Poly Pontoons

At G&M Poly, we take pride in being your trusted provider of custom-built pontoon boats and floatation devices in Australia. Our poly pontoons are crafted using high-density polyethylene (HDPE), a rugged and robust material that stands up to the toughest conditions. With HDPE as the primary material, our products offer exceptional resistance against UV rays, corrosion, and impact, guaranteeing a long-lasting investment that will withstand the test of time.

Advantages of HDPE Pontoons:

  • Natural Buoyancy: HDPE is naturally buoyant, ensuring that your pontoon boat stays afloat and stable on the water.
  • High Durability: Our pontoons are built to last. HDPE is a robust material that withstands harsh weather conditions, impacts, and UV radiation without losing its structural integrity.
  • Corrosion-Resistant: Unlike traditional materials, HDPE doesn’t corrode or rust when exposed to water, ensuring the longevity of your pontoon boat.
  • No Need for Painting: The inherent colour and properties of HDPE eliminate the need for painting, reducing maintenance efforts and costs.
  • Watertight Welding: Our highly experienced and qualified welders use advanced techniques to create watertight welds, ensuring that your pontoon remains 100% waterproof.

Floating Pontoons

Our floating pontoons are designed to withstand the rigours of any waterfront project, providing you with a reliable and long-lasting solution. Whether you’re building a marina, a floating dock, a boat lift, or any other water-based structure, our pontoons can be fully customised to suit your specific needs.

At G&M Poly, we want to ensure that your experience with our HDPE floating pontoons is as seamless and enjoyable as possible. Here are some installation and maintenance tips to help you make the most out of your floating platforms:


  1. Plan and Prepare: Before starting the installation process, carefully plan out the layout and configuration of your pontoon system. Take into consideration factors such as water depth, wave action, and anchoring requirements. It’s also important to acquire any necessary permits or permissions.
  2. Proper Anchoring: Ensure that your poly pontoons are securely anchored to the bottom using appropriate anchoring systems. Consult with a marine professional or engineer to determine the best anchoring method for your specific location and conditions.
  3. Follow Instructions: Always follow the manufacturer’s instructions and guidelines for installation. This includes using the recommended hardware, tools, and techniques. If you have any questions or concerns, don’t hesitate to reach out to the G&M Poly team for assistance.
  4. Safety First: During installation, prioritise safety by wearing appropriate personal protective equipment (PPE) and carrying out the work in a safe and controlled manner. Be aware of any potential hazards and take necessary precautions.


  1. Regular Inspections: Routinely inspect your floating pontoons for any signs of damage, wear, or loose components. Look for cracks, corrosion, or disengaged connections. Promptly address any issues to prevent further damage or safety risks.
  2. Cleaning: Regularly clean your pontoons to remove debris, algae, or other build-ups that may accumulate over time. Use mild detergent and water, along with a soft brush or sponge. Avoid using harsh chemicals or abrasive materials that could damage the pontoons’ surface.
  3. Avoid Heavy Loads: While HDPE pontoons are designed to withstand heavy loads, avoid exceeding the recommended weight limits. Overloading can cause stress on the platforms and compromise their structural integrity.
  4. Protect from UV Exposure: HDPE is inherently resistant to UV rays, but prolonged exposure to sunlight can cause slight colour fading over time. Consider using UV protective coatings or covers to minimise potential discolouration and extend the lifespan of your pontoons.
  5. Address Repairs Promptly: If you notice any damage or issues with your poly pontoons, such as cracks or loose connections, address them promptly. Contact G&M Poly or a professional repair service to assist with any necessary repairs.
