What is leak detection?

Leak detection refers to the process of identifying the presence or location of a leak in a system or structure, such as a water or gas pipe, a fuel tank, or an oil well. The methods used for leak detection can range from simple visual inspections to sophisticated electronic sensors and techniques, such as acoustic or infrared imaging. The goal of leak detection is to prevent or minimize damage, waste, and environmental harm, and to maintain the efficiency and safety of the system or structure.

The three basic functions are:

  1. determining if there is leakage or not,

  2. measurement of leak rate,

  3. leakage location

  • There are many methods and types of test equipment used for leak detection, however there is no single technique that fits every situation. Some of the methods and tools include: Acoustic, Tracer Gas, Thermal Imaging, Moisture Mapping, evidence based water testing etc. In Australia there is no formal license, training, courses or apprenticeships in leak detection nor does it have its own industry category. It is therefore an acquired skill.

  • Leak detection can be 100% accurate depending on the experience and skill of the technician. Utilizing advanced tools and equipment, leak detection is non invasive in the majority of applications.

  • The average cost for leak detection is between $200.- and $600.- depending on the scope of works. For example, a roof or wall leak of a commercial factory may require more time, boom or scissor lifts, an additional technician and OH&S requirements. A residential burst pipe can take less than 30 minutes to locate.

    • Active - When a pressure barrier (pipe) fails to contain or isolate a system fluid (water or gas) which is a result of cracks, gaps or permeation between sealing surfaces.

    • Non Active - When an surface/construction designed to isolate dry from wet is exposed to fluid (rain, wet areas when used - bathroom, laundry & kitchen), fails to contain the ingress.

Water Leaks:

  • It's easy to locate a leaking tap or toilet, but hidden leaks are difficult to see. Has your water bill unexpectedly gone up even though you haven't changed your usage or behaviours in your home? Have you noticed wet patches on your lawn or water damage in your house? You may have a leak.

  • Turn off all taps and isolate water supply to toilets, dishwasher, washing machine, hot water service and irrigation .

    1. Locate your water meter. It's usually at the front of your property.

    2. Write down or take a picture of the numbers on the water meter dials. On most meters, the last two dials are red.

    3. Don’t use any water for the one hour.

    4. Check if the last two numbers on the dial have changed. If they do, you have water a leak. The greater the change, the bigger the potential leak.

  • Check your hot water system's Expansion Control Valve (ECV) or (TPR) Valve which is used to control the increase in pressure caused by hot water.

    • Check your taps and toilets regularly for leaks.

    • Add a small amount of food colouring in your toilet cistern and check the bowl. Toilet cisterns shouldn't release any water between flushes.

    • Disconnect hoses or irrigation pipes that are always connected to garden taps. Then check the taps aren't leaking.

    • Look for green patches of grass that are different from the surrounding grass. This can mean you have an underground pipe leak.

    If you suspect there's a leak, we recommend call a leak detection expert with specialist equipment.

Shower Leaks:

    1. Damp Musty Smell.

    2. Tile grout is calcifying.

    3. Drummy tiles.

    4. Paint Peeling, swelling door jambs and architraves.

    5. Mould and Mildew.

    6. Mouldy silicon that can’t be cleaned.

    7. Water on the Bathroom Floor.

  • Yes anywhere where water is used whether its in the shower, laundry, kitchen etc. Cement based grout is porous, most silicon products have a limited life span of 3-5 years. Tap penetrations, fixtures and shower screens are also a common source of water ingress. Most wet areas constructed prior to 2010 have no water proofing. These buildings are at high risk of severe water damage to structural framing, plaster, timbers and cause concrete cancer.

  • They use non-invasive methods like thermal imaging and moisture meters to accurately locate the source of the leak.

  • No, the methods used are non-invasive, meaning there is no need for drilling or breaking into walls unless absolutely necessary.

  • It's best to contact leak detection professional to ensure the leak is properly identified and repaired.

  • Yes, they offer repair services after detecting the leak to resolve the issue completely.

Roof Leaks:

  • Signs of a leaking roof can vary from obvious to subtle. Some tell-tale signs include water stains on the ceiling or walls, dripping water pooling on the floor, water spots on exterior walls, and missing or damaged shingles. These symptoms may indicate a potential roof leak that needs immediate attention.

  • There are several common reasons for a leaking roof. It could be due to clogged gutters, missing or cracked shingles, damaged flashing around the chimney, roof vent issues, leaking skylights, or punctured roof valleys. Additionally, improperly installed roof membrane or sarking and an aging roof with deteriorating materials can also lead to leaks.

  • If you notice a roof leak, take immediate action to prevent further damage. Safeguard your belongings by moving them away from the leak and using buckets to catch dripping water. Soak up as much water as possible and use fans to dry the area. However, remember that these are temporary fixes, and you should seek professional help to address the root cause.

  • Yes, it's essential to call a professional roofing company to perform roof leak repair. While temporary fixes can manage the situation for a while, roof leaks can reoccur and cause significant damage if not properly addressed. A professional roofer can assess the issue, ensure proper installation of roof materials, apply sealants, and use high-quality waterproofing products for a lasting solution.

  • The cost of roof leak repair depends on the extent of damage and the necessary repairs, replacements, and sealants. Standard homeowner's insurance policies usually cover water damage and roof leaks, except when negligence is involved. It's best to contact your insurance company to confirm coverage for the damage.

    Dealing with a roof leak promptly is crucial to protect your home from further damage. Don't hesitate to reach out to a licensed and experienced roofing professional to ensure a comprehensive and lasting solution for your leaking roof. Remember, timely action can save you from costly repairs in the long run.

Building Leaks

Slab Heave

  1. What is slab heave? Slab heave occurs when the concrete slab under a building moves unevenly due to changes in the moisture content of the soil beneath, often causing structural damage.

  2. What causes slab heave? It's mainly caused by reactive clay soils that swell when they absorb moisture from excessive rain, leaking pipes, or poor water management around the building foundation.

  3. What are the signs of slab heave? Look for uneven floors, cracks in walls, doors, or windows that stick, and gaps between walls and floors.

  4. How can slab heave be remedied? Remediation might include underpinning, using resistance piers, chemical injection to stabilize the soil, or improving water drainage around the property.

Rising Damp

  1. What is rising damp? Rising damp is moisture moving up from the ground into the walls of a building, usually because of a failed or absent damp-proof course (DPC).

  2. How can you identify rising damp? Indicators include tide marks on walls, peeling wallpaper, damp smells, and salt deposits on the walls.

  3. What causes rising damp? It can be caused by a failed damp-proof course, bridging due to high external ground levels, or internal finishes blocking the DPC.

  4. How is rising damp treated? Treatments include installing a new DPC, damp-proofing with injection creams, and possibly re-plastering affected areas to manage salt damage.

Efflorescence

  1. What is efflorescence? Efflorescence is a white powdery deposit of salts that forms on surfaces like concrete and brick, usually visible after water evaporation leaves salt residues behind.

  2. What causes efflorescence? It's caused by water moving through a wall or floor carrying salts to the surface. Often, this is related to water ingress from faulty or insufficient waterproofing.

  3. How can efflorescence be prevented? Preventative measures include using water repellent materials, proper installation of vapor barriers, and ensuring good drainage around structures.

  4. What are the best methods to remove efflorescence? It can often be brushed off dry surfaces; for persistent cases, use a dilute acid solution or specialized cleaning products designed for efflorescence removal, but always test on a small area first.
