Basement Waterproofing Company in Louisville, KY

Aqua Lock is family-owned by Jay and Becky Kraft, headquartered at 10470 Bluegrass Parkway in Jeffersontown, just inside the I-264 loop and five miles from downtown Louisville. We have been working in Louisville basements, crawl spaces, and foundations since 2006. Twenty years, 10,000-plus homes repaired across Kentucky, and a Lifetime Transferable Warranty on every waterproofing job.

Why Louisville Homes Need a Foundation and Waterproofing Specialist

Louisville homes face a specific set of conditions that drive foundation, basement, and crawl space work:

Exterior foundation waterproofing process showing black moisture barrier and trench excavation.
  • Ohio River Valley humidity that pushes basement and crawl space moisture levels up most of the year. Louisville sees some of the highest summer humidity east of the Mississippi.
  • Clay-heavy soils that expand and contract with each rainy season, putting lateral pressure on foundation walls. Bowing walls and stair-step cracks are the visible result.
  • Freeze-thaw cycles. Louisville averages 10 to 20 freeze-thaw cycles per winter, more aggressive than further south. Each cycle stresses mortar joints and small foundation cracks.
  • Limestone karst geology under parts of Jefferson County. The drainage complexity that comes with karst affects how water moves through the soil and into basements.
  • Pre-1970 housing stock in older Louisville neighborhoods (Highlands, Cherokee Triangle, Crescent Hill, Germantown). Limestone-block and poured-block foundations behave very differently from the newer poured-concrete construction common in East End and South End developments.

Every Aqua Lock inspection starts with what your house is actually sitting on and what season is ahead.

What Homeowners Are Saying

How a Louisville Job Actually Goes

The process is the same whether the job is a single crack repair or a full waterproofing system:

Free in-home inspection. A trained Aqua Lock inspector walks your basement or crawl space with you. 30 to 45 minutes, no obligation, no hard sell.

Written scope and price before you decide anything. The inspector explains what is happening, why, and what your options are.

Installation typically 1 to 4 weeks out. A foreman is on the job from start to finish. Frannie Combs, our Production Manager, stops in. Jay does QC on active jobs.

Frequently Asked Questions

Most inspections are scheduled within 24 to 48 hours of your call.

Yes. We work with homeowners, property managers, realtors, structural engineers, and commercial property owners across the Louisville metro.

Both are common answers, and the right one depends on where the water is coming in. Surface water from grading or downspouts is a different problem from hydrostatic pressure pushing water through the slab or wall joints. A free inspection will tell you which one is happening at your house.

Hairline cracks under 1/8 inch wide are typical in any home and usually do not need repair. Stair-step cracks through mortar joints, widening cracks, or cracks accompanied by sticking doors and sloping floors are signs of foundation movement and should be inspected.

Usually not. Most policies cover sudden water damage (such as a burst pipe) but exclude long-term water intrusion from groundwater or hydrostatic pressure. Waterproofing is generally treated as preventive maintenance. Check your specific policy.
