Foundation Waterproofing Anna Maria Island
Engineered waterproofing for Anna Maria Island beach homes, elevated waterfront estates and island businesses, where the water table sits just below your feet and rises with every tide. Backed by a lifetime transferable warranty.

Waterproofing Built for Island Living
On a barrier island, groundwater is never more than a few feet down, and it is salty, tidal and pushed higher by every storm. Older island cottages sit on slabs at grade, and newer elevated homes still have elevator pits, garages, pool equipment rooms and enclosures at ground level. We waterproof all of them.
We work in all three island cities, Anna Maria, Holmes Beach and Bradenton Beach, and we coordinate our work with each city’s building department and flood rules.
Every system we install carries a Lifetime Transferable Warranty. That matters at resale, because known water problems have to be disclosed when a Florida home is sold. Warranty transfer details.
Why Island Homes Need Engineered Waterproofing
Tidal Groundwater
The water table under the island rises and falls with the Gulf and the bay, so pressure on slabs and pits changes twice a day.
Elevator Pits & Ground Levels
Elevated waterfront homes still have elevator pits, garages, pool equipment rooms and ground-level enclosures that sit in or near the water table.
Salt Exposure
Salty groundwater and air attack concrete and steel, which makes keeping water out of the structure even more important.
Older Island Cottages
Many original Florida cottages sit on slabs close to grade, built long before modern moisture control.
2024 Storm Season
Hurricane Helene pushed storm surge across the Gulf barrier islands in September 2024, and Hurricane Milton made landfall near Siesta Key two weeks later, a reminder of how fast water rises here.
Proactive Waterproofing
Perimeter collection, sump discharge and wall waterproofing, installed before damage spreads, save owners the cost of floors, finishes and mold remediation later.
Gulf-front homes and canal-front estates
How Water Gets In on Anna Maria Island
The island is a narrow strip of sand between the Gulf of Mexico and Anna Maria Sound. Rain soaks straight in, and the fresh water floats on salt water just a few feet down. When the tide rises or a storm pushes water in, that whole lens rises with it.
Elevator pits and ground-level slabs sit right in that zone. Water comes through the pit floor, wall joints and conduit penetrations, and through cracked or unsealed slabs in garages and enclosures.
We design for the tide, not just the rain: sealed pits, collection and sump relief where the site allows, and waterproofing rated for constant moisture and salt.
FEMA maps all of Anna Maria Island in high-risk flood zones, with VE zones along the Gulf and AE zones on the bay and canal side. You can look up any address on FEMA’s Flood Map Service Center. Keep in mind that a flood zone shows surface flood risk; groundwater pushing up under a slab happens inside and outside the mapped zones.
Protecting Island Property & Closing Florida’s Code Gap
The Florida Building Code’s waterproofing provisions are written mainly for below-grade walls such as basements. When a below-grade structure is proposed, building officials generally look to those provisions and the International Building Code. They say very little about the condition most Anna Maria Island homes are in: a slab on grade sitting close to the seasonal high water table. A home can pass every inspection and still take on water from below.
Our engineered systems fill that gap, and every installation carries a Lifetime Transferable Warranty, documented proof for the next buyer that the water problem was solved correctly.

Our Anna Maria Island Waterproofing Systems
Perimeter Collection
Collection lines along the footing that intercept groundwater before it reaches the slab.
French DrainsSlab Moisture Control
For wet grout lines, cupping wood floors and moisture rising through the slab.
Floor CuppingSite and Stormwater Drainage
Runoff captured across drives, pool decks, courtyards and garages and carried to a proper discharge point.
Drainage ProblemsBelow-Grade Waterproofing
Lower levels, basements and below-grade rooms, with interior channels and sump discharge.
Basement WaterproofingRoof Water Management
Seamless gutters tied into smooth PVC drain lines, so roof water never reaches the foundation.
Gutters and DrainageCommercial Water Intrusion
For owners and developers of hospitals, hotels, schools, offices and retail: rear doors, shared walls and slabs, scoped to keep the building open.

Anna Maria Island Waterproofing FAQ
Can you waterproof an elevator pit on Anna Maria Island?
Yes. Elevator pits on the island sit in tidal groundwater. We seal the pit floor, walls and penetrations and add relief where the site allows, so the pit stays dry and the elevator stays in service.
My home is elevated. Do I still need waterproofing?
Often, yes. Garages, storage enclosures, pool equipment rooms, elevator pits and pool decks all sit at ground level, where tidal groundwater and storm water reach them.
Do you work in Holmes Beach and Bradenton Beach?
Yes. We work in all three island cities, Anna Maria, Holmes Beach and Bradenton Beach, and confirm permit requirements with each city before work starts.
How much does waterproofing cost on Anna Maria Island?
It depends on the structure. Elevator pit and enclosure work is usually smaller in scope, while a full slab and perimeter system on an at-grade home typically runs $20,000 to $40,000.
Do you offer free inspections on the island?
Yes. Call 813-614-4830 or send the form below. We find where the water is coming from and give you a written plan.
