In a project run by the Army Corps of Engineers in Cape Hatteras, North Carolina, our product overcame a unique problem with a successful solution.
Due to relentlessly fierce marine conditions, the US Army Corps of Engineers (USACE) and the National Park Service set out to replace the seawall on Harkers Island.
The new seawall had to protect the shoreline from the harsh environment, but it also had to drive through North Carolina “black rock,” or hard black sandstone, formed by compression and cementation which renders it nearly impenetrable.
We recommended our 4.1 EverLast Series sheet piling because it is uniquely durable. The contractor was amazed at its rigidity, saying that “this was the hardest driving I have ever done.”
The 14,000 pound plate compactor drove the 4.1 sheet piling not only through black rock, but also into old concrete remains of a World War II bunker. Because of the durability of the vinyl sheeting, it was not necessary to use a “shoe” to protect it from the force of the hammer.
