Vinyl Sheet Piling

ShoreGuard® vinyl sheet pile provides a cost-effective and sustainable building material for seawalls and other sheet piling structures that are installed easier, resulting in shorter lead times and longer service-life over traditional materials, such as wood, concrete, or steel. CMI’s patented I-Beam Lock™ feature enforces the panels with greater strength and a tighter seal for a more reliable connection.

With advanced UV protection and co-extruded with XCR Technology™, ShoreGuard vinyl sheet piling is used to line national monuments such as the Jefferson Memorial in Washington D.C., international airports, and neighborhoods to provide flood protection in the face of extreme weather and climate concerns.

Flat Panel™ Sheet Piling

Flat Panel™ is a flat-front sheet pile profile for seawalls, retaining walls, flood protection and water control. This option provides an attractive alternative to corrugated sheet piling. Anchored, cantilevered or geo-grid supported walls can be designed using this advanced profile.

Aluminum Docks & Gangways

GatorDock® and Mantle Industries fabricated marine access systems are designed and built to be high performance, long lasting, cost-efficient solutions to harsh marine environments. With protective coating and corrosion resistance, our marine-grade Gator Aluminum™ reduces, and in many cases, eliminates maintenance requirements. Our aluminum structures won't crack like concrete, rust like steel or rot like wood.

Aluminum Bridges

From high-traffic pedestrian bridges to modular trail bridge systems for remote sites, GatorBridge® in-house engineering team designs and fabricates almost any type of bridge exclusively with Gator Aluminum™. Our aluminum bridges are proven to be more cost-efficient, more durable, and last longer than bridges made of other materials.

FRP Composite Sheet Piling

CMI’s fiber reinforced polymer (FRP) UltraComposite™ sheet pile and round pile products are more corrosion resistant, easier to handle and can provide substantial cost-savings during shipping and installation than steel and conventional materials. UltraComposite is used in thousands of commercial and private projects with the United States Army Corps of Engineers, US Fish and Wildlife Service, United States Navy and numerous state and local municipalities.

As the largest FRP sheet pile profile currently produced, UltraComposite products are domestically produced and piles are typically delivered to job site with lead times much shorter than steel.

Sheet Piling

UltraComposite™ sheet piling is an efficient and environmentally friendly alternative to steel sheet piling in marine structures, flood walls, and seepage barriers. It’s the strongest, most durable composite sheet piling profile available and often specified for bulkheads in areas that require heavier loading support than vinyl.

Round Pipe Piles

With the low transportation and handling costs, and no maintenance expenses, UltraComposite™ pipe piles are used for docks, piers, foundations, dolphin pile structures, mooring poles and more. These piles offer higher performance, corrosion resistance, less environmental impact, and lower life-cycle costs than wood, steel, or concrete.

Aluminum Sheet Piling

AlumiGuard™ is a line of high performance aluminum sheet piling and components from CMI used in the construction of seawalls, bulkheads and water control structures. AlumiGuard sheets drive and perform with the stiffness of a structural metal, but about one-third the weight of steel. AlumiGuard provides a higher strength-to-weight ratio – making it cost effective to transport and easy to handle on the job site. 

AlumiGuard sheet piling is both marine and military-grade, providing excellent corrosion resistance making it a high performing, low maintenance material in harsh marine environments like saltwater.

Polymer Encapsulated Treated Wood

TimberGuard® is CMI’s innovative line of polymer-protected wood pilings and lumber that are resistant to rot, UV and marine borer damage which are the main sources of traditional wood piling failure. These products are used in marine applications including seawall components, piers, docks and other projects or in conjunction with ShoreGuard®, GatorBridge®, and GatorDock®. 

TimberGuard requires little maintenance and can provide a longer life cycle and a cost-effective, safe alternative to treated wood. Our unique polymer protection system, available in multiple colors, is applied to the entire lumber piling with no need for fasteners. It does not adhere to the wood, which allows the piling to expand and contract naturally.
