The Northstar System is a total seawall system which uses different components, any of which could be considered cutting-edge in its own right. The result is an unmatched, one-of-a-kind seawall system that's guaranteed for as long as you own your property.

The system begins with Northstar Vinyl Sheet Piling. Northstar profiles were developed and tested by independent third parties, allowing Northstar customers to choose the product with confidence! Northstar manufactures several versions of vinyl sheet piling so you can choose the profile that's right for your project. Northstar's patent pending design allocates structural vinyl compound at critical points along the cross section, optimizing strength, drivability and long-term performance.

The Northstar Seawall System is the only complete system guaranteed to stand up to the harsh marine environment. Northstar sheet piling is mono-extruded using 100% weatherable, impact modified structural vinyl. Mono-extruded means that the same material found on the face of the product is found at its core.

Some competitive products are made for less using a process called co-extrusion. Co-extrusion allows a manufacturer to "coat" the outer face of a profile with a high-quality material and substitute an inferior material for the inner core. Up to 98% of the total weight of a co-extruded product can be made with an inferior material. As a Northstar customer, you know what you are buying. Compare the Northstar System with any other seawall option and you'll agree that Northstar is "The smart choice."

"Why install a vinyl seawall when the chief structural component of the wall (the wood wale) is going to deteriorate?" That's been a tough question to answer.

Northstar pioneered and now proudly introduces another "First" for the marine construction industry.

For years, researchers have looked for a way to protect wooden marine structures from marine borers and the harsh marine environment.

Other vinyl seawall systems have to use treated lumber components in their wale and pile systems. "The Patent Pending Northstar System, which incorporates Northstar sheet piling with 21 Poly components is the only system on the market of its type."

21 Poly is a seamless polymer membrane that encapsulates marine treated (2.5 CCA) lumber and provides guaranteed long-term protection against marine borers.

This proprietary blend of compound was formulated specifically for treated lumber. 21 Poly actually bonds to the wood so you can cut it with a chainsaw without separating or fraying from the wood. Cuts are easily patched with a 21 Poly Field Patch Kit.
