Basement Waterproofing Tips From Residential Waterproofing Experts

July 10, 2026

Keeping your basement dry is one of the most important parts of residential waterproofing, and Atlanta, GA, homeowners face some unique challenges that make it worth understanding well. Atlanta's heavy spring rainfall, high humidity, and clay-heavy soil all put pressure on home foundations year-round. Knowing the difference between what you can handle yourself and when to call a professional can save you time, money, and stress.


Why Atlanta Basements Are Especially Vulnerable to Water Damage


Atlanta basements face water pressure from multiple directions. The city receives frequent heavy rainfall, especially in spring and summer. On top of that, the clay soil common throughout the metro area expands and contracts with moisture, which can shift and crack foundations over time.


Hydrostatic pressure is the main force pushing water into basements. When water builds up in the soil around your foundation, it looks for the path of least resistance. That path often leads straight into your basement walls or floor.

What Can Homeowners Do on Their Own?


Simple maintenance steps can reduce water risk before it becomes a bigger problem. These are tasks most homeowners in Atlanta, GA, can handle without professional help.


  •  Keep gutters and downspouts clear of debris so water drains away from the foundation.
  • Grade soil around the home so it slopes away from the foundation at a gentle angle.
  • Check window wells for standing water and add gravel or covers as needed.
  • Inspect visible foundation walls for small cracks and monitor them over time.


These DIY steps can slow moisture entry. However, they may not address deeper drainage or pressure issues already present in the foundation. For a more complete approach to home waterproofing, professional evaluation is often the most reliable next step.

When Does Basement Waterproofing Require a Professional?


Professional basement waterproofing is typically needed when water is actively entering the space, walls show bowing or staining, or a musty smell persists despite surface-level fixes. Hardware store sealants and waterproofing paints may help reduce odors temporarily, but they often cannot hold back sustained hydrostatic pressure. Over time, water pressure can break those seals and allow moisture to return.


A professional assessment can identify whether the source of the problem is interior drainage, exterior water intrusion, foundation movement, or a combination of all three. Each home is different, and the right fix depends on a proper diagnosis.


Interior vs. Exterior Waterproofing Solutions


Interior systems manage water that has already entered the foundation area. They typically involve drainage channels installed along the perimeter of the basement floor, paired with a sump pump to move water out. Exterior solutions focus on preventing water from reaching the foundation at all, using membranes, drain mats, and French drains. Both approaches may be appropriate depending on the severity and source of the water intrusion.


Residential waterproofing decisions should never be based on a one-size-fits-all approach. The soil type, foundation material, and water source all influence which method may work best for a given property.

By Admin • May 12, 2016
You can walk down the isle of any hardware store in any town and find a hundred methods, solutions, and quick fixes for waterproofing your basement. Each and every one of them may work for a period of time. The one condition that these methods do not take into account is pressure. Pressure exerted by the water is what causes it to flow into our homes. Hydrostatic pressure and lateral pressure force the water to move somewhere—often into our basements. At Sundry Waterproofing, we offer permanent solutions for waterproofing your basement and keeping it dry once and for all. There are several main types of basement waterproofing methods. Interior sealants and coatings found in hardware stores repair cracks only for a matter of time—until water pressure breaks the seal. People often go this route because it’s easy and affordable. The problem is it is only temporary.

Can I waterproof my basement with paint?

You’ve found water in your basement and now you’re looking for a solution. You may have already called a local waterproofing contractor to get an estimate for your wet basement and the shock of the cost may have sent you directly to your local home center to find a more cost effective solution to fix it yourself. The most common do-it-yourself basement waterproofing products available in home centers are waterproofing paints. This cheap, easy to apply fix peaks the interest of my homeowners looking to waterproof their basement without the big cost of hiring a PRO, but does it work? Will it last? Can it actually waterproof your basement? Well, lets break it down… Pros of Waterproofing Paints: Reduces fungal smells by creating an airtight shell over the surface of the basement walls. Lowers the radiation of humidity by locking the moisture behind the paint surface. Dampproofs the walls by preventing moisture from passing into the interior of the basement. Cons of Waterproofing Paints: Will not waterproof a basement – Waterproofing paints are designed to push hold or plug moisture, but it does not properly manage the water entering the basement, therefore, it is not a long-term solution to dry up a wet basement. Blistering and shelling – Paint rely on its bond to the wet surface and eventually that bond will way. Over time as the lime in the cement begins to get wet, a white efflorescence will begin to grow between the surface of the concrete and paint creating a large boil or blister, which flakes and shells off. May generate greater hydrostatic pressure – Block wall foundations have hollow cavities that build up with hydrostatic pressure when moisture is present. Waterproofing paints attempts to hold back moisture, which causes a deeper build up of water and causes greater pressure inside the wall. Bottom line: Waterproofing paints don’t waterproof your basement, but they will help reduce odors and lower the radiation of humidity in the basement.
