AnswerDeckmasters Marine designs, FDEP-permits, and installs vinyl sheet-pile seawalls with structural concrete caps for waterfront homes in Vero Beach, John's Island, Windsor, and Orchid Island. One licensed Florida marine contractor (RG291103858) handles every phase — survey through final inspection.

AnswerCompleted and in-progress vinyl sheet-pile seawall projects across Vero Beach, Indian River Shores, Orchid Island, Windsor, and Sebastian. Each shoreline gets the same engineering discipline — FDEP permit pack, stamped structural section, 5,000-psi cap, 316 stainless tieback — adapted to its specific tide, surge, and substrate.
Drone view of a finished vinyl sheet-pile seawall along a private waterfront estate. Concrete cap, stainless cable rail, manicured upland — the long view of what twenty-one years of engineering looks like.
AnswerA 25-year-design-life vinyl sheet-pile wall capped in 5,000-psi sulfate-resistant concrete, tied back to deadman anchors on every fourth pile with 316 stainless, fully FDEP-permitted, ARB-coordinated where required, and built by a self-mobilized crew — no subcontractor hand-offs.
8″ ESP-series profile, UV-stabilized PVC, structurally rated 64 kip-ft/ft, salt-immune. The wall face that doesn't corrode in the Indian River Lagoon's brackish chemistry.
5,000 psi, Type II SR (sulfate-resistant) cement, FRP rebar at 6″ O.C., no chloride attack. The load path that lets the wall outlast the fasteners.
¾″ 316 stainless rods at 22° batter, anchored to 4×4 PT timber deadmen at 4.5 m setback — every fourth pile. Highest-grade marine fastener.
Self-mobilized barge, crane, vibratory hammer; no rented sub, no schedule slip. Driven to engineered refusal, typically 22–30 ft into the lagoon bottom.
FDEP Environmental Resource Permit, Sovereign Submerged Lands, Indian River County building permit, community ARB — all filed in-house as part of every contract.
Keith Hennessy (RG291103858) is the qualifier and the field foreman. One licensed marine contractor from survey through final inspection.
AnswerSurvey and engineering, permitting, mobilization and pile-drive, cap pour and tieback, backfill and finish — five sequential phases, typically 90 to 180 days end-to-end, with the longest single phase being FDEP permit review (45 to 90 days).
01Survey & engineeringLicensed surveyor establishes property line, MHWL, and existing-wall condition; structural engineer designs against hydrostatic head, soil surcharge, FEMA storm-surge cases, and 25-year design life. 14–28 days | 02PermittingFDEP Environmental Resource Permit, Sovereign Submerged Lands, Indian River County building permit, and community ARB submission filed in parallel where possible. 45–90 days | 03Mobilization & pile-driveSelf-mobilized barge, crane, and vibratory hammer; vinyl sheet piles driven to engineered refusal — typically 22 to 30 ft below the lagoon bottom. 5–10 days | 04Cap pour & tiebackFRP rebar cage, formwork, single continuous pour of 5,000-psi sulfate-resistant concrete; 316 stainless tiebacks to deadman anchors every fourth pile. Cap cures 7 days. 7–14 days | 05Backfill & finishClean #57 stone backfilled 3 ft behind the wall for drainage; final grade restored; turf reinstated; punch-list inspection with the homeowner and the county. 3–5 days |
AnswerSalt, brackish water, manatee-grass beds, hurricane surge, the daily tide cycle — every material on this wall is specified against the Indian River Lagoon, not a generic catalog. The vinyl is UV-stabilized. The rebar can't rust. The concrete cap is poured with sulfate-resistant Type II cement.
Sheet pile
Salt-immune, no corrosion, 25+ yr warranty
Cap
Sulfate-resistant for brackish exposure
Reinforcement
Zero corrosion in marine environment
Tieback
Highest-grade marine fastener
Deadman
Lateral load resistance
Backfill
Drainage; prevents hydrostatic build-up
AnswerVinyl sheet-pile seawalls on the Indian River Lagoon run $480 to $920 per linear foot in 2026, depending on wall height, tieback density, cap type, and existing-wall demolition. A binding proposal follows a site visit.
| Wall height | $ / LF (2026) | Notes |
|---|---|---|
| ≤ 4 ft | $480 – $620 | Standard residential lagoon wall |
| 4 – 6 ft | $620 – $760 | Adds tieback density |
| 6 – 8 ft | $760 – $920 | Adds engineering, may require steel I-beam king-piles |
| Existing-wall demo | $40 – $120 /LF | Depends on existing material |
AnswerVinyl sheet pile beats concrete and timber on the Indian River Lagoon for three reasons — it doesn't corrode in brackish water, it installs in days instead of weeks of formwork, and the 25-year manufacturer warranty is backed by an active product line. Concrete is reserved for vertical heights above 8 ft.
| Material | Design life | Install / 100 LF | $ / LF | Best for |
|---|---|---|---|---|
| Vinyl sheet pile + concrete cap | 25 yr | 7–10 days / 100 LF | $480 – $920 | Residential lagoon, ≤ 8 ft |
| Cast-in-place concrete | 40 yr | 21–28 days / 100 LF | $900 – $1,500 | Commercial, ≥ 8 ft height |
| Treated timber | 15 yr | 5–8 days / 100 LF | $320 – $520 | Temporary / budget repairs only |
AnswerDeckmasters has completed seawall projects in Windsor, John's Island, Orchid Island, Quail Valley, and Riomar since 2005; license RG291103858 is in good standing with the Florida Department of Business and Professional Regulation; insurance includes USL&H and Jones Act coverage.

AnswerThe five questions homeowners ask in the first phone call — FDEP permits, design life, manatee season, ARB matching with neighbors, and what happens to the existing wall during the build. Long-form answers below; phone-call answers stay the same.
AnswerSite visits with Keith Hennessy (RG291103858) start every seawall project. Bring the survey if you have one, the existing wall's install date if you know it, and the community ARB packet if you live in a gated community. Most estimates land within ten business days of the walk.
