How to Identify Signs of Damage in Concrete Docks

Concrete docks are strong and durable, they are built to handle everything from high foot traffic and strong waves. But with time, even the strongest structures will become weak due to exposure to the elements and this can cause wear and tear. And  if you’re not paying attention to it, these small issues will turn into major issues that need costly repairs.

So, how do you know if your concrete dock is showing signs of damage? This article will explore what to look for, what might be causing the problems and when you should call a professional for concrete dock repair.

Why Concrete Docks Still Need Regular Checks

Even though concrete docks are built to last, they live in a harsh environment which can take its toll on them over time. That’s why it’s important that you conduct regular inspections, it doesn’t matter whether you do them yourself or you hire someone. Catching these damages early will save you a lot of time and money.

Signs of Damage to Watch Out For

Here are some common warning signs that your concrete dock might be damaged:

• Cracks

Not all cracks mean the same thing. Small cracks are normal but wider, deeper cracks could mean there’s an issue with the structure or there’s movement in the foundation. If these cracks begin to spread, it’s time to take a closer look.

• Spalling

This is when the top layer of the concrete starts to peel or chip away. This problem is created when water gets into the concrete and expands when it freezes. Spalling can look like a minor problem but it’s a sign that your concrete dock is affected by water.

• Rust Stains

Rust stains could be anything but more importantly, it can be a sign the steel rebar inside the concrete is corroding. Once the rebar starts to rust, it expands and causes the concrete to crack or break.

• Algae or Mildew Buildup

This is not a technical problem but algae or mildew buildup on your dock is a sign that water is not draining as it should. It can make your dock dangerously slippery.

• Uneven or Sinking Areas

If parts of your dock are looking like part of it is sinking or tilting, it means there’s an issue with the base or support structure and this is very bad.

What Causes This Damage?

• Saltwater corrosion
• Freeze-thaw cycles
• Boat impact or floating debris
• Poor drainage
• Just plain old age

When to Call a Professional

If you see any major cracks or you notice uneven or sinking areas, the next best thing to do is to call a marine contractor. A professional can assess the damage and recommend the best solution before the problem gets worse. Even if everything looks fine, you should conduct an inspection at least once a year.

Conclusion

Concrete docks are strong but not indestructible. Whenever you notice any sign of damage, call a professional. Acting fast on these signs of damage will keep your dock safe and save you the cost of expensive repairs. Remember to conduct  dock inspections now and then. It’s always better to be proactive than to face costly repairs later on.
