Digging up the outside of a house isn't always realistic. Mature landscaping, a patio or driveway poured tight against the wall, utilities buried along the side yard, or a budget with a firm ceiling can all take exterior excavation off the table. None of that means you have to keep living with a wet lower level. A&A Waterproofing has been handling interior basement drain system installation for homeowners throughout Marietta, GA, and the towns nearby since 1996, and a properly built perimeter system intercepts water the moment it arrives and routes it back out before it ever spreads across your floor.
Under owner Allen Aschwege, A&A Waterproofing has run as a veteran-owned waterproofing and foundation repair contractor from its Marietta, Georgia, base since 1996. Interior drainage sits at the center of what our crews do below grade, and that work involves opening a channel along the perimeter where the floor meets the wall, setting perforated pipe in washed gravel, adding wall drainage where block cores need to release trapped water, routing everything to a gravity outlet or a sump basin, and restoring the concrete when the system is in. Anything already built is work we'll take, while new construction is not. Homeowners and commercial property managers around Marietta and the nearby towns make up our customers, and an estimate never carries a charge.
Water rarely arrives through the middle of a basement floor. Homeowners describe a dark line following the base of the wall, dampness that shows up in the same corner every time, moisture wicking a few inches up the block, or a slow spread across the slab that starts at the edges. Anything stored along the perimeter takes the hit first, and the humidity that comes with it settles into the whole lower level.
The reason has to do with how a basement is built and what surrounds it. Your floor slab and your walls are separate pours, and the seam between them is a natural opening. Add the hollow cores in a block wall, mortar joints that soften over decades, and the saturated clay soil sitting outside pressing inward, and water follows the path of least resistance straight to that seam. Rain that soaks the ground around a Marietta home has nowhere to drain quickly, so pressure builds against the wall and stays there.
Our installation works with that reality instead of against it. Crews break out a strip of concrete around the interior perimeter, excavate below slab level, and lay perforated pipe surrounded by washed stone that lets water in from every direction. Where block walls are holding water in their cores, we add wall drainage so that moisture releases into the system rather than seeping through the face. Everything slopes toward a discharge point, whether that means a gravity line running to daylight or a sump basin with a pump, and fresh concrete closes the trench once the system is tested.
Once it's running, water never gets the chance to reach open floor. The slab stays dry, humidity drops enough to notice within the first week or two, and storage stops being something you elevate on pallets. Homeowners planning to finish the space can move forward knowing exactly what sits underneath, and the warranty paperwork gives you something concrete to hand a buyer later on.
Interior drainage solves a wet basement in a way that suits plenty of properties better than digging outside, and these are the returns it delivers.
Intercepting moisture at the wall and floor seam means it enters a pipe rather than a room. That single difference determines whether a storm produces a minor event nobody notices or a Saturday spent with a wet vacuum. Perimeter coverage handles every wall rather than the one that happens to be leaking today.
Rain, cold, and saturated ground stop exterior projects in their tracks, while an interior system can go in during any season. Scheduling gets far more predictable as a result, which matters when someone has a renovation timeline to meet. Georgia winters rarely interfere with this kind of installation at all.
Skipping excavation, landscape restoration, and hardscape removal takes a substantial amount off the total. Properties where a deck, driveway, or retaining wall sits against the foundation would otherwise face demolition costs on top of the waterproofing itself. Homeowners frequently find this route brings a solution into reach that seemed out of budget.
Basements sitting below any available gravity outlet need a pump, and a perimeter drain feeds one perfectly by delivering collected water straight to the basin. Sizing the pump to the volume the property actually produces is part of the design conversation. Backup options come up as well, since storms and power outages have a habit of arriving together.
Qualifying interior systems are covered for a decade at minimum, with lifetime terms available depending on what the installation involved. Everything gets put in writing rather than promised verbally. That paperwork answers the basement moisture question buyers always ask when a home goes on the market.
Perimeter drainage frequently pairs with other work we perform below grade, and these related pages cover the rest.
Individual entry points sometimes call for a targeted fix instead of a full system, and our basement leak repair service seals cracks, mortar joints, window well leaks, and pipe penetrations using the appropriate method for each. Identifying the source is what keeps a small repair from becoming an unnecessary large one.
Drywall, flooring, and framing change how a project has to be approached, and our finished basement waterproofing work is built around protecting the investment you already made downstairs. Access gets planned in advance so disruption stays contained.
Interior drainage represents one path among several under our broader basement waterproofing services, which cover moisture control, water management, leak repair, and pump integration. Which combination suits a property depends on its layout, soil, and how much water it takes on.
Anyone cutting concrete inside your home should be someone you feel good about hiring, so here is what you can expect from us.
Allen looks at where the water shows up, how the walls are built, what the exterior grading is doing, and where a discharge point could realistically go. Some homes turn out to need far less than a full perimeter, and we say so. The estimate includes the reasoning, not just a number at the bottom.
Pipe capacity, stone volume, discharge routing, and pump selection all get matched to what your property actually deals with during a heavy rain. Undersized installations are the most common failure we're called out to fix. Building for real conditions costs a little more up front and prevents a second project later.
Breaking out a slab makes a mess, and putting it back properly is part of the job rather than an extra line item. Debris leaves with our crew, the new concrete gets finished to blend with what's there, and the space is usable again when we pull out. Dust control gets handled during the work as well.
There's no charge for the visit, the inspection, or the quote. Acorn Finance spreads the cost when a project lands at an inconvenient stretch, and EMTs, veterans, firefighters, active-duty military, and police officers take 10% off under Hometown Heroes.
This is a veteran-owned company that has operated in the Marietta area since 1996, carrying forward a family business that started in Missouri roughly twenty years before that. Longevity like that only happens when customers keep sending their neighbors.
Most residential perimeter systems go in within two to four days, with the exact timeline depending on how much wall we're following, whether a sump basin is part of the scope, and how accessible the perimeter is. Basements packed with storage take longer because clearing the working area comes first. Our crew will give you a schedule during the estimate.
Yes, and block walls are among the most common we work on around here. Because block is hollow, water frequently collects inside the cores and seeps out through the face, so we add wall drainage that lets those cores release into the perimeter pipe. Poured concrete walls get a slightly different detail at the seam.
Homes with enough elevation can discharge by gravity to a lower point on the property, which is the simplest arrangement and needs no power. Lots that sit flat, which describes plenty of properties around Marietta and Smyrna, require a sump basin and pump to lift the water out. Either way, the discharge gets routed well away from the foundation so it doesn't circle back.
Concrete cutting is loud while it's happening, and there's dust involved, so we take steps to contain it and keep the mess to the work area. Families usually stay in the home throughout. The noisiest portion typically lasts a day or less, and everything upstairs remains untouched.
Requirements vary across the counties we serve, and interior waterproofing often falls under repair rather than structural work. Our team checks what applies in your jurisdiction before we start and handles anything required. Adding electrical for a sump pump can change the answer, and that portion needs a licensed electrician since we don't install dedicated circuits.
