Basement leaks and dampness are common in Kennesaw, where shifting clay soil and heavy rain make water intrusion a real risk. At '58 Foundations & Waterproofing, we install proven drainage and waterproofing systems to keep your basement dry.
Even a small leak can lead to costly repairs if left unchecked. In Kennesaw, heavy rains, clay-heavy soils, and seasonal humidity make basements especially vulnerable to water intrusion. Whether you're seeing puddles after a storm or just noticing that familiar musty smell, the signs of a moisture problem can be subtle at first, but they only get worse with time.
At ’58 Foundations & Waterproofing, we install long-lasting basement waterproofing systems that do more than just patch symptoms. From capturing groundwater at the cove joint to protecting your basement from structural damage, our drainage and sealing solutions are built for Georgia homes and backed by our Life-of-the-Structure Warranty.
Kennesaw’s location in northern Georgia means homeowners often deal with a mix of red clay soil and heavy seasonal rainfall. While that combination supports lush landscaping, it also creates ideal conditions for water to seep into basements. Clay soil absorbs water slowly but holds it tightly, which increases hydrostatic pressure around your foundation after every storm.
The terrain throughout Cobb County features rolling hills and uneven grading, which can lead to water pooling near homes. If your property lacks proper drainage or your gutters are clogged or undersized, water may begin pushing against your basement walls or leaking in through floor cracks and cold joints. Even minor settling over time can open up new paths for water intrusion.
Many homes in the Kennesaw area were not originally built with full waterproofing systems in place. Over time, as weather patterns shift and structures age, once dry basements can become vulnerable to leaks, musty odors, and structural damage.
You don’t need standing water to know your basement has a moisture problem. In fact, most water issues begin subtly, long before major flooding occurs. If you notice these symptoms in your Kennesaw home, it may be time to call a basement waterproofing company:
Musty odors or humid air
Basements should feel cool and dry. If the air smells stale, damp, or moldy, it could mean water vapor is seeping in through unsealed walls or the slab. This is common in homes near Noonday Creek or areas with heavy tree cover and poor airflow.
Staining or discoloration on walls
White, powdery marks (efflorescence) or brown stains along basement walls indicate past water intrusion, even if it's not actively leaking. These stains often appear after seasonal rains or periods of high humidity.
Cracks in walls or floors
Small hairline cracks might seem harmless, but they can allow water to enter and expand over time. Cracks caused by hydrostatic pressure or foundation settlement are common in older homes throughout Cobb County.
Peeling paint or bubbling drywall
Finishing materials like paint or paneling can hide moisture issues until they begin to fail. If you notice bubbling, peeling, or warped surfaces, moisture may be building up behind your walls.
Rust or corrosion on appliances or metal surfaces
A damp basement creates a harsh environment for metal. If your water heater, furnace, or tools stored downstairs show early signs of rust, it could be due to long-term exposure to high humidity or hidden leaks.
At ’58 Foundations & Waterproofing, we customize every basement waterproofing system to the home. From capturing groundwater to protecting walls and floors, our solutions are engineered for Kennesaw’s red clay soil, rolling terrain, and heavy seasonal rains. Whether your basement is damp, musty, or already showing signs of damage, we’ll protect it from the ground up.
Here’s what we offer:
Interior Drainage System Installation
We install high-capacity interior drainage channels at the base of your basement walls to intercept groundwater before it seeps in. These systems relieve hydrostatic pressure and direct water to a sump pump, helping prevent flooding, foundation cracks, and long-term structural damage.
Basement Wall Membranes
Sealing vulnerable areas keeps moisture from entering through porous concrete or cracks. Our team applies industry‑leading vapor barriers where necessary to stop hidden leaks and protect finishes from damage.
Sump Pump and Battery Backup Installation
A reliable sump pump is the heart of any basement waterproofing system. We install high‑performance pumps, with optional battery backups, to keep water moving out of your home even during power outages or heavy storms.
Humidity and Air Quality Control
Kennesaw’s humid climate can make basements feel muggy even without visible leaks. We install basement‑rated dehumidifiers to reduce condensation, protect stored belongings, and improve air quality throughout the house.
Structural Reinforcement and Crack Repair
If moisture has caused cracks or weakened areas of your basement walls or slab, we provide targeted repairs and reinforcement to restore stability. Addressing these problems early prevents small leaks from becoming major structural issues.
Every system we install is backed by our Life‑of‑the‑Structure Warranty and built to last through Kennesaw’s soil and weather conditions.

Sump pumps are one of the most important components of a basement waterproofing system, especially in Kennesaw, where sudden downpours and waterlogged clay soils can lead to fast-rising groundwater and interior flooding.
Unlike surface drainage or cosmetic fixes, sump pumps actively remove water from beneath your home and redirect it away from the foundation. Installed as part of a complete waterproofing system, a sump pump protects your structure from water intrusion, preserves indoor air quality, and helps maintain a dry, usable basement space year-round.
A sump pump system is designed to collect groundwater before it enters the basement and pump it away from the home’s foundation. A typical installation includes:
Kennesaw’s red clay soil holds moisture longer than sandy or loose soil, which increases the risk of hydrostatic pressure and water infiltration. Combined with the region’s frequent heavy rains and seasonal storms, this makes sump pumps a smart investment for local homeowners looking to avoid basement flooding.
A sump pump system helps by:
Across Cobb County, from downtown Kennesaw to Acworth and Marietta, homeowners trust sump pump systems as the heart of a reliable basement waterproofing strategy.
