Saltwater-resistant materials for waterfront infrastructure and coastal projects.

The Challenge

The Problem: Saltwater Destroys Traditional Materials

Marine environments are the harshest test any structural material can face. Constant exposure to saltwater, tidal humidity, UV radiation, and biological fouling accelerates the degradation of wood, steel, and standard composites at rates that make maintenance budgets spiral out of control.

Marine-grade plywood delaminates within 3-7 years in submerged or splash-zone conditions. Galvanized steel corrodes and stains surrounding surfaces. Standard WPC boards absorb moisture, swell, and lose structural integrity. The result: costly replacement cycles, safety hazards, and environmental liability from treated-wood leaching into water systems.

The Miura Board Solution

Miura Board® is biologically inert. It does not absorb water, does not support mold or barnacle adhesion, and will not delaminate regardless of salinity or submersion time. Its fiber-reinforced plastic matrix is chemically identical whether exposed to freshwater, brackish estuary, or open ocean saltwater.

Municipalities, marina operators, and waterfront developers across the United States and internationally have replaced failing marine plywood and pressure-treated lumber with Miura Board® – achieving service lives that exceed 25+ years with zero maintenance interventions.

Case Study: Possum Creek Park, Gainesville, FL

The city replaced aging pressure-treated boardwalk sections with Miura Board® 4’x8′ panels. Post-installation monitoring confirmed zero delamination, zero water absorption, and no maintenance interventions required after three seasons of heavy public use and subtropical weather exposure.

Miura Board® carries no copper, arsenic, or chemical preservatives – eliminating the waterway contamination risk associated with pressure-treated lumber.
