What Causes Underground Pipe Damage

Nov 14, 2023

When it comes to maintaining your home, understanding the factors that can lead to underground pipe damage is important. In Darwin, where the climate and local conditions can be particularly harsh on infrastructure, being aware of these risks can save you time, money and a great deal of hassle. In this blog, we'll explore the various factors that contribute to underground pipe damage, helping you to stay informed and prepared.

The Common Culprits Of Underground Pipe Wear And Tear

It's not just the age of your pipes that can cause issues. Several factors contribute to the wear and tear of your underground plumbing.


  • Tree Root Intrusion: Tree roots seeking moisture can invade pipe joints and cracks, causing blockages or breakages. This intrusion can be so severe that it may lead to the complete collapse of the affected pipes.
  • Ground Movement: Shifting soil from seasonal changes or construction can displace pipes, leading to fractures. This movement can be subtle over time or sudden due to events like earthquakes or heavy construction activity.
  • Corrosion: The chemical composition of the soil, along with water quality, can corrode pipes over time. This process is accelerated if the pH level of the soil or water is too high or too low.
  • Pressure from Traffic: Heavy vehicles passing above can exert pressure on pipes, leading to damage. Repeated pressure in the same spot can weaken pipes until they eventually fail.
  • Inferior Pipe Materials: Older or lower-quality pipes are more susceptible to breaking down and causing problems. 

Top 5 Signs You May Have An Underground Leak

If you're concerned about potential leaks, keep an eye out for these telltale signs:


  • Unusually high water bills: A sudden spike in your water bill can often be the first indicator of a hidden leak underground.
  • Damp patches in your garden or lawn: These may indicate a leak below, especially if they appear without recent rain.
  • The sound of running water when pipes aren't in use: This could suggest water movement where it shouldn't be, possibly from a breach in the system.
  • A drop in water pressure: If water isn't flowing as strongly as usual, it could mean a leak is diverting the water away from its intended path.
  • Cracks in your foundation or walls: While these can be caused by various issues, they are sometimes the result of water damage from a leaking pipe.

Comparing Traditional And Modern Leak Detection Techniques

Leak detection has come a long way, with modern methods offering non-invasive and accurate results.


Traditional Methods

These often involved educated guesswork and could be quite invasive.


Modern Techniques

Professional plumbers use equipment like acoustic sensors to pinpoint leaks without disruption.

Is Your Property At Risk Of Underground Pipe Damage?

Intense dry spells can cause soil to contract, potentially leading to pipe movement and damage. Conversely, torrential rains can lead to ground saturation and shifting, both of which can exert unusual pressure on underground pipes. Regular checks are important, especially if your property has mature trees whose roots grow aggressively in search of water and can invade pipes. Heavy vehicle traffic can also compact soil and crush pipes below. If you've noticed any signs of leaks, such as unexplained moisture or the sound of running water, it's time to investigate the integrity of your underground plumbing.
