30+ Years Experience
Specialist External Water Leak Detection
Finding the source of an underground leak quickly can help prevent unnecessary water loss and increased water bills, property damage and disruptive excavation.
With over 30 years of industry experience, Moling Services South East provides specialist leak detection for external water mains, buried supply pipes and drainage systems across Kent and the South East. Our engineers assess the symptoms, investigate the affected pipework and use appropriate detection methods to narrow down the location of the fault.
Because MSSE also carries out water main repairs, supply pipe replacement, drainage repairs and trenchless moling, we can take the job beyond diagnosis and provide the most suitable repair or replacement solution where required.
Water Main Leak Detection
Leaks in private water mains can cause significant water loss, reduced pressure and damage to surrounding ground if left unresolved.
MSSE can investigate suspected faults in underground mains, narrow down the location of the leak and recommend the most appropriate repair or replacement solution.
Our experience with larger private water mains means we can manage both the detection work and any subsequent excavation, repair or renewal required.


Underground Water Leak Detection
Hidden leaks in buried water supply pipes can be difficult to locate from the surface.
Warning signs may include unusually high water usage, reduced pressure, unexplained wet patches or movement on the water meter when no water is being used.
MSSE specialises in locating leaks beneath gardens, driveways, paths and other external areas, helping identify the affected section of pipe before unnecessary excavation begins.
Drainage Leak Detection
Leaks within underground drainage systems can result from cracked pipes, displaced joints, root intrusion or other structural defects.
MSSE can investigate suspected drainage leaks using specialist inspection methods, including CCTV where appropriate, to assess the condition of the pipework and locate areas of concern.
Where damage is found, we can also advise on suitable cleaning, repair, relining or replacement options.

Signs You May Have an Underground Water Leak
Underground leaks are not always obvious, particularly when the damaged pipe is buried beneath a driveway, garden or other hard surface.
In many cases, the first warning signs appear elsewhere around the property. Look out for:
- Unexplained Water Usage: A noticeable increase in metered water consumption without any obvious change in how much water you are using.
- Reduced Water Pressure: A sudden or gradual drop in pressure at taps and outlets may indicate water escaping before it reaches the property.
- Wet or Soft Ground: Persistent damp patches, pooling water or unusually soft ground can sometimes indicate a leaking buried pipe.
- Water Meter Movement: If the meter continues to register usage when all taps and water-using appliances are turned off, there may be a leak on the supply.
- Recurring Drainage Problems: Persistent dampness, smells or unexplained ground movement can also point towards damage within an underground drainage system.
If you notice one or more of these signs, a professional leak investigation can help determine whether an underground fault is present and where further work may be required.
How We Locate External Water Leaks
No two underground leaks are exactly the same, so the detection method depends on the type of pipe, the suspected fault and the conditions around it.
MSSE uses specialist leak detection equipment to investigate buried water mains, supply pipes and drainage systems. Depending on the situation, this may include acoustic detection, thermal imaging, tracer gas testing and CCTV drain inspection to help narrow down the source of the problem.
By combining the most appropriate techniques, our engineers can identify the likely location of the leak as accurately as possible before excavation begins, helping reduce unnecessary digging and allowing any subsequent repair work to be targeted more effectively.

Find, Repair & Restore
Locating the leak is only the first step. Once the source of the problem has been identified, MSSE can carry out the necessary repair or replacement work to restore the affected water or drainage system.
Depending on the condition of the pipework, this may involve a targeted repair, replacing a damaged section, renewing a larger run of pipe or using trenchless impact moling where a new underground route is required.
Because the investigation and remedial work can be handled by the same experienced team, there is no need to coordinate separate contractors for detection, excavation and repair.

FAQs
The most common water leak questions… answered!
How can I tell if I have an underground water leak?
Common warning signs include unexplained increases in water usage, reduced pressure, persistent wet patches, unusually soft ground or movement on the water meter when all taps and appliances are turned off. Any of these can indicate a hidden leak on an underground supply pipe.
Can you have a water leak without knowing it?
Yes. Slow underground leaks can sometimes go unnoticed for weeks or even months, particularly if the water is escaping deep below ground or beneath a driveway, path or landscaped area. In some cases, higher water usage or reduced pressure may be the first clue.
How do professionals find hidden water leaks?
Leak detection specialists use a combination of techniques depending on the type of pipe and suspected fault. These can include acoustic detection, thermal imaging, tracer gas testing, pressure checks and CCTV inspection for drainage systems.
How long should I leave a suspected water leak before getting it checked?
It’s best to investigate a suspected leak as soon as possible. Even a relatively small underground leak can waste significant amounts of water over time and may worsen, potentially leading to ground damage, reduced pressure or more extensive repair work.
