Hereford Inlet seawall repair project
Hereford Inlet is located on the New Jersey coastline, near the southeasternmost tip of the state, near Cape May. This project involved reconstructing the inlet's shoreline seawall. Portions of the structure were undermined by tidal scour and storm erosion. Failure of the seawall would pose a long-term threat to nearby buildings and other shoreline infrastructure. Strong tidal currents, steep underwater slopes, and deep-water sections meant that traditional construction methods would have been difficult to implement. The seawall is located on New Jersey's Atlantic Ocean shoreline. The site has maximum water depths of 60 ft. Underwater visibility is typically less than 3 ft. Strong tidal currents also affect the construction zone. A conventional solution would have involved installing an unsupported geotextile fabric to contain eroding soil. That fabric would then have been capped with bedding and armour stones to prevent the material from shifting and settling. The U.S. Army, Corps of Engineers concluded that this approach was impractical because of the challenging conditions at the site. Tensar Earth Technologies designed a 4-in.-thick Triton Biaxial (BX) Marine Mattress to encapsulate and support the geotextile material. Overall, each unit measures 4 in. high x 6.5 ft. wide x 20 ft. long. The design provided transverse compartments by specifying internal baffles at 2-ft. intervals. Each compartment was lined with nonwoven geotextile fabric and filled with 1.5- to 3-in. stones. Installation of a top panel completed the mattress assembly. Small stones in the mattress compartments helped anchor the geotextile until it could be lifted into place and secured with layers of armour stone
