How to Spot Signs of Rust and Corrosion

Boat docks require regular inspections for splinters, cracks, warped planks, and damaged handrails. A professional inspection will also look for rotting wood, which can compromise safety and structural integrity.

A periodic check for rust is important because metal sections may need to be replaced as soon as damage occurs. Staining and sealing your dock will also help protect it from future damage. Contact Boat Dock Restoration now!

No matter how hard you try to maintain your dock, there will be a time when the inevitable signs of wear and tear start to show. Even the strongest, most durable docks suffer from some degree of deterioration and damage over time, especially in salt water environments. Performing regular safety and quality inspections will allow you to spot problems before they become more serious and costly. Some of these issues can be repaired, while others may require a full replacement.

Cracks and Warps

If your boat dock is experiencing cracked or warped boards, it’s likely time for a replacement. These issues can make it harder to dock boats, and they’re also dangerous for anyone standing on them. It’s important to check the condition of your dock regularly and compare it to previous pictures in order to spot any changes or red flags.

Wood Rot

Wood and salt water don’t mix well, and over time, this can lead to rotting. If the rotting affects only specific areas of your dock, it may be possible to repair them by sanding away the rotted area and adding new wood boards. However, if the entire board is rotting, it’s more likely that your dock will need to be replaced.

Metal Rust

Any dock with metal components is susceptible to rusting, as corrosive salt water can quickly eat through the metal. Small rust spots can often be fixed, but if the rust is widespread and visible from different angles, your dock is likely beyond repair and will need to be replaced.

Dock Supports Warping

The constant pressure of waves and currents can cause a dock to warp over time. If the warping is limited to a few key areas of your dock, it’s possible to replace the individual components, depending on your dock’s materials. However, if major load-bearing areas are warping or showing significant breakage, it’s likely best to replace the entire dock to ensure structural integrity.

Modular Dock sections can be attached to the main dock to provide easy access for loading and unloading boats, as well as make it easier to embark, disembark, and park a boat. If any of these modular sections are starting to droop or become wobbly, this is a sign that there is a problem with the foundation or anchors. It’s important to get these repairs done as soon as you can, as these problems can be difficult to fix and could result in further damage if not caught early.

Rust

Because docks are constantly exposed to water, they can experience damage from a variety of sources. These can include weather, waves, winds and temperature changes that cause expansion and contraction of the dock materials, which can lead to cracks, warps and rot. But they are also vulnerable to more serious issues like rust and corrosion. Rust can be particularly dangerous, especially in metal dock structures, because it eats away at the material and weakens the structure. Keeping an eye out for the early signs of rust is important, so that the issue can be addressed quickly before it progresses to significant and costly problems.

Wood docks are just as susceptible to the ravages of rust as their metal counterparts, particularly when they have not been protected with stain and sealants. In fact, a regular application of an EPA-approved rust remover can help prevent rust and extend the life of a wood dock. Choose a product that is free of harsh chemicals, such as antibacterial agents, chlorine bleaches, disinfectants, phthalates, phosphates and phosphorus, which can damage the deck boards and other wood surfaces.

Performing regular safety and quality inspections is the best way to identify potential dock issues before they become serious problems that require costly repair or replacement. Inspectors should look for obvious warping, sagging and erosion as well as any signs of cracks or rotting of boards. They should also check the condition of the dock’s supports, including pilings and beams, which are especially prone to corrosion.

If the frames of the dock are damaged, it may be possible to repair them with spot repairs or, if the damage is significant, they might need to be replaced entirely. A professional will assess the extent of the damage and determine the best course of action.

Docks are often located on lakes, rivers and other bodies of water where the currents can create undue pressure on the structures. In some cases, these forces can even cause the supports to shift or buckle, which can be quite dangerous for anyone standing on the dock. Having an expert inspect the structure on a regular basis can catch any shifts or cracks before they impact the integrity of the dock.

Foundation Deterioration

A boat dock is exposed to constant water and weather elements, which takes a toll on materials. Over time, these factors can weaken the foundation of a dock, especially its pilings. This can cause the structure to degrade and ultimately collapse. Knowing how to spot the signs of a failing foundation can help you decide whether to repair the dock or replace it entirely.

Wooden docks are susceptible to rot and decay from fungal growth and moisture exposure. If you notice that certain areas of your dock have begun to rot, it is important to take action right away. Small areas of rotting can usually be treated with chemicals, while widespread rot may be an indication that the entire dock needs to be replaced.

Dock pilings are the long, column-like structures that hold up the rest of the structure. These buried supports transfer the full load of the dock into layers of earth beneath the surface. Pilings are extremely important, as they allow the dock to withstand extreme pressure from currents, waves, and marine life. Foundation deterioration is dangerous because the dock could come crashing down into the water at the slightest of nudges.

While you can often perform minor repairs on your own, such as removing algae, replacing rusted screws, or repairing deck boards, it is always a good idea to contact professionals for any major work. These professionals can help you evaluate the condition of your dock, recommend repairs, and even replace your entire dock if necessary.

Getting regular inspections and performing maintenance tasks can also help extend the lifespan of your dock and reduce the need for costly repairs in the future. Inspecting your dock regularly, addressing problems immediately, and applying protective coatings can all keep your dock in pristine condition.

Whether you have a wooden, metal, or floating dock, it is important to assess the condition of your structure at least once a year. Changes in tide levels, fluctuating weather conditions, and marine organisms like barnacles can all impact the stability of your dock.

Floating Docks

While floating docks do work well for some waterfront properties, they are best suited to protected, calm areas. If you live near a busy marina, for example, you might prefer something more stable and anchored to the bottom of the lake or river to avoid boat propeller damage. It’s important to have a professional inspect your floating dock regularly to make sure it is safe and functioning properly.

Floating docks are typically built from buoyant materials like polyethylene, which helps them keep afloat. These materials can degrade over time, and it’s common for a single float to need replacement from time to time. It’s also important to check for other issues, like stress cracks or erosion at the joints, that may not show up as a visible problem until it is too late.

Once you’ve identified all the potential problems, it’s important to assess whether a minor repair is possible or if you need to replace a damaged section of the dock. If the dock is constructed from wood, for instance, you can replace individual boards and beams that aren’t load-bearing, but it’s usually necessary to replace the entire section if major damage occurs.

If your floating dock is made from plastic, on the other hand, it’s much easier to repair surface scratches and minor damage. A plastic welding iron can be used to melt the damaged area and fill it with a matching material to restore strength and appearance.

Floating dock sections are held together with coupler systems that help them sustain various weight and stress levels. EZ dock couplers, for example, are crafted from environmentally-friendly recycled rubber that absorbs shock and withstands heavy loads, which eliminates the need for screws, bolts, and nails that can corrode over time.

It’s crucial to regularly wash your floating dock to remove salts from the surface and prevent rusting. You should also apply a protective coat of sealant to metal parts, especially if they’re exposed to constant contact with salt water. In addition, you can add anodes to the dock that will serve as sacrificial metals to protect your other materials from corrosion.
