Seawall Inspection & Repair in Coral Gables, FL

Walls on the Coral Gables Waterway sit in still, slightly fresh water and grow a thick layer of oysters that hides the concrete. Walls on the bayfront in Gables Estates take chop and wave action and lose sediment faster once a crack opens. In both places the diver cleans the wall first, then inspects it, then writes up its condition for the lender.

The city runs four tide stations on the Waterway that log water levels every 15 minutes, and the Cocoplum stations also track mangrove water levels, so the city knows how high the water gets behind these walls. What it doesn't know is whether your wall has a crack behind the oysters, and that is what the $250 inspection finds.

By one account the Coral Gables Waterway runs about 8 miles, from Biscayne Bay to Cartagena Plaza and then north along Riviera Drive toward the Biltmore, and the walls along it are lined with red, black and white mangroves that state law protects. A seawall inspection here works around the trees: the diver cleans and inspects the wall in the water and never trims a branch, and leaves the mangrove line for a county-certified trimmer if the owner ever needs one. The county manatee plan notes a stormwater outfall on a connected canal as a favorite freshwater spot, which is why Waterway walls carry softer growth than the bayfront ones in Gables Estates.

The Gables shoreline is mangrove-lined, and the state protects those trees, so seawall work here is done in the water without touching a branch; if a wall section is hidden by mangroves the diver works around them and says so in the documentation. Gables Estates walls on the bayfront lose sediment faster once cracked because they take chop; Waterway walls in Cocoplum carry more growth but sit in calmer water. For a sale the $250 inspection produces what the lender wants; for an owner who just wants to know, it produces a plain answer and a free quote for any crack.

How often a seawall should be looked at. Every 1–2 years, cleaned and inspected together, and after any named storm; seawalls get installed and forgotten until the yard loses sediment, and thick growth covers the crack that started it.
