The primary causes are Grand Strand ICW tidal cycling with Atlantic coastal storm surge exposure on the narrow barrier island. Combined with Horry County sandy Grand Strand coastal soils with narrow barrier island overwash risk, these forces accelerate void formation, panel cracking, and joint separation. Surfside Beach's narrow barrier island profile increases storm overwash risk on ICW seawalls — backfill saturation during Nor'easters and tropical storms accelerates void formation.

Most Surfside Beach seawall repairs using polyurethane injection or helical tiebacks are completed in 1–2 days. We schedule work around low tide windows for maximum access and accuracy.

Structural repairs including tieback installation and cap replacement require Horry County permits and may require DEP or Army Corps review for waterfront properties adjacent to Intracoastal Waterway and the Atlantic Ocean. Polyurethane injection and maintenance repairs generally do not require permits. We handle all permitting coordination for major projects.

We recommend annual inspections for seawalls older than 20 years, plus inspection after every named storm event. Surfside Beach's narrow barrier island profile increases storm overwash risk on ICW seawalls — backfill saturation during Nor'easters and tropical storms accelerates void formation. Early detection of voids and micro-cracks costs far less to address than waiting for visible structural failure.
