The primary causes are North Edisto River tidal estuary with full Charleston area 5-6 foot tidal amplitude and Bohicket Creek tributary flow. Combined with Charleston County private resort island soils with active North Edisto River tidal current scour effects, these forces accelerate void formation, panel cracking, and joint separation. Bohicket Creek and the North Edisto River create multi-directional tidal forcing on Seabrook Island seawalls — panels here experience tidal stress from multiple angles simultaneously.

Most Seabrook Island 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 Charleston County permits and may require DEP or Army Corps review for waterfront properties adjacent to North Edisto River and the Intracoastal Waterway. 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. Bohicket Creek and the North Edisto River create multi-directional tidal forcing on Seabrook Island seawalls — panels here experience tidal stress from multiple angles simultaneously. Early detection of voids and micro-cracks costs far less to address than waiting for visible structural failure.
