Engineers and Designers

Environmentally friendly

Will not leach carcinogens (like chromium and arsenic as with CCA treated wood) into the environment.

Regulatory friendly

More and more jurisdictions are banning CCA treated wood in sensitive waters.

Customizable geometries

Moments of inertia can be tailored to specific loads and applications.

Energy absorbing

Protects vessels from damage in case of collision.

Tremendous strength to weight ratio.

Contractors / Builders

Increased production

Piles are driven much faster than solid piles.

Increased penetration

Driving refusal is typically deeper than solid piles, enhancing structural performance.


Can be filled with concrete or other fillers after driving.

Reduced equipment requirements

Vastly lighter than wood, concrete, or steel.



Absolutely the most attractive option available for dock pilings.


Provides a strong, lasting foundation which will lower the life cycle cost compared to traditional piling options. Your foundation needs to outlast the materials you put on it.


No pesticides.

I was going to use wood pilings until I realized the foundation wouldn't outlast the dock.

When Hurricane Matthew struck, I found out the hard way that the tops of my piles were rotten. The wind and the upsurge ripped the stringers right off but the new section built with Fortress Pilings held tight.

Fortress Pilings will stand the test of time with only a modest increase in the overall project cost.

It just didn’t make sense to put something that will last practically forever on top of piles that will eventually rot. That is why we choose Fortress Pilings.
