The seawall cap serves the function of tying and securing all the panels into their installed positions. In other words, the seawall cap holds everything together. Most seawall caps are made from poured concrete reinforced with steel. The great thing about concrete is that it never lies. Concrete always displays a stress reaction to unstable soil.
Once a seawall begins to experience movement related to soil instability caused by soil migration and void formation, the seawall cap experiences tremendous lateral stress. This stress is caused by the build-up of hydrostatic pressure and water-saturated soil (typical soil grade mass) on the landward side of the seawall. Also, the seawall berm (the soil mass surrounding the bottom of the seawall) has typically been compromised at this point and has become unstable as well.
Seawall Repair Network contractors employ high-strength epoxy and concrete repair materials to repair cracks in seawall caps. This process restores strength and integrity to the structure. The Seawall Repair Network’s proprietary materials, equipment, and repair processes remedy this kind of damage and other seawall issues.
