Plenty of homeowners around here have quietly written off their lower level. The boxes go up on pallets, the dehumidifier runs all summer, and nobody puts a rug down there anymore because everyone knows what happens after a hard rain. At A&A Waterproofing, we've been solving that for homeowners with basement waterproofing in Marietta, GA, and nearby areas since 1996, and the fix is usually more affordable than people expect once they finally ask. Getting water under control turns that space back into square footage you paid for and can actually use.
Allen Aschwege owns and operates A&A Waterproofing, a veteran-owned waterproofing and foundation repair contractor working out of Marietta, GA. Our team handles both finished and unfinished basements, installing interior drain systems, repairing leaks where they're found, managing moisture and humidity, and integrating sump pumps when a property can't drain by gravity.
The signs are hard to miss once you know them. Damp carpet along one wall, a chalky white residue on the block, warped baseboards, a smell that never quite goes away, or standing water on the floor the morning after a storm. Whatever's stored down there takes the damage first, and the mold that follows affects the air in the whole house.
The reason it keeps happening comes down to hydrostatic pressure. Rain saturates the clay soil surrounding your home. That soil holds water against the walls, and the pressure pushes moisture through every available opening. Concrete block and poured walls are porous, so water finds the cold joint where the wall meets the floor, hairline cracks, mortar joints, and the spot where a pipe passes through. Nothing about this is unusual, and it happens to well-built homes constantly.
Our approach captures the water rather than fighting the pressure head-on. We open a channel along the interior perimeter at the base of the wall, install a drain system in gravel that collects water as it arrives, and pipe it to a discharge point or a sump basin. Any active leaks get sealed, we address moisture and humidity so the air stays comfortable, and the concrete gets restored over the new system.
The result is a basement that stays dry through the worst storms Georgia sends. Stored items stay safe, the musty smell disappears, finished spaces stop taking damage, and the humidity drops enough that the rest of the house feels better too. Our warranty coverage backs the system, so this becomes a repair you handle once.
Every basement presents its own set of conditions, so here's a breakdown of what a typical project can include.
Liquid water gets the attention, but humidity does plenty of damage on its own to stored belongings, framing, and air quality. Dehumidification, vapor barriers, and sealing where appropriate all help hold conditions steady through a Georgia summer.
Interior drainage does its job better when the water outside is also going somewhere sensible. During your estimate, we look at grading, downspouts, and how the property sheds rainfall, then tell you which exterior corrections would reduce the load on the system. Solving part of it outdoors is often the least expensive option.
Active water entry points get sealed before the rest of the system goes in. Cracks in the wall, gaps around pipe penetrations, and failing mortar joints all get repaired using whatever method suits that specific spot, and this part of basement wall waterproofing often reveals what's really going on outside the house.
The heart of most waterproofing basement projects is a perimeter drain that intercepts water at the joint where the floor meets the wall. Our team cuts a channel around the interior, sets perforated pipe in gravel, and routes everything toward a discharge point so water never reaches the open floor. Concrete goes back over the top, leaving a clean surface behind.
Properties that sit too low for gravity discharge need a pump handling the work instead. We set a basin at the low point, tie the drain system into it, and install a pump sized for the volume your home actually deals with, along with a discharge line carrying water well away from the foundation. Battery backup options come up in most of these conversations, since storms and power outages tend to arrive together.
Drywall, flooring, and framing complicate a project, and our crews work carefully to limit disruption to spaces you've already invested in. Access points get planned ahead of time, materials get protected, and everything gets put back together properly once the drainage system is functioning.
Bare block and exposed concrete make the work more straightforward, and they also make it a smart time to get ahead of the problem before you finish the space. Our systems install cleanly in unfinished areas, and basement floor waterproofing handled now means you can build out down there later without worrying about what's underneath.
Georgia gets a lot of rain in short, heavy bursts, and the ground next to your house absorbs more of it than most people realize. Our foundation waterproofing work starts by exposing the exterior wall, then applying a waterproof membrane and protective coating across it, sealing off any point where water has been getting through, and correcting the drainage so runoff moves away instead of settling beside the footing.
A wall pushing inward or a crack that keeps growing means soil pressure has outmatched the concrete. We approach foundation repair by inspecting the structure first and identifying what's driving the damage, then applying the fix that suits it: sealing cracks with injection, adding carbon fiber straps that reinforce the wall against further movement, stitching a break back together, or bracing a bowing section before it worsens.
Anything stored in a bare crawl space, including the joists and subfloor above it, sits in whatever moisture the ground gives off. Our crawl space repair and encapsulation crew shuts that down by cleaning the area, covering the soil and walls with a sealed vapor barrier, adding drainage and a dehumidifier that keeps the space at a steady dryness, and treating for fungus or installing vent fans depending on what we find.
Rain that has nowhere to go collects in the low spots of a yard and slowly soaks toward the lowest point on the property, which is often your foundation. Our French drains and yard drainage solutions take care of that with perforated drain lines set in gravel, regrading to eliminate the dips holding water, longer downspout and pipe runs that carry discharge well clear of the house, and driveway drains for paved areas funneling water back toward the structure.
Not every property sits high enough for gravity to carry water away, and that's where a pump earns its keep. A sump pump installation from us covers new systems, replacements for units that have burned out or can't keep up during heavy rain, and integration with your existing drain lines so water flows to the pit and out of the building.
When one part of a home settles faster than the rest, the whole structure has to absorb the difference, and it shows up in cracked brick and doors that won't latch. Foundation stabilization corrects the problem by installing helical piers that reach past the unstable soil to firmer ground, lifting the settled portion back toward its original elevation, and adding load-bearing support that carries the weight from that point forward.
Years of moisture in a crawl space will soften beams and joists until the floor above starts giving way underfoot. Floor leveling and structural repairs address that directly through floor jacking to bring the sagging area back up, new support systems set on proper footings beneath the crawl space, beam reinforcement where the framing has weakened, and joist repair for anything showing rot.

Professionals can often preserve much of a finished basement, but they may need to remove flooring, lower wall sections, or trim near the affected perimeter. The amount of disruption depends on the leak location and whether the basement waterproofing plan uses crack repair, interior drainage, a sump pump, or exterior work.
An interior drain collects water along or beneath the basement floor and directs it toward a sump basin or another approved outlet. When gravity can't carry the water away, a sump pump moves it outside before it spreads across the floor.
Treat basement flooding as urgent when rising water approaches electrical equipment, damages finished materials, or continues entering the home. Stay out of standing water near electricity, and begin safe drying as soon as possible because wet materials can support mold growth within 24–48 hours.
Water stains, damp walls, peeling finishes, musty odors, floor seepage, efflorescence, and recurring puddles can all point to a moisture problem. A basement waterproofing inspection helps trace the water to cracks, wall joints, surface runoff, groundwater, or an inadequate drainage system.
The right solution depends on whether water enters through a wall crack, the wall-floor joint, the slab, a window opening, or the surrounding grade. After identifying the source, contractors may use leak injections, interior drains, sump pumps, exterior barriers, grading corrections, or a combination of methods.
