Bald Head Island, North Carolina


Product:         Geotube® Marine Structures Technology

Application:   Jetties

Location:       Bald Head Island, North Carolina

Installation:   1995


The Challenge:

Bald Head Island has experienced serious beach erosion troubles since the mid-1970s.  The island was losing the shoreline battle.  A plan was needed to reclaim and protect the beach shoreline.

The Solution:

Geotube® marine containment technology was used for this shoreline project on the southernmost of North Carolina's cape islands.  A series of 16 Geotube® containers (30' circumference x 300' long) were installed perpendicular to the coast [photos 1 and 5].  The units were hydraulically pumped with dredge material [photo 2].  One third of the Geotube® containers were buried back to the island's dune line [photo 3].

The Results:

The width of the beach area increased after the Geotube® jetties were completed [photo 6].  Geotube® technology proved to be a cost-effective method of rebuilding the beach.

And in September 1996, only two days after the Geotube® installation, Hurricane Fran made landfall near Bald Head Island.  No erosion occurred as a result of that Category 3 hurricane.
