How Polystyrene Enhances the Performance of Jetties and Fenders

Jetties and fenders are crucial components in marine infrastructure, protecting vessels and shorelines from damage caused by waves, impacts, and docking maneuvers. Polystyrene insulation, especially Expanded Polystyrene (EPS), is widely used in these applications for its excellent buoyancy, shock absorption, and durability.

Why Polystyrene Is Ideal for Jetties and Fenders

Polystyrene’s lightweight and closed-cell structure provide superior flotation and energy absorption, making it ideal for marine bumpers and dock protection systems. 


Its resistance to water absorption ensures long-lasting performance even in harsh saltwater environments.

Advantages of Polystyrene in Jetties and Fenders

  • High buoyancy: Supports floating jetties and cushions vessels effectively.

  • Excellent shock absorption: Protects boats and structures during docking.

  • Water-resistant: Prevents degradation from constant water exposure.

  • Durable and lightweight: Easy to install and maintain with long service life.

  • Versatile: Can be shaped to fit diverse marine applications.

Common Applications

Polystyrene is used in floating and fixed jetties, as well as fender systems for marinas, commercial docks, and recreational boating facilities.

Conclusion

Polystyrene insulation significantly improves the functionality and lifespan of jetties and fenders by providing reliable buoyancy and impact protection. With proper installation and maintenance, polystyrene-based marine components deliver safe and durable solutions for waterfront infrastructure.
