smaller option.
Written records of what was found, what was repaired, and what warranty applies turn an old water stain from a red flag into a resolved issue. Real estate transactions in Cobb County go smoother when a seller can produce paperwork. Buyers ask about basement moisture nearly every time, and a clear answer helps.
Leaks often turn out to be one piece of a larger moisture picture, and these related services address the rest.
Homes with widespread water entry or a wall taking on damage generally need the problem addressed from outside, and our exterior foundation waterproofing service excavates along the wall to seal it and correct drainage at the same time. Handling it from the soil side removes the pressure driving water through the concrete.
A barrier applied to the outside of the wall keeps groundwater from reaching the concrete at all, and our foundation waterproof membrane installation work covers preparation, application, and careful sealing at every seam and transition. This is the layer that determines how long an exterior system performs.
All of our below-grade services sit under the umbrella of foundation waterproofing, from single crack repairs through complete exterior systems. Which approach makes sense depends on your wall, your soil, and how much water the property is dealing with, and we'll go through that during the estimate.
Choosing who to trust with a water problem comes down to how they handle the conversation, and ours goes like this.
Allen inspects the wall, the surrounding grade, and the drainage before recommending anything, since a leak at a tie hole calls for a different repair than a structural crack. You'll hear what we found and why we think it's happening, in plain language. Nobody gets a price on work we haven't explained first.
Plenty of contractors quote a full perimeter system for a single crack, and we'd rather tell you the truth about what your foundation needs. Customers have saved real money by getting an honest answer instead of an automatic upsell. That approach has kept this business running since 1996.
Ownership here is veteran-held and based right in Marietta, which means our crews live in the same communities they work in. Word of mouth carries a lot of weight around Cobb and Cherokee counties, and we've built the business on it.
There's no charge for us to come out, inspect the foundation, and talk through the findings. Payment plans get arranged through Acorn Finance when a repair lands at an awkward moment, and veterans, active-duty military, police officers, firefighters, and EMTs all claim 10% under Hometown Heroes.
Qualifying leak repairs are backed for a minimum of a decade, and certain methods qualify for lifetime coverage. Terms are spelled out rather than implied, and we're still here to honor them.
Volume and duration are usually the difference. A brief shower may not saturate the clay soil around your foundation enough to build pressure, while the slow, soaking rains that park over Cobb County for a day will. Storms with heavy runoff can also overwhelm gutters and send a concentrated stream right beside the wall.
In most cases, yes. Injection fills the crack through the full thickness of the wall from the interior side, which means no excavation and considerably lower cost. Walls that are bowing, badly deteriorated, or leaking in many places at once are better addressed from outside, and we'll say so during the inspection.
It depends heavily on how many entry points there are and what's causing them, so a single crack injection sits at the low end while multiple leaks combined with drainage corrections run higher. Estimates are free, and you'll get more than one option with pricing attached to each so you can decide what makes sense.
Not always. Plenty of leaking cracks are shrinkage cracks that formed as the concrete cured and never threatened the structure at all. Horizontal cracks, walls with visible inward movement, and cracks that keep widening are different matters, and those get evaluated more closely before we recommend anything.
Scheduling for homes around Marietta, Smyrna, Powder Springs, and the nearby communities usually happens within a few days, and we work Monday through Saturday. Our team doesn't offer emergency service, so anyone dealing with active flooding should shut off the water source if possible and reach us during business hours.
