Basement Waterproofing

Florida basements flood. Act before yours does.

A Florida basement isn't like a basement anywhere else. The ground stays saturated for six months of the year. Skip the waterproofing and water intrusion is a matter of when, not if.

Why Florida basements flood

water

High water table year-round

Central Florida's water table sits just a few feet below the surface before rainy season even starts. A basement sits directly in that zone. When the water table rises, it pushes against every inch of your foundation walls and floor at once.

Six months of rainy season

Florida's rainy season runs May through October, which accounts for 60 to 70% of annual rainfall. The ground saturates fast and stays wet. A basement without a waterproofing system is under sustained hydrostatic pressure for half the year.

Mold within 48 hours

Florida's heat and humidity speed up mold growth. Once water enters a basement through a crack, a mortar joint, or the floor slab, mold can establish within 48 hours. A slow seep that goes undetected for weeks results in extensive colonisation inside your walls, long before it shows in the room.

How we waterproof a Florida basement

No single product solves a Florida basement. Effective waterproofing uses all three recognised methods: Type A barrier coatings, Type B structural crack sealing, and Type C interior drainage. Hydrostatic pressure, vapor transmission, and existing wall cracks all need addressing at once.

  1. 1

    Full assessment and moisture mapping

    We inspect every wall, the floor slab, and all penetrations. That means mapping active entry points, measuring moisture levels, and checking for mold already present behind the walls. The results tell us which combination of Type A, B, and C methods your basement needs, and whether mold remediation should come first.

  2. 2

    Crack injection and wall sealing (Type B)

    Existing cracks and failed mortar joints are injected with polyurethane or epoxy foam to seal the entry point structurally. Wall surfaces get a penetrating waterproof coating to block moisture vapor through the block or concrete. This brings the installation to Florida Building Code R406 standards.

  3. 3

    Interior drainage channel (Type C)

    A drainage channel goes in along the perimeter wall-floor joint, which is where most Florida basements take on water. It collects seepage and routes it to the sump pit before it pools on the floor or wicks into the walls.

  4. 4

    Sump pump with battery backup

    Collected water routes to a sump pit and is pumped out automatically. In Florida's rainy season, a sump pump runs often. We install properly sized units with battery backup so the system keeps running through storm-related power outages, which is when you need it.

We stop the intrusion and address any damage the water has caused.

Many waterproofing contractors can install a drainage system. But few are licensed and equipped to address any mold that may have already developed. As well as address any restoration of compromised materials, including drywall and flooring. Why not save yourself the trouble of having to deal with and organize multiple contractors?

Bullfrog does it all. We are licensed mold remediators (#MRSR5565) who also install basement waterproofing systems. If mold is discovered at any step of the process, we deal with it without you having to juggle separate companies. Simplify things with one scope and one warranty.

Common questions

Does Florida have basements?expand_more
Most Florida homes don't have basements because the water table sits close to the surface statewide. In many areas, you hit water just a few feet down. Building below grade requires significant waterproofing from day one. That said, basements do exist in Florida, mainly in older construction and homes built on higher-elevation terrain. When they exist, they're highly susceptible to water intrusion given Florida's rainfall volume and consistently high water table.
What is the building code for waterproofing in Florida?expand_more
Florida Residential Building Code Section R406 requires dampproofing or waterproofing on any concrete or masonry foundation wall that retains earth and encloses a below-grade space. Where hydrostatic pressure is present, as it commonly is throughout Florida, full waterproofing rather than dampproofing is required. Bullfrog installations are built to meet and exceed R406.
What are the three types of basement waterproofing?expand_more
There are three recognised waterproofing approaches. Type A (Barrier) applies a waterproof membrane to the outside of the foundation wall to block water entry. Type B (Structurally Integral) uses crack injection and concrete additives to make the structure itself water-resistant. Type C (Drained) collects water that enters and removes it via interior drainage channels and a sump pump before it can pool or cause damage.
Will insurance pay for basement waterproofing?expand_more
Homeowners insurance generally does not cover basement waterproofing. Most policies exclude gradual water damage and maintenance-related issues, which is how insurers classify a chronic wet basement. If a sudden covered event such as a burst pipe caused the damage, some remediation costs may be reimbursable. Flood insurance (separate from homeowners) may cover damage from a flooding event but typically won't pay for the waterproofing system itself. Bullfrog can assist with documentation and insurer communication where applicable.
Can you fix a wet basement from the inside?expand_more
Yes. Interior (Type C) waterproofing is often the most practical option in Florida, especially when exterior excavation isn't feasible. A drainage channel along the perimeter collects water entering through the walls and floor joint, routes it to a sump pit, and a pump removes it automatically. This doesn't stop water at the wall face, but it manages water before it pools or causes structural damage.

“Our basement had been seeping for years and every contractor we called said they couldn't do much. Bullfrog put in a full drainage system and sump pump. Completely dry through two rainy seasons since.”
