Seawall Repair for Miami Beach waterfront properties
Langley Coastal has a variety of tried and true methods for repairing and restoring all types of seawalls. First, we identify what issues your Miami Beach seawall is having, with thorough inspections that include underwater photos and videos of its condition and potential repair methods.
Then we recommend the repair: simple hydraulic cement crack repairs, major repairs with new forms and rebar, or high-density polyurethane foam injection. To stop water and sediment flowing through fractures or voids in the footer, we use NCFI's Terra-Lok™ foam.
Making the necessary repairs as quickly as possible can reduce the need for heavily intrusive excavating in the future and save money. More about seawall repair.
Seawall Repair in Miami Beach: what's specific here
The rule in Miami Beach: City Code Sec. 54-62 (Ord. 2021-4393, amended by Ord. 2025-4754 on 2025-07-16): all new seawalls and seawalls undergoing substantial improvement must reach 5.7 ft NAVD88; less-than-substantial repairs may stay at 4.0 ft NAVD88 only if designed for a future 5.7 ft. The city's FAQ defines a substantial repair as $300 or more per linear foot. [mbrisingabove.com] Which means a repair that keeps the existing wall is often the practical route, and a rebuild has to meet the new elevation.
King tides hit September-November and can run more than 12 inches above the year's average high tide; 2026 peaks are Oct 10 and Oct 26-27, and the city deploys temporary pump stations in the lowest neighborhoods [mbrisingabove.com] That is the kind of water pressure that opens cracks and washes soil out from behind a Miami Beach seawall.
Permits: City of Miami Beach Building Department + Miami-Dade DERM Coastal Resources Section (Class I) + FDEP / USACE as applicable. The city FAQ lists the building-permit package (site plan, structural design, elevation certification) and states DERM Coastal Resources approval is required for seawall construction, with FDEP for state-owned bottom and a USACE Section 404 permit for any dredge or fill.

Does the Miami Beach seawall rule apply to a repair?

The city's FAQ defines a substantial repair as $300 or more per linear foot. Whether a given repair triggers the standard depends on the extent of the work; the inspection tells us which route fits.

Why do Miami Beach seawalls fail?
About 55 miles of seawall ring the city; roughly 5 miles are public and 91% is private, so private walls are the first line of defense on the bay side and canals Water and sediment moving through cracks or voids in the footer wash out the soil behind the wall; foam injection seals those paths.
