Seawall Construction & Replacement for Key Biscayne waterfront properties

When a Key Biscayne seawall is past repairing, the job becomes a replacement: the old wall comes out and a new one goes in. We design, build, remove and repair seawalls and coastal structures, and we work closely with licensed engineers to evaluate the site and settle on the design.

Walls are built in engineered sheetpile, concrete and timber, and the shoreline work extends to riprap revetments, jetties and breakwaters. The design follows the site: soil conditions, water depth and the layout of the property. Materials run to concrete, vinyl, steel and composite systems.

We manage the project end to end, from site assessment and engineered design through permitting support, construction and the post-construction inspection. Our marine-capable equipment includes crane barges and work barges, which let us reach Key Biscayne sites that land equipment cannot. More about seawall construction.
