Riprap Revetments Explained:
JSC Contracting’s Rugged, Natural Shoreline Armor Riprap revetments are rock-armored slopes that dissipate wave energy, stop erosion, and blend with Florida’s landscape—a DEP-favored, low-maintenance alternative to concrete seawalls. In Central Florida’s lakes and rivers, where boat wakes and storm surges chew shorelines at 1–3 ft/year, riprap is FBC-compliant, FEMA-eligible, and insurance-smart (up to 10–20% NFIP savings).JSC Contracting Inc (Ocala, FL) builds engineered riprap systems with graded limestone, geotextile fabric, and vegetated caps—protecting waterfront homes in Marion, Lake, Sumter, Citrus, and Brevard. With 34+ years from Labagh Marine, license CRC1332267, and top 1% BuildZoom score, JSC delivers 50-year durability at half the cost of vinyl.
