El Cid’s 1920s–1930s seawalls were built from minimally reinforced concrete designed for a 40–50 year service life — they’re now 80–100 years old. Chloride penetration has reached the embedded rebar, and rust expansion is cracking the concrete from the inside out. Polyurethane injection and cap sealing can halt further spalling on walls with structural integrity remaining, extending life by 15–25 years without the cost of full replacement.

Seawall repair on Lake Worth Lagoon requires Palm Beach County Building Division permits, a South Florida Water Management District Environmental Resource Permit (ERP), and Florida DEP Southeast District review. Work in the navigable channel also requires Army Corps of Engineers Section 10 authorization. We manage all permitting — typically 3–6 weeks for the full permit package.

The C-51 Canal discharges Lake Okeechobee drainage into the lagoon at Palm Beach Lakes Boulevard, creating a seasonal freshwater pulse that lowers salinity in the northern Intracoastal near downtown West Palm Beach. This salinity cycling stresses older concrete panels differently than steady-salinity saltwater — concrete designed for consistent-salt conditions develops micro-fractures under the cyclic expansion and contraction.

Yes. The Flagler Drive and El Cid waterfront now experience king tide overtopping 4–6 times per year — up from near-zero events 30 years ago. Repeated overtopping saturates backfill soil, scours the seawall base, and drives additional salt into existing cracks. WPB properties on Lake Worth Lagoon should include king tide post-event inspection in their annual maintenance schedule.
