Riprap Shoreline Protection Installation

Riprap size is determined by wave energy, fetch length, and shoreline slope — not by aesthetics. We calculate the required D50 stone size using standard coastal engineering formulas. Using undersized stone is the most common riprap failure mode.

Properly designed and installed riprap with an adequate filter layer has a service life of 40–50+ years with minimal maintenance. Annual inspection is recommended to identify displaced stone or filter fabric compromise after storms.

In most cases, yes. Riprap installation in Florida typically requires DEP authorization as a coastal construction activity. Some counties have local exemptions for minor shoreline armoring. We assess permit requirements and handle all applications.

It depends on your specific situation. Riprap is often preferred for lower-wave exposures, gentle slopes, and properties where a natural aesthetic is valued. Vertical seawalls are typically required for high-energy wave environments, boat traffic, or where a hard edge is needed for dock access.

Yes. We install riprap along freshwater lake edges, river banks, and canal systems throughout Florida, Georgia, and South Carolina. The design approach is similar but adjusted for freshwater current and wave conditions.
