Use advanced tools like thermal imaging, acoustic listening devices, and tracer gas for precise slab leak detection, and engage professional services for accurate, non-invasive repairs and preventive maintenance.
Understanding Slab Leaks
Water leaks, known as slab leaks, occur within a building's concrete foundation. They can happen due to poor construction practices, shifting soil, or pipe corrosion. If ignored, these leaks can cause severe problems for homeowners, including high water bills and weakened structural integrity.
Understanding the causes and signs of slab leaks is essential for controlling and preventing them. Taking effective measures early can help avoid widespread damage and costly repairs.
Common Causes of Slab Leaks
There are many reasons why leaks can occur in a concrete slab. Here are a few:
Corroded pipes, especially in older homes where the pipes have deteriorated and rusted
Poor construction methods where pipe connectors are misapplied and inferior sewerage pipes are used.
Bad piping system installation, which leaves them vulnerable to damage over time
These conditions can cause many leaks in the concrete foundation.
Soil movement also plays a significant role, as changes in soil moisture levels often trigger it. These movements can put pressure on sub-slab pipes and cause them to leak. High water pressure inside these pipes can overburden their structural integrity and cause breaks or ruptures that allow water to seep into the base structure. Knowing and identifying these triggers are the first steps in detecting and preventing slab leaks before they get out of hand.
Risks Associated with Slab Leaks
Slab leaks have many dangers; they worsen if they are not addressed quickly. One of the biggest is structural damage. Water under concrete floors can weaken a building's foundation and make it unstable. Undetected leaks mean higher water bills from water loss.
Another significant risk with slab leaks is mould growth. Moisture under concrete slabs is a perfect breeding ground for mould and mildew, which can harm residents. Compromised plumbing systems from these leaks also mean lower water pressure and more damage. You have to find and fix these leaks fast before they get worse.
Identifying Slab Leaks
Recognising slab leaks early can prevent significant damage and expensive repairs for homeowners. Signs of these leaks can be obvious or subtle. Visible evidence includes damp spots, pooling water on the floor, or cracks in your walls and floors. Less obvious signs are unexpected increases in your water bills, the sound of running water when all taps are off, and a decrease in water pressure.
Promptly detecting these symptoms allows you to address slab leak issues before they worsen quickly.
Visible Signs of Slab Leaks
The first signs of slab leaks are signs that there's an issue. Look for:
Moist spots on flooring materials
A musty smell
Unexplained wet spots or areas on the carpet that look darker than usual
Mould or mildew growing near the base of a structure
This usually means water damage from excess moisture from a leak in the slab.
More signs of a slab leak:
Brown stains on floors, walls or ceilings indicate water coming into concrete structures
Warped or raised floor sections
Areas warm to the touch underfoot mean hot water pipes leak beneath the surface.
Standing water inside or outside your home
-Cracks in flooring and concrete
This means leakage is happening under the solid foundation (slab).
Hidden Indicators of Slab Leaks
You may not see slab leaks, but they are just as important to spot. An unexpected increase in your water bill is a red flag. Water flowing when all taps are closed means a leak is out of sight under the slab.
Visible signs you may have a slab leak:
The hot water heater is constantly running, which means a leak is refilling continuously
Low pressure in household water outlets like showers and sinks
Musty smells from mould or mildew growth due to hidden moisture
Don't wait to spot these hidden signs. Otherwise, you'll have big problems like flooding, mould growth and structural damage.
Tools and Techniques for Slab Leak Detection
Modern methods for detecting slab leaks use advanced tools to find leaks quickly and accurately. The equipment includes:
Thermal imaging cameras
Acoustic detectors
Moisture meters (hygrometers)
Tracer gas techniques
Each of these technologies offers unique advantages in identifying leak sources while minimising damage to your property.
Knowing how these tools work can significantly help homeowners and experts trace the root cause of various leaks, including those from a leaking faucet.
Thermal Imaging
Thermal imaging is a non-invasive method that uses infrared technology to detect temperature anomalies indicating leaks. Thermal imaging cameras capture infrared radiation and convert it to visual images, displaying temperature differences. This technique can locate leaks in walls, ceilings, and floors by identifying temperature changes caused by water leaks. Thermal imagers are used in slab leak detection to generate thermal images that highlight temperature disparities.
The use of thermal imaging cameras is particularly beneficial because it allows for:
the detection of hidden leaks under slabs without the need for destructive testing
identifying areas where the temperature is different from the surrounding environment
locating leaks that might otherwise go unnoticed
Acoustic Listening Devices
Another way to find slab leaks is with acoustic listening devices. By boosting the leaking water sounds, these tools help pinpoint the exact spot of the leak so you can fix it fast.
Equipment like acoustic listening devices are designed to reduce background noise and boost the signal of leaks on various surfaces. This technology allows professionals to hear the faint sound of water from pipes even when other methods won't work.
Moisture Meters and Tracer Gas
Tracer gas methods using hydrogen are essential to slab leak detection. They can find tiny leaks in pipes underground or behind walls. They inject hydrogen into the piping system and then use detectors to sense any hydrogen escaping into the air, pinpointing the exact location of the leak.
Moisture meters are also crucial in detecting leaks in concrete slabs. These instruments measure the moisture on the surface of the concrete, which could mean a slab leak. By measuring fluctuations in moisture content, they help experts locate where more water accumulates due to hidden leaks. With tracer gases like hydrogen, these tools are essential for efficiently finding leaks under concrete slabs.

Take measures after repairs to ensure durability.
Start by cutting off the water flow and deactivating nearby electricity or gas services as a precaution. Begin assessing the damage, choose an effective repair method, and finish with strategies to secure long-lasting results. This process ensures successful and durable remediation of slab leaks.
Assessing the Damage
First things first, you need to assess the extent of the damage. Look for:
Cracks in the foundation could be water-induced and related to the leak.
Hairline and more significant cracks to see how bad it is.
Mould or mildew on your floors or walls means there's too much moisture coming from the leak.
Puddles on your floor, especially around the bottom of your home, mean you have a slab leak.
You may also notice your floors are uneven, as the foundation moved due to the slab leak. Finding these signs is essential to determine the size of the problem and guide the repair. Do a thorough inspection to identify all the affected areas and manage them during the repair.
Repair Methods
There are different ways to fix slab leaks, each specific to the situation. Pipe rerouting is a standard method that involves:
Diverting water flow around the damaged pipe section and away from the foundation
Shutting off the damaged pipeline
Running new pipes through walls and ceilings
This method is most helpful when you can't access the damaged pipe directly.
Epoxy inside the pipes is another way to seal off leaks with minimal digging. This minimises excavation and disruption and is more cost-effective.
If neither rerouting nor epoxy inside the pipes can fix a broken pipe under the slab, then replacing that section will be required. That means digging around, removing, and replacing.
Post-Repair Considerations
Once done, here are a few things to do to ensure the repair is successful and the system is protected for the long haul.
Do a full pressure test to detect missed leaks and verify the system works.
Watch for new leaks to catch any issues early.
Do regular inspections and maintenance to prevent further damage and costly repairs.
