AVS Marine handles the full seawall scope: removal of failing structures, new wall installation, cap pours, deadman/tieback anchoring, weep and filter systems to relieve hydrostatic pressure, and clean backfill and grading. We match the wall system to your site — water depth, soil, exposure, and how the shoreline is used.
Repair vs. replacement
Not every wall needs to come out. Cracked caps, leaning panels, voids behind the wall, and failed tiebacks can often be repaired or reinforced. When a wall is past its service life, we plan a clean replacement that protects your upland and meets current code.
Built for Florida conditions
Saltwater, sun, wakes, and surge are hard on shoreline structures. We specify corrosion-resistant materials and proven detailing so the wall holds up — and we coordinate permitting with the county, state, and Army Corps where required.

Frequently asked questions
Do you repair existing seawalls or only build new ones?
Both. We handle new seawall construction, full replacement, and repair work such as cap repair, panel replacement, tieback/anchor repair, and backfill stabilization.
What seawall materials do you use?
Vinyl sheet pile, concrete, and composite systems are the most common. The right choice depends on water depth, soil, exposure, and budget — we walk you through the trade-offs on site.
How long does a seawall last in Florida?
A properly engineered and maintained seawall can serve for decades. Service life depends on materials, water chemistry, drainage behind the wall, and how exposed the shoreline is.
Do I need a permit for seawall work?
Most seawall work in Florida requires permits from the county and, depending on the waterway, the state (FDEP) and/or the U.S. Army Corps of Engineers. We handle that process for you.
