Seawall Structural Concerns
Seawall repairs are a common concern faced by coastal and shoreline residences. A waterfront Seawall is constantly impacted and stressed by water flow via tidal flux and seasonal storms. No matter how well engineered, eventually all seawalls will face erosion and weathering and thus all Seawalls will require repairs at some point.
Seawalls can be an engineering marvels if constructed correctly. Frequently, however, their construction is less than satisfactory and after only a few years they will begin to show signs of stress and begin eroding soil under and through cracks in your Seawall. This can pose a dangerous threat to people near or adjacent to the walls after erosion begins, due to unstable earth and concrete after voiding of the soils. Often, these voids are covered by vegetation and are hidden from casual view.
Seawalls in need of repair can also pose a huge threat to nearby buildings and structures once the erosion cycle starts. Once this process starts, it’s a constant and usually losing battle to repair the erosion areas such as cracks and holes and to continue filling eroded soil voids with new soil to retain proper soil compaction to support these structures.
Look For Seawall Erosion:
Warning Signs Indicating Need of Seawall Repair:
EROSION SIGNS – What To Look For:
Persistent rain, waves, tidal action, poor irrigation and run-off can amount to quickly compounding and expensive to repair sea wall soil erosion or “Voids” below ground and behind your Seawall.
ANCHOR FAILURE SIGNS – What To Look For:
Prolonged exposure to saltwater where corrosion has deteriorated the Anchor Rod and fasteners to a point where excesses in weight or loading from behind the wall creates possible failures of the Seawall.
CAP FAILURE SIGNS – What To Look For:
Prolonged exposure to saltwater where corrosion has caused the reinforcing steel in the Seawall Cap to corrode and expand causing cracks to develop. As the steel continues to corrode and expand, portions of the Cap will break off, thus weakening the Cap, leading to failure of the Seawall.
SHEET PILE FAILURE SIGNS: What To Look For:
Loss of berm in front of the Seawall causing the toe of the Seawall wall to move outward at the bottom. Excess loading from behind causing horizontal cracks to develop in the Seawall sheet piles, exposing the reinforcing steel in the sheet piles to saltwater. Prolonged exposure to the harsh elements weakens the sheet piles, which will lead to failure of the Seawall.
