A Drier Home Starts with Waterproofing Services in Sandy Springs, GA

The split-levels and ranches built along Roswell Road and through the Riverside area in the 1950s and 60s were almost all built on vented crawlspaces, and those vents let in as much water as air during storm season. Our process installs a drainage channel network across the crawlspace floor to move water to a sump pit, covers the bare ground with a vapor barrier to stop soil moisture from evaporating into the space, and drops in a pump that switches on automatically when water accumulates. For a home of this era, no other upgrade comes close to the impact on indoor air quality.

If the crawlspace is chronically humid but not flooding, closing it off from the outside environment is the fix. We seal every vent penetration, line the walls and floor with a reinforced polyethylene liner rated for ground contact, and install a dehumidifier with enough capacity to handle the moisture load that the Chattahoochee corridor pushes into the space during summer. What changes for the homeowner: the stale musty smell is gone, the HVAC runs less, and the air on the main floor is noticeably cleaner.

The larger homes near City Springs, North Springs, and High Point tend to have full or partial basements, and in this market a wet one is a dealbreaker at resale. We install a perimeter drainage system around the inside of the basement walls, a sump basin with a pump rated for the space, and a wall liner that channels seepage down into the drain. Whether the lower level is a home office, finished living space, or just storage, the system keeps it dry through the kind of storms that drop several inches in an afternoon.

The wooded, rolling lots that make Sandy Springs desirable also tend to direct stormwater right at the foundation. Tree roots have often shifted the original grading over the years, and downspouts discharge too close to the walls. We install a combination of subsurface trench drains, surface grates at the low points, and downspout extensions that move roof water well past the foundation. Where the slope has settled against the house, we regrade to redirect it.

Pump capacity is not a guess. We figure out the right gallon-per-minute rating based on the crawlspace or basement size, how high the local water table sits, and the runoff volume your particular lot generates. Near the Chattahoochee River corridor, groundwater levels run higher than average, and a pump that is undersized for the property will fall behind during a stalled storm. We install one that will not.
