Strut Arm Pontoons: The Installation Process

Strut arm pontoons are a top-notch choice for residential and commercial waterfronts, thanks to their superior stability and durability. Unlike cable pontoons or piled pontoons, strut arm pontoons use fixed-arm pontoon systems that provide a stable mooring solution even in changing water conditions. This design makes them ideal for private jetties, residential docks, and marinas where performance and reliability matter most.

At Micks Marine Maintenance, we’ve seen firsthand how strut-mounted floating docks can transform waterfront spaces. These systems combine marine-grade pontoon construction with innovative engineering to deliver long-lasting performance. Proper installation is vital to ensure you get the most out of your pontoon and avoid unnecessary repairs down the line.

This guide walks you through the step-by-step process of installing strut arm pontoons, covering everything from site assessments to final safety checks. If you’re located in Yamba, Tweed Heads, Gold Coast, Brisbane, Bribie Island, or the Sunshine Coast, our team can ensure a seamless installation. Whether you’re upgrading your waterfront property or building a new mooring system, we’re here to help deliver a stable and reliable solution.

Site Assessment & Planning

Before installing strut pontoons, selecting the right location and conducting a thorough structural assessment is essential. A well-planned site ensures your pontoon will perform reliably, adapt to changing conditions, and provide long-term stability. At Micks Marine Maintenance, we know from experience that overlooking this step can lead to costly adjustments later. That’s why we always prioritise detailed site suitability analysis to deliver the best results for our clients.

Key Steps in Site Assessment

1. Water Depth & Tide Movement Analysis: We measure the water depth and observe tidal fluctuation adaptation to ensure the pontoon operates smoothly during both high and low tide. This step ensures the structure remains functional, no matter the water level.
2. Load-Bearing Assessment: Understanding the expected load-bearing capacity is critical. We assess the structural needs based on the size and weight of vessels, as well as anticipated foot traffic. This process guarantees that the pontoon remains strong under regular use.
3. Environmental Factors: Evaluating wave exposure, wind impact, and seabed conditions ensures safe anchoring and structural integrity. For example, areas exposed to strong waves may require additional reinforcement or specific designs to secure the pontoon.
4. Compliance & Approvals: Local council compliance is crucial for any pontoon installation. We ensure that all necessary approvals from marine authorities are in place before beginning construction. This step prevents delays and ensures your project meets all legal requirements.
5. Choosing the Best Pontoon Size & Materials: Selecting marine-grade materials tailored to the site conditions is the final step. We use materials that withstand harsh marine environments, ensuring their durability and longevity. Also read, Essential Considerations for Selecting the Ideal Pontoon Size

Tip: Waterfront property owners in Yamba, Tweed Heads, and the Gold Coast should consider storm resilience during site suitability analysis. Opting for materials and designs that withstand extreme weather conditions can save time and money in the long run.

A comprehensive site assessment not only ensures a smooth installation process but also guarantees that your strut arm pontoon will perform reliably over time.

Preparing the Strut Arm Pontoon Components

Before installing a strut arm pontoon, you need to ensure all components are properly prepared and assembled. Each part plays a crucial role in ensuring the structure’s durability, functionality, and safety. We follow a systematic process to deliver a seamless, long-lasting floating dock installation.

Key Preparation Steps

1. Inspect & Prepare Strut Arms: Start by examining the strut arms to ensure they are made of galvanised steel or marine-grade aluminium. These materials provide the durability needed to withstand harsh marine conditions. Confirm there are no defects or weak points that could compromise their strength or performance.
2. Pre-assemble Fixed Support Brackets: Assemble and align the support brackets that connect the pontoon to the shoreline. A properly aligned fixed support structure ensures the pontoon remains stable and functional during use. We always double-check this alignment to prevent future movement or imbalance.
3. Decking & Buoyancy Components Check: Inspect the decking material to confirm it meets marine standards. Choose marine-grade aluminium decking, marine carpet, or other suitable materials that are non-slip, UV-resistant, and securely sealed. This step ensures the non-slip pontoon surface remains safe and long-lasting for regular use.

Installing the Fixed Strut Arms

Micks Marine Maintenance takes care to ensure the fixed strut arms are installed correctly for a stable and reliable cantilevered pontoon system. Here’s how we manage the process step by step.

1. Position the Shoreline Mounts: We begin by securing the shoreline brackets to a reinforced concrete base. These mounts form the foundation of the strut arm bracket installation, so their stability underpins the entire system.
2. Align & Bolt the Strut Arms: The strut arms are then aligned with precision and bolted into place. Getting the alignment correct allows smooth pivot movement and prevents unnecessary stress on the pontoon structure.
3. Check Load Distribution: Once the arms are in place, we assess the distribution of weight across the system. Uneven loads can lead to strain and long-term structural issues, so we ensure the load distribution is balanced to maintain the pontoon’s integrity.
4. Secure the Arm to the Pontoon: The free-floating ends of the strut arms are attached to the pontoon deck using flexible connectors. This connection allows the pontoon to adjust to natural movements in the water while remaining securely fixed to the shoreline.

Tip: Adjusting the tension in the strut arms is crucial in areas like Brisbane and Bribie Island, where water levels fluctuate. Our team pays special attention to this during installation to prevent future issues and provide optimal support.

Final Adjustments & Safety Checks

The final steps of installing a strut pontoon ensure safety, functionality, and compliance. We conduct a thorough process to provide you with peace of mind and a durable pontoon.

Final Steps

1. Inspect All Fixings & Load Points: Our team carefully inspects each bolt, bracket, and anchor point, tightening any loose connections. A secure fixing is essential to structural reinforcement checks and maintaining stability under regular use.
2. Test Pontoon Movement: We test the pontoon’s movement, ensuring it glides smoothly vertically without any unwanted lateral shifts. This step ensures the structure holds up to wave and current resistance testing, providing reliable performance in varying water conditions.
3. Apply Finishing Touches: Next, we add the final elements like mooring cleats, handrails, and gangway connections. Each fixture is installed with care, ensuring functionality and compliance with marine regulations.
4. Conduct Safety Inspection: We perform a detailed pontoon safety inspection, looking for sharp edges, weak points, or misaligned fixtures. This critical step ensures the pontoon is user-friendly and meets all safety standards before handover.
5. Obtain Final Approval: If council approval is required, we assist with the necessary inspections to ensure everything complies with local marine regulations. Our expertise helps streamline the approval process, saving you time and hassle.

Tip: To enhance long-term use, we recommend a non-slip surface finishing, like marine carpet. This provides added safety and ensures the decking remains durable and practical in wet conditions.
