Fort Myers Flood Protection — Engineered for Southwest Florida
County: Lee • Surge profile: Caloosahatchee riverine + wind-push • Focus: Perimeter for multi-openings; slab uplift mitigation
What fails here — and how we prevent it
- Threshold leaks (6–12″ outside): we enforce ≤3 mm sill flatness, side-post shims, compression seal verification, and a timed hose test with seepage logged (L/min).
- Garage slab uplift: slab/joint assessment, crack/joint injection as needed, perimeter barrier option to keep surge off the slab, and pump-throughput planning.
- Overtopping risk: height audit with ≥1′ margin; if expected surge exceeds doorway system, we specify perimeter systems.
- Salt-air corrosion: marine-grade alloys/fasteners and a maintenance schedule appropriate for coastal exposure.
Perimeter vs. Doorway — Decision Guide
Doorway/Opening Systems
Best for 1–2 recessed openings, lower surge. Requires slab QA and pump sizing.
Perimeter Systems
Best when multiple openings or surge height is high; keeps water off the slab. Requires pump-out for rainfall inside the ring.
Frequently Asked Questions
Do doorway barriers cause slab failure?
Barriers focus load at openings; uplift is mitigated via slab assessment, joint sealing, and perimeter options where appropriate.
How flat must my threshold be?
≤3 mm variance across the span, verified by hose test and seepage log.
Do I need pumps?
Yes—sized by opening area and head, with backup power and check valves.
