Endurance Composite Seawalls

The Endurance Marine Composite represents the Pinnacle of Performance in today’s ever changing composite industry. This first ever infrastructure-grade marine composite is composed of a patent-pending carbon-enhanced resin system and superior fiber reinforcing matrix. The unique combination places the Endurance composite in a class of its own.

To insure high reliability and performance, the Endurance composite as well as actual manufactured sheet pile parts are rigorously tested by independent ISO 9002 and A2LA registered test facilities on a routine, random basis.

We Consistently Receive the Ultimate Compliment.

Every Northstar competitor has a product that it wants to compare to Northstar's Endurance Composite, which is a real compliment.  However, since it's somewhat easy to create a product that "appears" to be similar, specifiers should be wary of products that compare themselves to Endurance. Testing of actual physical parts by an independent ISO 9002 or A2LA laboratory is the only credible method of determining the suitability of a product for a given application. If competitors can't provide comprehensive test data at your request, then you should expect your project to be their proving ground.

Two years later, the new dune has regained its natural look.

Compare an Endurance Seawall to a competitive seawall and you'll see something on their wall that you won't see on an Endurance wall - expensive structural components (wales and piles) that require maintenance over time. Why don't you see these same components on an Endurance wall? Because Endurance is over ten times stronger than a conventional vinyl seawall!

Northstar supports the formation of a standardized industry-wide testing regiment for synthetic sheet piling. Until industry accepted test protocols are established, engineers and Specifiers should require third party verifcation of a manufacturer's published specification and should apply conservative safety factors to products lacking reliable certifications.

Optional Carbon Long Fiber Reinforcments Add Unbelievable Strength to Composite Sheet Piling.

This patent-pending option adds long-fiber carbon einforcements to insure long-term stability from a composite interlock system!

Northstar introduces CRItm (carbon-reinforced interlocks), a new patent-pending option on Endurance CSP profiles. This new interlock option dramatically improves the strength and durability of these superior profiles and sets a new standard for the peformance of composite sheet piling! A similar option adds carbon long-fiber reinforcement to the corner sections of composite profiles, producing dramatic increases in performance.

This 17' exposed Endurance wall protects a deteoriating Naval waterfront facility in Norfolk, VA. A concrete cap tied back into the existing structure will be the wall's only support.

Endurance was manufactured in an attractive Sand color for the developer of this exclusive Florida waterfront project. In this project, Endurance POLARIS Series was more economical than a heavy vinyl sheet pile option.
