South Florida's saltwater environment degrades seawalls faster than anywhere in the country. A failing seawall can cost $500–$1,500 per linear foot to replace. Annual drone inspection catches problems at the repair stage — not the replacement stage.

Many seawall failures are invisible from the dock or seawall cap. Aerial oblique angles and AI analysis reveal problems years before collapse.
Longitudinal cracks in the concrete cap indicate soil settlement or rebar corrosion beneath. Caught early, a patch repair can extend seawall life 10+ years.
Blocked weep holes trap hydrostatic pressure behind the wall, the leading cause of catastrophic panel failure. Aerial imaging confirms whether weeps are clear.
Tidal scour removes soil from the landward base of the wall. Low-angle aerial flight spots soil voids and subsidence along the seawall toe before settling progresses.
Concrete panel or sheet pile separation allows direct backfill erosion. Drone surveys run along the full seawall face identifying even hairline gaps between panels.
Rust streaks indicate corroding tie-back anchors — a critical structural component. Rust mapping provides the contractor exact replacement zones.
Hurricane surge and wave action can laterally displace panels millimeters — enough to accelerate failure. Immediate post-storm survey documents displacement for insurance.
Annual seawall assessments for reserve planning. Our reports include a linear-foot condition rating and estimated repair timeline.
Pre-purchase seawall documentation for lenders and buyers. Know what you're buying before closing.
Pre-bid site survey and post-repair documentation. Give clients an aerial record of completed work and current condition.
