What this video covers
Smart Seawall Technology (SST), a company with offices in Port Orange, St. Augustine, and St. Lucicane, demonstrates its modular seawall system designed to address corrosion and sea-level rise.0:46 The system uses HDPE outer shells filled with 6,000 psi concrete and fiberglass rebar — no steel or galvanized components — eliminating the corrosion failures common in brackish and saltwater environments.5:58 Panels come in two-foot sections that snap together, allowing the wall height to be raised incrementally as sea levels rise, something traditional monolithic seawalls cannot accommodate.1:33 The cap profile is curved on both faces rather than flat, so incoming waves deflect back seaward instead of shooting 12–15 feet into the air and dropping onto the landward side; that wave-return scour is the primary mechanism by which conventional seawalls loosen soil and eventually fail.3:44 Installation uses a water-jet process: a pipe jets down to full depth — typically 14–16 feet — while simultaneously vacuuming sand to create the cavity, then concrete is pumped through a bottom-feed pipe and the pipe is withdrawn without vibration, which would otherwise separate cement paste from aggregate.5:29
