Seawalls are massive structures that separate the land and ocean, preventing erosion and protecting areas from water. Old walls typically consist of vertical concrete slabs held in place by an anchor system and a steel-reinforced concrete cap. Seawalls can last for up to 50 years before they need serious repair or replacement. These frequently asked questions about seawall repair in Florida cover everything from soil stabilization to groundwater control.

Common Questions About Seawall Repair

What are some causes of seawall damage in Florida?

It’s rare for significant damage to occur to a seawall all at once. These massive retaining walls weaken slowly over time as they are exposed to the elements. Sometimes, a severe storm can deposit a lot of water against weakened walls, and the hydrostatic pressure that results can cause the seawall to shift its position or fail altogether. This can affect soil stabilization and cause sinkholes, or small holes can develop leaks.

What are the signs of erosion in seawalls?

Many old seawalls have survived for approximately 50 years when they were only designed for 30. Signs a wall is eroding include sinkholes behind it and cracks along the wall. These rust-colored fissures are warnings that the wall is at risk of failing soon. If the wall leans forward, soil stabilization is likely compromised, and backfill can leak through.

Does Florida’s Department of Environmental Protection (DEP) have seawall regulations?

Yes. Each district in the state has specific regulations, and permits are required for construction for any structure near or at the water. Property owners should contact their local DEP office to request more information. Contractors should be knowledgeable about the regulations and submit the required paperwork.

What materials are used in seawall repairs?

Vinyl and composite materials are often used for modern walls built around Florida waterways. Composite materials never corrode, are incredibly durable, and don’t leak toxic chemicals that can harm wildlife or organisms near the water. Wood and concrete are not as durable and shouldn’t be used.
