Vinyl Sheet Piling

CMI revolutionized the sheet piling industry more than thirty years ago with the introduction of ShoreGuard Vinyl Sheet Piling. Prior to that time, most seawalls, bulkheads and water control structures were made of steel, concrete, or treated wood. Many engineers working with these materials have faced a number of design and service issues. Steel rusts, is expensive and requires endless maintenance. Steel is also often coated with toxic chemicals to extend the service life, which can be harmful to the immediate environment. Concrete structures are subject to deterioration through settling, cracking, or the corrosion of the reinforcing steel. Often, additional deep foundations are required when using concrete adding unnecessary additional expenses. Treated wood leaches toxic chemicals, can be damaged by UV exposure, and is eventually compromised by fungus, bacteria, termites, or marine borers in brackish and saltwater.

On the other hand, ShoreGuard has provided a cost-effective and sustainable building material for seawalls and other sheet piling structures that can be installed easier and provide a long service-life without toxic coatings or preservatives. ShoreGuard Vinyl Sheet Piling is corrosion resistant, UV resistant and impervious to marine worm activity which has made it the top choice for engineers and contractors worldwide. Many now turn to CMI, the manufacturer of ShoreGuard Vinyl Sheet Piling, for solutions that offer incomparable benefits:

  • Cost-Effective
  • Sustainable
  • Easy Installation
  • Longer Service Life
  • Zero Toxic Coatings or Preservatives
  • Corrosion-Resistant
  • UV-Resistant
  • Impervious to Marine Worm Damage
  • Aesthetic Appeal

ShoreGuard has been thoroughly tested by the US Army Corps of Engineers (USACE) and widely used by the USACE, Natural Resource Conservation Service, EPA, Department of the Interior and many Fortune 500 companies.

The XCR Difference

Thirty years after the creation of ShoreGuard, it remains the best selling; most trusted synthetic sheet piling in the world. We believe that success is tied to our exclusive XCR Manufacturing Technology. XCR integrates state-of-the-art material processing, high precision co-extrusion technology, and vinyl formulations based on more than 65 years of experience. This results in the most corrosion and UV-resistant sheet piling available in the world.


As an industry leader for more than 65 years, CMI believes that we have a responsibility to future generations. We are committed to innovating sustainable solutions that revolutionize the industries we serve. We also prioritize sustainability and actively work to reduce our environmental impact in a number of ways:

Water Conservation

CMI’s manufacturing process is focused on water conservation and minimizing waste. In-facility recycling processes recirculate water used during the extrusion process and regrind imperfect product to be used again. CMI creates products that are not only recyclable and made from recycled content whenever possible, but have an inert impact on the environment once installed.

Recycled Content

Every product we manufacture is 100% recyclable. Our ShoreGuard sheet piling is manufactured using over 90% post-industrial recycled materials. CMI state-of-the-art facility grinds this material inside its facility to ensure only premier-quality materials are used in out finished products.

Carbon Footprint

We actively work to minimize our footprint in every step of our process: from manufacturing to transportation and installation.

FlatPanel Sheet Piling

CMI is committed to providing the construction and engineering communities with innovative and sustainable products. One of our newest products is the FlatPanel vinyl sheet piling profile (FP-475 and FP-575). CMI’s FlatPanel is an attractive alternative to traditional corrugated sheet piling offering updated aesthetics as well as engineered efficiency for stability and stiffness during drive episodes.
