The primary causes are Longboat Pass tidal inlet creating current acceleration along the north Longboat Key ICW waterfront. Combined with Manatee-Sarasota County barrier island sandy soils with high-value resort residential seawalls, these forces accelerate void formation, panel cracking, and joint separation. Longboat Pass is an active tidal inlet that creates current acceleration along the north end of Longboat Key — seawalls near the pass experience significantly above-average tidal scour.

Most Longboat Key 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 Manatee County permits and may require DEP or Army Corps review for waterfront properties adjacent to Sarasota Bay 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. Longboat Pass is an active tidal inlet that creates current acceleration along the north end of Longboat Key — seawalls near the pass experience significantly above-average tidal scour. Early detection of voids and micro-cracks costs far less to address than waiting for visible structural failure.
