Below the mountain

Kennesaw basements take the runoff from the hills.

Kennesaw spreads out below a 1,808 foot mountain, and the town's rain gauge southwest of downtown averages about 53 and a half inches a year. The most common soil near downtown is Madison and Pacolet on 10 to 25 percent slopes, much of it eroded until the red clay subsoil sits at or near the surface. That dense clay sheds a hard rain quickly, then holds whatever soaks in against anything buried downhill, including a basement wall. In the creek bottoms, frequently flooded Cartecay soil keeps a seasonal water table about a foot down. Hill or hollow, the water has a way to a Kennesaw basement.

Butler Creek past the 500-year mark
On September 21, 2009, Butler Creek near Kennesaw rose to 14.27 feet, over its 12 foot flood stage, at 6,760 cubic feet per second. The USGS said its flooding greatly exceeded the 500-year flood.
Noonday Creek the same day
The Noonday Creek gauge at Shallowford Road peaked at 11,300 cubic feet per second that same day. When creeks run that high, the low ground beside them stays soaked well after the crest.
Basements turning 30
Three in ten Kennesaw homes were built in the 1990s. Footing drains, sump pumps and exterior coatings from that decade are old enough to clog, wear out or quit, often without warning.

Slope and runoff

How the lot falls, where water runs in a storm, and where gutters and downspouts empty.

Basement walls

Seepage at the joint, damp drywall, white residue on bare walls and cracks that weep.

Floor and sump

Water at the slab edges, how often the pump runs, and whether a backup is in place.

Common basement water problems in Kennesaw

Four ways a Kennesaw basement shows water.

Eroded red clay on hillsides and wet creek bottoms give Kennesaw basements a familiar set of problems. These four come up most, and each one points the diagnosis somewhere different.

Water after a thunderstorm

On slopes where the red clay subsoil is at the surface, a hard storm runs off fast toward the house. A basement built into that slope gets wet along the buried wall within hours, at the joint where wall meets floor.
Full diagnosis: water after rain

A white crust on the wall

Water moving through a block or poured wall deposits minerals that dry into a white, crusty film. On the unfinished side of a Kennesaw basement, that film shows where moisture is getting through.
Full diagnosis: efflorescence

A sump that never rests

Near the creek bottoms, Cartecay soil holds a water table about a foot below the surface for part of the year. A pump that runs through every wet week is handling groundwater and needs to be up to it.

A musty finished basement

With a median build year of 1998, a typical Kennesaw basement is now well over 20 years old. In a finished one, a musty smell or spots low on the drywall mean damp is reaching the room, and cleaning will not last until the water stops.
Full diagnosis: mold and mildew

The FoundationRX Diagnostic Method

How we diagnose basement water in Kennesaw.

A lot of waterproofing companies show up to sell you the most expensive system they install. We show up to figure out how water is actually getting into your basement first, then prescribe the system that stops it, and tell you straight, even when the answer is "you don't need as much as you were told."

01

Diagnose

A free in-home inspection by someone who does this work. We trace where the water is coming from, inside and around the home, and walk you through what's actually driving it.

02

Prescribe

The right waterproofing system for how water is getting in, not the priciest package. A plain-English explanation and a fair price in writing. You decide on your own time.

03

Treat

Dependable work by our own local crew, on time, cleaned up after themselves. We keep you in the loop until the basement is dry and we have walked the finished job with you.

A lot of companies sell you a system. We diagnose first, then prescribe only what your basement actually needs to stay dry. That's the difference between an honest local team and a sales quota from out of town.

How we keep basements dry

Basement waterproofing methods for Kennesaw homes.

Runoff hitting a buried wall and groundwater rising in a creek bottom need different fixes. These are the four methods we prescribe from, and the diagnosis of your Kennesaw basement decides which ones it needs.

Interior Drainage

A drain channel installed along the inside base of the walls takes in the runoff that pushes through the joint and sends it to a sump before it reaches the floor or the drywall.

Best for: storm seepage along a buried wall.

Sump Pump Systems

The pit collects the drained water and the pump lifts it out and away from the house. A battery backup keeps the pit from overflowing when a storm cuts the power.

Best for: lots near the creek bottoms and aging pumps.

Wall Vapor Barrier

A sealed liner on the walls keeps wall moisture and musty air out of the room, and gives an unfinished basement a bright, clean surface.

Best for: damp walls, white crust and musty storage space.

Grading & Downspout Fixes

Reshaping a hillside yard so water falls away from the house, and piping downspouts past it, keeps storm runoff off the clay against the basement.

Best for: leaks that start after storms on one side.

What homeowners say

In their own words.

Misty Little
“This company came out to my home and did a great job. They took my very nasty crawl space that was full of water and transformed it into a dry healthy place. My encapsulation of my crawl space looks exactly like the pictures they posted. My only regret is not doing this sooner! From the office to the crews, it was a smooth, enjoyable experience.”
K. Schantzer
“From start to finish the process was great. FoundationRX repaired my foundation and installed an encapsulation system with drainage in my crawl space. My home no longer smells from the moisture! Would highly recommend FoundationRX for all your home foundation, water intrusion issues. Reasonable prices as well!”
Bobby Stinson
“Had Ryan come do an estimate and I had severe water damage. The estimate was great so I hired them, these guys are professionals, they got rid of all the damage replaced all the damage seals floor joists and refloored, and it looks great also had them do water control and these guys don't mess around, they did a professional job and took care in doing it!”

Frequently asked

Kennesaw basement waterproofing FAQ.

Because of how fast the water arrives. On slopes where the red clay subsoil is near the surface, a heavy downpour runs off before it can soak in, and the runoff piles up against the lowest buried wall. A slow rain has time to soak in more evenly. Grading and downspout work outside often help most in that case.
