The primary causes are Little River Inlet creating ICW current acceleration in the North Myrtle Beach waterfront section. Combined with Horry County sandy coastal soils with active vacation rental waterfront and ICW boat traffic, these forces accelerate void formation, panel cracking, and joint separation. North Myrtle Beach's proximity to Little River Inlet creates tidal current acceleration on the ICW — seawalls near the inlet require more frequent inspection than central Myrtle Beach ICW walls.

Most North Myrtle 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 Little River Inlet. 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. North Myrtle Beach's proximity to Little River Inlet creates tidal current acceleration on the ICW — seawalls near the inlet require more frequent inspection than central Myrtle Beach ICW walls. Early detection of voids and micro-cracks costs far less to address than waiting for visible structural failure.
