Miami-Dade County has invested over $4 billion in sea-level rise adaptation, and for good reason — local tide gauges show Biscayne Bay rising roughly 1 inch per decade, a rate that puts aging 1960s-era seawalls under compounding stress. The combination of chloride intrusion, thermal expansion in Miami's extreme heat, and regular wave action from boat traffic in the Miami River creates multi-directional cracking patterns that worsen exponentially if left untreated. Early polyurethane injection to seal voids and install proper relief drain systems can extend a Miami seawall's service life by 15–25 years.
We serve waterfront properties along Biscayne Bay, the Miami River, the Intracoastal Waterway, the Coral Gables Waterway, and the finger canals of Coconut Grove and the islands. Service areas include Coral Gables, Coconut Grove, Morningside, Belle Meade, Venetian Islands. Call 866-398-9323 for a free on-site inspection at your specific address.

Aggressive tidal saltwater plus worsening king-tide flooding; many mid-century seawalls in Coral Gables, the Grove and the islands now sit below DERM's required cap height; Biscayne Bay wave and boat-wake exposure cracks caps and fails tie-backs.
"Our Coconut Grove seawall was in terrible shape — chunks falling off, visible rust stains. Solid Foundations injected polyurethane foam behind the wall, installed relief drains, and it looks and performs like new. Highly recommend."
