Concrete for the Hammock and Hammock Dunes — built for salt spray, coquina and storm surge
The barrier island between Marineland and Beverly Beach is the hardest place in Flagler County to make concrete last. Mix design, steel cover, elevation and sealing are what do it, and we build all four in.
The Hammock is the eleven miles of A1A barrier island north of Palm Coast's bridge — the gated oceanfront villages of Hammock Dunes and Hammock Beach with their Fazio courses, Ocean Hammock, Sea Colony, Island Estates on the Intracoastal side, the old-Florida lots of Marineland Acres and Painters Hill, Bings Landing and Washington Oaks. It's unincorporated Flagler County, not the city, so permits come from the county's building department in Bunnell. And it's the one part of our territory where concrete has to be engineered for the environment: salt spray year-round that rusts reinforcing steel from the inside and spalls the surface; VE and AE flood zones that dictate how high a floor sits; coquina rock a foot or two down on some lots; and a storm every few years — Matthew in 2016, Ian and Nicole in 2022 that flattened the dunes along all 18 miles of the county's shoreline, Milton in October 2024 that the county's 11.4-mile emergency dune project held back.
So on the island we pour differently. A lower water-to-cement ratio for a denser slab that salt penetrates more slowly; reinforcing steel set with extra cover so chloride takes years longer to reach it, and epoxy-coated where the engineer calls for it; a penetrating sealer rated for marine exposure, re-applied on a shorter schedule; stem-wall foundations that put an addition's floor above base flood elevation; and coquina-look stamped finishes and shell-toned colors for the driveways and pool decks that have to look like they belong on A1A. The gated communities have architectural committees, and we prepare the submittal.
What we do in The Hammock & Hammock Dunes
Salt-rated mix & steel cover
Denser concrete, more cover over the reinforcing, epoxy-coated steel where specified — so the driveway isn't spalling from the inside in ten years.
Flood-zone foundations
Stem walls and raised slabs for additions and garages in the VE and AE zones, to the engineer's drawing and the county's inspection.
Coquina & shell finishes
Stamped and textured finishes in coquina and shell tones for driveways, walks and pool decks that fit the island.
Pool decks by the ocean
Light-colored, salt-sealed cool-deck and knockdown surfaces, coping joints sealed, decks lifted where the backfill settled.
Storm repairs
Washed-out aprons, undermined slabs and cracked decks after surge and rain events, with the drainage fixed.

Questions from The Hammock & Hammock Dunes homeowners
Why does concrete spall so much on the island?
Salt. Spray and humidity carry chloride into the slab, it reaches the reinforcing steel, the steel rusts and expands, and the concrete above it pops off — that's spalling, and it starts inside where you can't see it. A denser mix, more cover over the steel, and a marine-rated sealer slow it down by years; a driveway poured like it's in Bunnell doesn't stand a chance.
Who issues permits on the Hammock?
Flagler County, not Palm Coast — the island north of the bridge is unincorporated. Driveways that touch the county road right-of-way, structural slabs and anything in a flood zone go through the county's building department in Bunnell, and we handle it. The gated communities add their own architectural review on top.
My lot is in a VE zone. Can I add a garage?
Yes, on a foundation designed for it — typically a stem wall or piers that put the finished floor above base flood elevation with the space below built to let water through. It's engineered work and the county inspects it closely; we build to the drawing.
Can you make a driveway look like coquina?
Yes: a stamped or textured finish in shell and coquina tones, sealed, is the most common decorative request on the island and it suits the old Florida houses in Marineland Acres as well as the new ones in Hammock Beach. Real coquina is a soft stone that doesn't survive as paving; the concrete version does.
What happened to concrete here in the 2022 and 2024 storms?
Nicole in November 2022 breached the dunes and sent surge and sand through oceanfront lots, undermining pool decks and driveways; Ian before it took the dunes down. Milton in October 2024 was mostly rain and erosion — the county's emergency dune project held — and the damage was washed-out aprons and sunken decks. We repaired a lot of both and we build so the next one does less.
