Each year, ocean borers like shipworms and similar species cause millions of dollars in damage to wooden marine infrastructure worldwide. These pests, with their abundant larvae and high dispersal potential, threaten the lifespan of wooden docks, piers, boats, and shoreline stabilization structures in coastal environments. Despite the severity of the issue, no treatment completely protects wood from shipworms.
What Are Shipworms?
Shipworms, often referred to as “sea termites” by marine contractors, are not insects or worms. These wood-boring pests are mollusks that thrive in saltwater and breathe oxygen through gills. They consume wood as a food source but cannot survive without water.
Once shipworms infest a dock’s pilings, they burrow relentlessly until the wood is hollowed out, creating a serious safety hazard. A compromised dock could collapse, posing risks to anyone on it.

Repairing Shipworms Dock Piling Damage
Wooden dock pilings damaged by shipworms or other marine pests are not beyond saving. The SnapJacket Repair System from Shoreline Plastics in Jacksonville, Florida, offers an effective solution.
What Is SnapJacket?
SnapJacket is a durable vinyl piling jacket designed to repair, protect, and reinforce wooden pilings in marine environments. This cost-effective, environmentally friendly system preserves aging pilings and prevents further damage from wood-destroying organisms.
The SnapJacket Repair System uses a UV-protected vinyl sleeve that encases damaged pilings, halting deterioration caused by marine borers like shipworms. By protecting existing pilings, it extends their service life and eliminates the need for expensive replacements. The system’s straightforward installation process avoids disassembly of structures above the pilings, making it both practical and time-efficient. SnapJacket’s durable design reduces site disruption and minimizes labor costs, making it a cost-effective choice for dock owners.
In addition to its financial benefits, SnapJacket is an environmentally sustainable option. By preserving existing pilings, it reduces waste and conserves natural resources. The vinyl material is recyclable, ensuring a lower environmental impact compared to other piling repair methods.
SnapJacket’s user-friendly design simplifies the repair process. Installation is quick, as there is no need to remove the original pilings. This approach not only enhances safety but also ensures minimal downtime for dock projects, increasing productivity for contractors and homeowners alike.

Preventing Damage in New Dock Construction
The best way to avoid dock piling damage is to use materials resistant to shipworms from the start. For new construction, consider the EcoPile System from Shoreline Plastics.
What Is EcoPile?
EcoPile is a patent-pending vinyl-fiberglass composite marine piling engineered to withstand harsh marine environments. Unlike traditional wood pilings, EcoPile is impervious to ocean borers, completely recyclable, and free from leaching pollutants.
Designed to outlast wood pilings, EcoPile provides long-term durability for docks, boat lifts, and boathouses. The material is borer-resistant, ensuring pests like shipworms cannot cause damage. Furthermore, EcoPile meets stringent environmental standards, offering a sustainable alternative to pressure-treated timber. By eliminating the need for treated wood, EcoPile supports the growing demand for environmentally responsible marine construction.
