Seawall Repair for Longboat Key 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 Longboat Key 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.

The rule in Longboat Key: Town Commission voted 7-0 on April 1, 2024 to raise the maximum allowable seawall height from 4.5 ft to 6 ft (Chapter 151), citing 6 inches of sea-level rise in 20 years and walls being overtopped; by March 2025 the town had issued 27 permits to raise seawall heights.
