Fleximake’s Inflatable Buoyancy Bags (also known as Pontoon Air Lift Bags) provide safe, durable, and reusable flotation for marine equipment, submerged loads, and floating structures. Proudly designed and made in Australia, these rugged air-filled pontoons are built to withstand harsh marine, oil & gas, mining, and industrial environments.
✔ High-strength PVC-coated fabric – Tear, abrasion, UV, and chemical-resistant
✔ Integrated pressure relief valves – prevent over pressurisation
✔ Load-rated straps & certified shackles – Compliant with Australian Standards
✔ Custom or standard sizes – Cylindrical, pillow, rectangular & donut shapes available
✔ Compact & reusable – Easy to transport, deploy, and store
✅ Complete with all required accessories – Load-rated lifting straps and shackles compliant with Australian Standards.
✅ Integrated over-pressure relief valves, engineered to suit the bag’s volume and application.
✅ Even load distribution – Designed to maintain a minimum 1:6 safety ratio for slings.
✅ Durable high-performance materials – Made from high-tensile PVC-coated fabrics that are resistant to tearing, abrasion, and impact.
✅ Extreme environment ready – Resistant to UV exposure, saltwater, chemicals, and marine growth.
✅ Versatile design options – Available in standard cylindrical lift bags or customised shapes including pillow, rectangular, and donut styles.
✅ Compact and reusable – Submersible, easy to deflate and store.
✅ Marine & Construction: Floating walkways, pontoon bridges, pipeline and cable stabilisation,
✅ Aquaculture & Offshore: Cage support, floating platforms, equipment buoyancy
✅ Mining & Dredging: Pipe/cable flotation, submerged rig stabilisation
✅ Emergency & Defence: Salvage operations, rapid-deploy flotation systems.
