Built on Honor. Driven by Service. Committed to Protection.
Georgia rain has a way of finding every weak spot in a house. It shows up as a damp basement floor after a heavy storm, a musty smell drifting out of the crawl space, or a puddle in the yard that sits there for days. Water is patient, and given enough time, it'll work its way into your foundation, warp your floors, and turn a small repair into a very large one. At A&A Waterproofing, our crew has spent a long time helping homeowners get ahead of that, and our approach starts with explaining what's actually happening under your house before anybody talks about fixing it. We've been the waterproofing service Marietta, GA, and nearby areas have counted on since 1996, and whatever's letting water in, we've got a way to shut it down.

Most water problems start on the outside of a house, which is why our foundation waterproofing work happens where the trouble begins. Depending on what we find, that can mean excavating down to the footing, sealing the wall with waterproof membranes and coatings, repairing active leaks, and improving the drainage so rainwater heads away from the house instead of collecting against it. Handling it from the exterior stops water before it ever reaches your living space, and that's usually the difference between a one-time repair and an annual ritual with a shop vac.
Basement waterproofing is the other half of the equation, and it works for finished and unfinished spaces alike. Our interior drain systems capture water and route it out, and we take care of basement leak repair, moisture control, and overall water management, along with tying in a sump pump when the layout calls for one. If you've been storing boxes on pallets or keeping a dehumidifier running year-round, this is the work that gives you the square footage back.
When water has been at it for a while, or when the soil around the house shifts, the foundation itself starts showing wear. Our foundation repair work begins with an inspection, then moves to the fix that actually suits the problem: crack repair and injections for leaking cracks, carbon fiber straps and stitching to reinforce a wall that's under pressure, and stabilization for walls that have started to bow. Allen has spent decades reading these situations, and he'd rather explain your options and let you pick than talk you into the biggest job on the list.
Our goal is to help you understand the problem, compare sensible repair options, and choose an approach that works for your property and budget.
With more than three decades of hands-on work behind us, we've seen just about everything a Georgia basement can throw at us, and we'd rather teach you what's happening down there than hand you a bill you don't understand.

Common warning signs include damp basement walls, standing water, musty odors, mold growth, crawl space moisture, water stains, and puddles collecting near the foundation. A waterproofing service professional can inspect the property, identify where the water is coming from, and explain which repairs may help keep the problem from spreading.
A waterproofing service helps prevent or manage water entering through foundation walls, basement floors, crawl spaces, and surrounding soil. Depending on the source, the solution may involve exterior membranes, interior drain systems, sump pumps, vapor barriers, foundation leak repairs, grading corrections, or French drains.
Heavy rain, humid conditions, poor grading, short downspouts, foundation cracks, and saturated soil can allow water or moisture to collect around and beneath a home. As pressure builds against the foundation, water may seep through walls, cracks, joints, or the basement floor.
A waterproofing service typically evaluates water intrusion, moisture, drainage, and related foundation concerns before recommending a repair plan. Services may include foundation and basement waterproofing, crawl space encapsulation, leak repair, drainage improvements, sump pump installation, and structural foundation repairs.
The right method depends on where the water is entering, how the property drains, and whether the moisture affects a basement, crawl space, or foundation wall. Exterior waterproofing may help block water before it enters, while interior drains, sump pumps, encapsulation, and yard drainage can manage water and moisture in other areas.
