David Watson
Allen and team did a phenomenal job installing an internal drainage and waterproofing system in the basement of a house we are selling for a very fair price. So much so that we got an offer on the house within days of completion after being on the market for two months!

We had a flooding basement in East Atlanta for years and years. I wish I'd called Allen sooner! I'm in awe of how efficient, effective, and affordable it ended up being!

Frequently Asked Questions About a Waterproofing Service

An Alpharetta, GA, homeowner should investigate recurring musty odors, efflorescence, damp wall edges, peeling coatings, condensation, or small puddles that appear after storms. A&A Waterproofing can identify the moisture pathway early and recommend drainage, sealing, sump pumping, or foundation waterproofing before damage spreads.

Yes. In an Alpharetta, GA, crawl space, encapsulation limits ground vapor while a sump pump removes liquid water collected by drainage beneath or around the liner. A&A Waterproofing can integrate the components so the space is protected from both humidity and active water intrusion.

Regrading is often used when surface runoff flows toward an Alpharetta, GA, house, while a French drain is more useful for intercepting water moving through saturated soil. A&A Waterproofing evaluates slope, low points, soil conditions, and discharge options before recommending one method or a combined drainage plan.

An Alpharetta, GA, foundation wall can move inward when lateral soil pressure increases, sometimes worsened by saturated soil and poor drainage. A&A Waterproofing can assess wall condition and determine whether stabilization should be paired with exterior drainage or waterproofing to reduce ongoing pressure.

If an Alpharetta, GA, sump pump runs constantly after rain, A&A Waterproofing checks inflow volume, float operation, pump capacity, discharge restrictions, check-valve performance, and whether discharged water is cycling back toward the foundation. Persistent operation can signal a system problem or unusually high groundwater load.

Waterproofing Company in Alpharetta GA for Moisture Issues and Foundation Repair

Basement moisture often starts with rainwater collecting where the foundation meets the surrounding soil. Our foundation waterproofing approach addresses those exterior conditions before the water has more opportunities to move indoors. Depending on what we find, our team can excavate to the footing, repair active leaks, apply waterproof membranes and coatings, and improve drainage around the home. Helping water move away from the foundation and adding protection to the exterior wall can reduce recurring seepage and the need for cleanup after every stretch of heavy rain.

A basement that has become known for wet corners, raised storage, or constant humidity may need more than another temporary cleanup. Interior basement waterproofing creates a system for collecting and moving water whether the lower level is finished or still exposed block and concrete. Our work may combine interior drainage, leak repair, moisture control, and sump pump integration depending on the layout and water conditions. Addressing those issues can help homeowners use more of the basement without planning around the next heavy rain. Structural warning signs require a closer look as well. Foundation cracks, wall pressure, and bowing can develop when soil shifts or remains active around the home. We begin with an inspection and then choose repairs that match what we find, including crack injections, carbon fiber reinforcement, structural stitching, and stabilization for walls that are showing signs of inward movement.
