Seawall Repair for Key Biscayne 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 Key Biscayne 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.
