Water shows up in a basement long after the real problem started outside. By the time you're seeing a damp patch on the wall, a white chalky film on the block, or a puddle that reappears after every heavy rain, moisture has already been working its way through the concrete for a while. A&A Waterproofing has been handling foundation waterproofing for homeowners in Marietta, GA, and nearby areas since 1996, and we deal with it where the trouble actually begins rather than covering it up on the inside. Sealing the wall from the exterior means water stops before it has a chance to reach anything you care about.
A&A Waterproofing is a veteran-owned foundation waterproofing and repair company based in Marietta, GA, owned and operated by Allen Aschwege. Our team specializes in exterior work that stops water intrusion and repairs existing foundation leaks. That involves excavating along the foundation wall, sealing cracks and other entry points, applying waterproof membranes and coatings, and improving drainage so runoff moves away from the structure.
The problem usually announces itself quietly. A musty smell in the lower level, efflorescence powdering the block, moisture wicking up through the floor, or an actual trickle running down the wall after a storm. Left alone, that moisture damages finishes, feeds mold, and eventually starts working on the structural integrity of the wall itself.
What's causing it sits on the other side of that wall. North Georgia clay soaks up rainfall and holds it, then presses against your foundation with real force. Concrete and block are porous by nature, so saturated soil pushing moisture inward will find the pores, the tie holes, the cold joints, and any hairline crack that already exists. Poor grading, short downspouts, and clogged or absent drainage make the situation considerably worse by keeping that soil wet.
Our fix works from the outside. We excavate down along the foundation to expose the wall, clean and prepare the surface, then repair any cracks or leak points we uncover. From there, a foundation waterproofing membrane goes on along with a protective coating, creating a continuous barrier between the soil and the concrete. We finish by improving the drainage, which can mean footing drain lines, corrected grading, and extended downspouts so water leaves the area instead of collecting beside the house.
The result is a waterproof exterior foundation that keeps water on the outside where it belongs. Homeowners get a dry lower level they can actually use, framing and finishes that stop absorbing moisture, and a repair that holds up rather than one they revisit every spring. Backing that work with our warranty coverage is how we stand behind it.
Every property drains a little differently, so here's a look at the pieces that typically make up a project.
Sealing a wall accomplishes far less if water keeps collecting against it, which is why drainage is part of nearly every job we take on. Depending on the site, our crews install footing drains, correct the grade so the ground slopes away from the home, and extend downspouts and discharge lines well clear of the foundation.
Reaching the exterior wall means opening up the soil along it, and careful excavation protects your landscaping, walkways, and utilities in the process. Our team digs down to the footing so the entire below-grade surface is accessible, since a barrier applied to only part of a wall leaves an obvious way in. Backfilling gets handled properly at the end so the ground settles the way it should.
Active leaks get addressed before anything else goes over the wall. Cracks, tie holes, and cold joints all get sealed using the method that suits the situation. This stage of foundation repair and waterproofing frequently reveals more about the underlying issue than anything visible from inside.
Over the membrane, a protective coating adds another layer of defense and shields the system from damage during backfill. Products we use are rated for below-grade conditions and hold up against the constant moisture and soil pressure a foundation deals with year-round.
The membrane forms the actual barrier between wet soil and your foundation, and proper installation matters more than the product itself. We bond it across the prepared wall with attention to seams, corners, and the transition down at the footing, since those are the spots where shortcuts show up later. Quality house foundation waterproofing comes down to how carefully this layer goes on.
Stopping future problems is the whole point, so we look at the property as a system rather than treating one wet spot. Grading, gutters, downspout placement, soil conditions, and drainage all get evaluated during the estimate, and we'll tell you which ones are contributing. Among foundation waterproofing companies in the area, we'd rather point you toward the smaller fix that solves the problem than sell you the largest job on the list.
Damp air, chalky white residue on the block, and a dehumidifier that never shuts off are all signals worth taking seriously. Basement waterproofing from us involves interior drainage along the perimeter, sealing and repairing spots where water is actively getting through, controlling humidity, and adding a pump if the drainage has nowhere to run on its own.
Foundation trouble rarely announces itself all at once, showing up instead as a hairline crack here and a stubborn window there. Our foundation repair services begin with a thorough look at the whole picture, then move to the appropriate fix, whether that means injecting a crack that's letting water through, bonding carbon fiber straps across a wall taking pressure from the soil, stitching a section back together, or bracing a wall that has begun to bow.
Roughly half the air in your living space comes up from below, which explains a lot about how a damp crawl space affects the rest of the house. With crawl space repair and encapsulation, we clear out debris, seal the ground and walls behind a thick liner, install drainage and a dehumidifier to keep conditions steady, and apply fungicide treatments or add vent fans where needed.
Downspouts that dump straight onto the ground beside the house create a small flood at the foundation every single time it rains. Our French drains and yard drainage work redirects all of that, using buried gravel-and-pipe drain lines, grading adjustments to level out the low spots collecting water, extended pipes that carry runoff well away from the structure, and driveway drains for the paved areas sending water back toward the home.
The lowest point of a basement or crawl space is where water ends up, and something has to move it out from there. A sump pump installation with us includes fitting a new pump, replacing an older unit that's struggling or already failed, and connecting it to the drainage system so water reaches the pit and leaves the property.
Doors that stop latching, gaps opening above trim, and stair-step cracking in the mortar joints usually mean a section of the home has dropped. Foundation stabilization solves it by transferring the weight onto helical piers anchored in stable soil below, then lifting and correcting the settled area and adding load-bearing support to hold everything in place.
Sagging floors typically come from beams, joists, or piers underneath that have taken on moisture and lost their strength over the years. Floor leveling and structural repairs from our crew involve jacking the floor back to where it should sit, installing proper crawl space support systems, reinforcing or replacing compromised beams, and repairing joists showing rot or damage.
Bringing in a waterproofing company to dig up the side of your house is a big decision, so here's what working with us looks like.

Qualifying projects carry warranties running from 10 years all the way to lifetime coverage, depending on the specific repair.
Permit requirements depend on the work involved, especially when a project includes structural repairs, major excavation, plumbing, or site development. The City of Marietta requires permits for many building alterations and repairs, so homeowners should verify the project requirements before work begins.
Contractors typically identify the entry point, excavate the affected area, prepare and repair the wall, apply a foundation waterproofing membrane or coating, and improve the surrounding drainage. A complete system may also use a drainage layer or footing drain to move groundwater away from the wall.
The timeline depends on the number of walls involved, excavation depth, soil conditions, weather, and the repairs needed before crews apply the waterproofing materials. A smaller repair may finish quickly, while a project that requires extensive excavation and drainage work can take several days or longer.
Poor grading, short downspouts, foundation cracks, saturated soil, and heavy rain can push or direct water toward the house. Clay-rich Georgia soil may hold moisture for several days, which can keep the ground around a foundation wet after the storm passes.
Exterior foundation waterproofing blocks and redirects water before it enters the building, while an interior drain system collects water that reaches the inside perimeter. A contractor should choose the method after evaluating the leak source, foundation design, access, grading, and groundwater conditions.
