Seawall Construction
for the Florida Keys.
Coral substrate, constant saltwater exposure, and hurricane-level storm surge demand seawalls built to a higher standard. Aqua Pilings designs and constructs vinyl, concrete, and rip-rap seawalls custom engineered for your specific shoreline — from quiet canals in Key Largo to exposed bay-front properties in Marathon.

Every Keys shoreline
is different.
A canal-front property in Key Largo faces different tidal patterns, soil conditions, and exposure levels than a bay-front estate in Marathon or an oceanside property in Key West. There is no single seawall solution that works everywhere — which is why every project we take on starts with a thorough on-site assessment.
Building seawalls in the Keys is more technically demanding than mainland construction. The coral rock substrate requires specific installation methods. Saltwater corrosion eliminates materials that would otherwise perform well in freshwater or low-salinity environments. And the permitting process through Monroe County, FDEP, and in some cases the Army Corps of Engineers requires knowledge and experience to navigate efficiently.
We handle all of it — design, permits, and construction — with the same crew from start to finish. No subcontractors, no handoffs, and no surprises on the bill.
The right system
for your shoreline.
We work with three primary seawall systems, each suited to different site conditions, budgets, and long-term goals. After assessing your property we will recommend the right fit and explain the tradeoffs clearly.
Vinyl Sheet Pile
The most common choice for residential canal and bay-front properties in the Keys. Vinyl sheet pile is immune to saltwater corrosion, requires minimal maintenance, and installs efficiently. Well-suited for moderate tidal exposure and standard residential applications.
Concrete Seawalls
Precast and poured-in-place concrete seawalls provide maximum structural strength for high-exposure locations and heavier loading requirements. The preferred solution for commercial properties, marinas, and sites facing significant wave and surge activity.
Rip-Rap Seawalls
Rip-rap — placed rock or rubble — is a cost-effective shoreline protection method that allows natural water movement while dissipating wave energy. Often used in combination with other systems or where a natural aesthetic is preferred.
When to replace
your seawall.
Proactive replacement is almost always less expensive than emergency repair after storm damage or a failure. If your seawall is showing any of the following signs, an assessment is worth scheduling before the next hurricane season.
