Synthetic sheet piling

CMI is the worldwide expert in the synthetic sheet piling, offering vinyl, composite and aluminum products as alternatives to steel, concrete and wood sheet piling structures. CMI has the world’s largest vinyl sheet piling fabrication facility, specifically designed to incorporate new advancements in manufacturing technologies. The advanced materials process reduces the carbon footprint of manufacturing and increases the level of quality control. CMI is the only vinyl sheet piling manufacturer to be tested and approved by the United States Army Corps of Engineers and the NRCS. Our products are American made and our research team has patented over two dozen new products and technologies.

The main application areas of these products are in:

  • Flood Protection
  • Water Control
  • Cut-Off and Containment
  • Marine Structures

These sheet piling products have also been used in some of the most challenging chemical containment, levee seepage, and groundwater cut-off projects including ShoreGuard® and UltraCompositeTM being used in remediation projects for Environmental Protection Agency.

Further, following are few of the key products that we supply

  • ShoreGuard
  • AlumiGuard
  • Ultracomposite


ShoreGuard is 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. Following are few key benefits of synthetic vinyl sheet:-

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


AlumiGuard and ArmorWare products allow us to build an entire wall system with highly durable aluminum components including sheets, anchor rods, caps and dead man anchors. Although aluminum sheets will drive and perform with the stiffness of a structural metal, aluminum is about one-third the weight of steel and has a very high strength-to-weight ratio which makes it cost effective to transport and easy to handle on the job site. Common Applications using aluminum sheet piling are:

  • Aluminum Seawalls or Bulkheads
  • Water Retaining Walls
  • Channel Walls 
  • Weirs 
  • Baffle Walls
  • Flood Walls

Marine grade aluminum sheet piling has been a material favorite because of its high strength to weight ratio and corrosion resistance. Aluminum sheet piling is an environmentally friendly product containing over 70% recycled material and is 100% recyclable. By choosing Marine and Military Grade aluminum alloys in the extrusion of AlumiGuard aluminum sheet piling, projects maximize the performance of their structure while minimizing the total lifetime costs. This alloy series is the best combination of strength and corrosion resistance for marine structures and other sheet pile walls.


UltraComposite, line of Fiberglass Reinforced Polymer (FRP) sheet piling, as an alternative to steel sheet piling. This product, manufactured in an ISO-certified production facility, presents a huge opportunity to make your project cost less, last longer, and leave a lower environmental impact. 

UltraComposite offers the following benefits over steel: 

  • Weighs 75% less than steel 
  • Corrosion resistant
  • Little to no maintenance 
  • No toxic preservatives
  • Low material and transportation costs
  • Can often be delivered to job sites with shorter lead times
