Behind the Leaks: 6 Root Causes of Underground Pipe Leakage

Underground pipe leakage can wreak havoc on infrastructure, leading to water damage, structural issues, and expensive repairs. Understanding the root causes behind these leaks is essential for preventing and addressing them effectively. In this blog post, we will explore the six primary factors that contribute to underground pipe leakage. By gaining insights into these causes, you can take proactive measures to protect your plumbing system and avoid the costly consequences associated with leaks.


An important factor in underground pipe leaks is corrosion. Due to chemical interactions with the surrounding soil, water, or other elements, pipes can corrode over time. Corrosion can be sped up by elements including very acidic soil, aggressive water chemistry, and electrical currents. Commonly affected pipes include those made of iron, galvanised steel, or copper. Signs of corrosion include discolouration, pitting, or flaking on the pipe’s surface. Regular inspections, protective coatings, and utilising corrosion-resistant materials can help mitigate this issue. Additionally, addressing soil conditions, water treatment, and electrical grounding can significantly reduce the risk of corrosion-related leaks.

Poor Installation:

Inadequate installation practices can contribute to underground pipe leakage. Errors such as improper joint connections, insufficient pipe support, or incorrect slope alignment can lead to water seepage or pipe breakage. Over time, these issues can cause leaks to develop. It is crucial to hire experienced professionals who follow industry standards when installing underground pipes. A long-lasting and leak-free plumbing system depends on proper joint assembly procedures, suitable backfill compaction, and exact slope calculations. Regular inspections before, during, and after installation can find any possible problems early on, guaranteeing that your pipes are installed correctly and lowering the chance of future leaks.

Ground Movement/Settlement:

Natural ground movement and settlement can cause stress on underground pipes, leading to leakage. Pressure or movement can be created by elements like soil erosion, shifting foundations, or geological activity that harms the pipes. Joints may go out of alignment or under stress due to settlement, which may lead to leaks over time. Important preventive measures include performing a comprehensive evaluation of the soil conditions before installation and using appropriate pipe bedding procedures. Additionally, monitoring ground movement and promptly addressing any signs of settlement can help mitigate the risk of underground pipe leakage. Regular inspections and maintenance can help identify potential issues early and prevent major problems down the line.

High Water Pressure:

Excessive water pressure can strain pipes and cause them to develop leaks. When water pressure exceeds the recommended limits, it puts undue stress on the pipe walls, joints, and fittings. Over time, this strain weakens the pipes, leading to leakage. Installing pressure-reducing valves (PRVs) or pressure regulators can help regulate the water pressure and prevent excessive stress on the plumbing system. It is crucial to regularly check the water pressure and respond quickly to any spikes or anomalies. Maintaining the proper water pressure range ensures a dependable and effective plumbing system by preventing leaks and extending the life of your pipes.

Tree Root Intrusion:

Tree roots can invade underground pipes searching for water and nutrients, resulting in clogs, cracks, or joint displacement. Growing roots put a strain on the pipes, which causes leaks. Clay or older cast iron pipes are particularly vulnerable to root intrusion. Conducting regular inspections to identify any potential root intrusion points and removing or relocating trees away from the plumbing system can help prevent this issue. Long-term defence against leaks caused by tree roots can also be achieved by building root barriers or utilising pipe materials that are more resistant to root penetration.

External Forces and Physical Damage:

Underground pipe leaking can be caused by external forces such as excavation operations, construction projects, or unintentional damage. The pipes may suffer physical harm from heavy machinery, excavating tools, or even natural calamities like earthquakes. It is crucial to implement proper safety measures during construction or excavation projects to prevent accidental damage. Using locator services to identify the pipe’s location before digging and maintaining accurate records of the underground utility network can help avoid unnecessary damage. In areas prone to seismic activity, installing flexible pipe materials or implementing additional reinforcement techniques can help mitigate the risk of pipe damage and subsequent leakage.


Understanding the underlying causes of underground pipe leaks gives you the ability to take preventative action. By addressing factors such as corrosion, poor installation, ground movement, high water pressure, tree root intrusion, and external forces, you can safeguard your plumbing system and minimise the risk of leaks. You can guarantee a dependable and leak-free underground pipes network, maintaining the integrity of your infrastructure for years to come, with the proper care and attention.
