Why Plastics Are Perfect for Marina Infrastructure

Benefits of Plastics in Tough Marina Environments

Marinas deal with some of the toughest conditions — constant exposure to water, salt, sun, and shifting temperatures can take a toll on any material. That's why you need something that can handle all that abuse, and plastics have become the go-to choice for marina gear. From docks to fenders, plastics like polyethylene and PVC have proven they can take the hits, resist UV damage, and hold up for the long haul.

At Piedmont Plastics, we provide top-tier plastic materials designed for the demanding marine environment. These materials give you long-lasting performance with little maintenance. Let’s examine the best plastic materials used around marinas and see how they keep things running smoothly year after year.

An Expert is just around the corner.

With over 100 years of combined product knowledge and industry experience, we are confident our plastics experts can help you find a solution for your application.

Superior Docking Systems

One of the key structures in any marina is the docking system. From floating docks to pilings and finger docks, polyethylene and PVC are widely used for their excellent durability, buoyancy, and weather resistance.

These plastics are highly impact-resistant and are not prone to rotting, rusting, or corroding like traditional materials such as wood or metal. In addition, polyethylene and PVC are lightweight, making them easy to install, while their low water absorption ensures minimal maintenance. The smooth surface of these materials also reduces friction, helping boats dock more gently and safely.

Bumpers and Fenders

Marina docks are constantly exposed to boat traffic, and dock bumpers and fenders take the brunt of the impact. PVC and polyethylene are ideal for these applications due to their excellent impact resistance and durability. These materials are engineered to absorb shock, protecting both the dock and the vessels.

Moreover, they resist UV degradation and keep their structural integrity even after prolonged sun exposure and water exposure. Marina operators can use these durable plastics to ensure long-lasting protection for their docks and boats with minimal upkeep.

Electrical Hookups

Marina water and electrical systems must be durable and reliable, especially in environments exposed to harsh weather conditions. Plastics like polycarbonate and ABS are ideal for this purpose due to their excellent weatherproofing capabilities.

These materials are often used in the casings of electrical pedestals and water hookups because they provide:

Impact Resistance and Transparency

Polycarbonate offers superior impact resistance and clear visibility while allowing secure access to controls.

Rigidity and Toughness

ABS is strong and can withstand wear, tear, and harsh environmental conditions.

Corrosion Resistance

Both materials are built to endure moisture, temperature fluctuations, and corrosion, ensuring long-lasting performance in marina settings.

Storage Lockers

Storage solutions must withstand moisture, salt, and UV light exposure in marine environments without deteriorating. High-density polyethylene (HDPE) is the go-to material for storage lockers at marinas because of its superior corrosion resistance and durability. HDPE is impervious to saltwater, making it ideal for the coastal environment.

Additionally, it’s lightweight, easy to clean, and requires virtually no maintenance, so marina operators can offer secure, long-lasting storage without constant repairs.

Kayak and Paddleboard Racks

PVC and HDPE are excellent material choices for rack frames and supports for storing lighter, non-motorized watercraft such as kayaks and paddleboards. These lightweight plastics make them easy to maneuver and provide the strength to support watercraft securely.

PVC is known for its flexibility and UV resistance, while HDPE offers exceptional impact resistance and durability, ensuring the racks can handle the wear and tear of frequent use.

Boat Lifts and Hoists

Regarding boat lifts and hoists, especially floating models, polyethylene is often used in buoyancy tanks and support structures. The material’s buoyant nature and resistance to water damage make it a perfect choice for these applications.

Polyethylene can withstand the weight of boats while providing the necessary support and floatation, making it a key part in many marina boat lift systems.

Protecting Docks from Waves

To keep marina docks safe from wave damage, HDPE is hands-down one of the best materials for floating breakwaters and barriers. Its buoyancy and durability make sure those waves get absorbed, keeping your docks and boats secure. Plus, HDPE can handle just about anything the marina throws at it—UV rays, saltwater, severe weather, you name it.

Here’s why HDPE floating breakwaters are a solid choice for wave protection:

  • Great buoyancy: It keeps the barriers steady and effective against rough waters.

  • Tough as nails: HDPE is built to last, even after years of exposure to the elements.

  • UV resistant: It won’t crack or fade from sun damage, so it lasts longer.

  • Saltwater proof: HDPE won't cause rust or corrosion to form in the marina environment.

  • Easy to maintain: These breakwaters need little upkeep, saving time and hassle.

Plastics Are the Future of Marina Infrastructure

Plastics like polyethylene, PVC, polycarbonate, and HDPE offer unmatched durability, low maintenance, and resistance to corrosion and weathering. These materials are lightweight, easy to install, and cost-effective, making them ideal for marina infrastructure. They help reduce the need for frequent repairs and replacements and ensure the marina remains functional and safe for years to come.
