Seawall Repair

Langley Coastal has a variety of tried and true methods for repairing and restoring all types of seawalls.

First, we need to identify what issues your seawall is having. We provide thorough seawall inspections including underwater photos and videos showcasing the condition of your seawall as well as potential repair methods.

Once we have identified any issues you are having we can suggest necessary repair methods. We offer simple hydraulic cement crack repairs, major repairs with new forms and rebar, and high density polyurethane foam injection. Making the necessary repairs as quickly as possible can reduce the need for heavily intrusive excavating in the future and save money.

Some signs you may see that indicate your seawall is in need of repairs are:

Cracks or breaks in sections of your seawall

Signs of significant wear and degradation

A sag or slope in your seawall

Loss of soil or holes formed behind your seawall

Rust stains or exposed rebar

Exposed tie backs or supports

Anything protruding that may cause injury

High Density Foam Injection

To combat water and sediment flowing through fractures in your seawall or voids in your footer, LCC uses NCFI's Terra-Lok™ 24-120 foam to create an effective water cutoff. The polyurethane is injected directly into the existing medium behind your wall, infiltrating fractures and voids within the dirt, sand, and rock. Once injected, the foam expands to fill these crevices, forming a robust, watertight seal that effectively stops underground water intrusion. This precise sealing process ensures that even the smallest fractures in the wall are addressed, preventing any pathways for water seepage, reinforcing the structural integrity of the bulkhead itself, and preventing erosion.


The Terra-Lok™ polyurethane's rapid reaction time is critical in achieving immediate water stoppage, allowing the seal to form quickly upon contact with moisture in the material. As the foam expands, it adheres to both porous and non-porous surfaces within the rock formation, creating a continuous barrier that adapts to the irregular contours of the bulkhead. This adaptability ensures that the seal was comprehensive and long-lasting, even in areas with significant geological variation.
