Why You Should Choose Treated Wood Piling For Your Deck


Choosing sturdy, high-quality piling is key for a structurally sound dock. Because every part of the dock relies on the pilings, they must be strong, durable, and straight. Wood alone may meet these demands, however, treated wood pilings can handle being immersed in brackish or saltwater while still maintaining their integrity.

Treated wood pilings offer protection against decay and marine life, such as shipworms and boring clams. The outer layer of the wood is injected with a chemical preservative, chromated copper arsenate, to help create a protective envelope around the heartwood, the inner part of the timer. The viability of the protection depends on how deeply the treatment penetrates the wood and how well the wood holds on to the treatment. Different regions across the country may call for different treatment strengths, however, for dock pilings, it is best to use the strongest available.

Treated wood pilings offer the same advantages of wood piling, while also resisting rot. With 2.5 CCA—the maximum treatment for salt-water immersion—Decks & Docks’ treated wood piling is meant to support your dock for years to come. With lengths up to 60 feet, our treated wood piling is sure to meet your lumber needs for your next dock project, whether you’re building on a canal, lake, river, or shore.


Once you’ve decided that treated wood piling is right for your project, make sure that you check for the following features.

Treated wood piling is:

  • AFFORDABLE. Wood piling can be less expensive than fiberglass and Greenheart wood piling. While price alone should never be a deciding factor, we understand it can be an important variable for a project.
  • LONG LASTING. Treated wood is made longer-lasting thanks to the protective barrier that limits damage to the heartwood. By resisting rot and damaging marine organisms, treatment extends the lifespan of wood pilings.
  • STRONG. In addition to standing up to being driven into the ground, treated wood piling can also support your decking and dock accessories. Plus, it holds up to the ebbs and flows of the currents.
  • DURABLE. Whether you are using your dock for sightseeing, fishing, or as a launch pad, wood pilings will stand up to the wear and tear.
  • ATTRACTIVE. Wooden docks are a common sight. For many boaters, they’re the only way to go. There’s something reassuring about the look of the wood and its proven usefulness and longevity. In addition, wood pilings can be stained, sanded, or painted as desired.
  • MODIFIABLE. Wood can be cut on site if needed or shaped. This can make it easier to work with than other pilings, allowing for modifications as necessary for a successful project.

Wood pilings have been used to elevate homes for around 6,000 years. Even the famed Roman aqueducts were supported on timber piles (which are still in good condition almost 2,000 years later). Timber pilings have proven themselves effective for supporting coastal homes, telephone and electrical cables, and docks. They are versatile and, when properly embedded, will last a long time. When treated, wood pilings last even longer. They can better stand up to humidity, brackish or saltwater, and marine organisms.

Remember The Caps


Because your pilings are an integral part of your dock, it’s a wise decision to protect them before embedding them to ensure longevity. Pile sleeves can help protect the part of your piling that is actually embedded in the ground.
While there are solutions for protecting piles after they’ve already been embedded, protecting them from the start can save you time and help ensure your dock is protected from the outset.


To further protect your dock, make sure to use piling caps. Piling caps aren’t just a stylistic option. They can help protect your pilings from sun damage, ensuring their longevity. Piling caps also discourage birds from roosting and deflect rain, all of which will help your pilings last longer.
