Seawall Repair for Miami 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 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: what's specific here
The rule in Miami: City Code Ch. 29 Art. III (Bulkheads, Seawalls, Living Shorelines) as amended by the 2020 ordinance (File 7338): new and reconstructed seawalls, bulkheads and living shorelines in tidally influenced areas must be built to a minimum 6 ft NAVD88 and designed so they can be raised to 8 ft NAVD88; properties fronting the Miami River follow Sec. 54-46 (4.0 ft NAVD88, raisable at least 2 ft). [miami.gov] 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 occur September-November, each peak lasting about 3 hours, and cause sunny-day street flooding near waterways and in low inland pockets; the city takes reports at 311 [miami.gov] That is the kind of water pressure that opens cracks and washes soil out from behind a Miami seawall.

Does the Miami seawall rule apply to a repair?
City Code Ch. 29 Art. III (Bulkheads, Seawalls, Living Shorelines) as amended by the 2020 ordinance (File 7338): new and reconstructed seawalls, bulkheads and living shorelines in tidally influenced areas must be built to a minimum 6 ft NAVD88 and designed so they can be raised to 8 ft NAVD88; properties fronting the Miami River follow Sec. 54-46 (4.0 ft NAVD88, raisable at least 2 ft). Whether a given repair triggers the standard depends on the extent of the work; the inspection tells us which route fits. [source]

Why do Miami seawalls fail?
Hurricane Irma (2017) pushed 3-5 ft of inundation along the bay shoreline from Homestead to downtown/Brickell, 1-2 blocks inland, with isolated spots over 6 ft in Coconut Grove and Brickell; 2-3 ft north of downtown Water and sediment moving through cracks or voids in the footer wash out the soil behind the wall; foam injection seals those paths.
