Leak (HVELD) Detection
High Voltage Electronic Leak Detection (HVELD) is a method of detecting breaches in waterproofing membranes and coatings. HVELD testing is performed using a high voltage current on a dry horizontal or vertical surface. A current is generated that will pass through a non-conductive material, such as a waterproof membrane, and should a breach be present, it forms a circuit sounding an alarm on the testing unit and pinpointing the exact location of the breach.
Advantages of HVELD testing:
- detecting holes in membranes and coatings that are not visible to the eye
- non-destructive
- good for very small areas and difficult to reach areas or areas where flood testing is not possible
- locates defects precisely and enables immediate repair
- able to re-test repairs immediately, depending on the type of membrane
- less expensive and less time consuming than conventional flood testing
- eliminates the hazard of overloading structural decks during flood testing.
We can locate leaks on the following horizontal and vertical surfaces:
- Torch-On Membrane systems
- Liquid Applied Systems, such as acrylics and polyurethanes
- Bituminous coatings
- PVC membranes
- TPO membranes
- Butynol
- all other non-conductive membranes and coatings.
Contact Waterseal for:
- leak detection on new or existing membranes
- ITP compliance testing on new membranes
- an assessment of the condition of existing membranes for dilapidation reports and building inspections.
*Disclaimer: The nature of some membranes and/or substrates can make them unsuitable for HVELD testing. Please contact Waterseal for further information.
Basements and Undercroft
Correct waterproofing to the below grade elements of a building is critical to ensure that the structure maintains its integrity and liveability. Although best addressed at the time of construction, Waterseal Waterproofing can provide solutions for persistent damp or flooding in new or existing buildings.
Roof Gardens & Planter Boxes
With the growing interest in sustainable homes and buildings, the inclusion of suspended planters and roof gardens in contemporary designs has focused attention on the importance of qualified Green Roof waterproofing specialists. Waterseal Waterproofing will provide you with industry leading advice on the best waterproofing and drainage system to suit your project and budget.
Retaining Walls
Retaining walls can be external walls forming part of the landscape design, or walls that form part of a property. Landscape walls are less critical but still require an appropriate waterproofing system to prevent dampness from the ground spoiling the aesthetic nature of the design. Whether insitu, block or piled retaining walls, Waterseal Waterproofing can install the system to best protect your structure and keep your project moving.
Roofs (New & remedial)
One of the many reasons concrete is commonly used as the roofing element in commercial buildings is for its durability, but as hardy as it is, cracks can and do occur leading to water ingress. This can have a devastating impact on the longevity of the slab and on the quality of life for the building’s occupants. Waterseal Waterproofing understand the many and varied waterproofing systems on the market and our team is skilled in the application of PVC, Polyurethane, Acrylic, TPO, Butynol and Torch Applied Modified Bitumen Membranes, meaning no matter what the situation or type of substrate, Waterseal Waterproofing will meet expections, every time.
Car Parks
From renovating of existing surfaces to application of new coatings, Waterseal Waterproofing partner with market leading manufacturers to supply and install waterproof coatings that not only look good but deliver unparallelled performance in even the most demanding of situations.
Water Retention and Fire Tanks
Water containment tanks are a key element in all commercial fire protection systems and place performance demands on the waterproof coating like nothing else. Waterseal Waterproofing are specialists in tank waterproofing and will provide you with a system that will deliver years of trouble-free performance.
Balconies, Terraces and Podiums
Balconies, terraces and podium areas which are situated above or partly above occupiable rooms and/or spaces all require their own specific level of protection depending on the nature of the substrate, intended use and finished surface. Waterseal Waterproofing’s team of specialists have years of experience with new and existing buildings and will provide you with the most appropriate system to best suit your needs.
Water Features and Ponds
Water features & ponds can add significantly to the amenity of a home or commercial property but can also lead to an ongoing headache if not waterproofed properly. Correct selection and installation of the waterproofing membrane will ensure you get to enjoy the serenity for years to come.
Lift Pits
Even when constructed at floor level, elevator shafts require excavation below ground level which can leave the lift pit vulnerable to ingress if not waterproofed correctly. Waterseal will advise, supply and place the right membrane and waterbar system to ensure water seepage is never a problem. Whether block or concrete, new builds or retrospective installs, Waterseal Waterproofing will give you peace of mind.
Silicone and Mastic Jointing
Waterseal Waterproofing will expertly install sanitary grade silicone to professionally finish internal and external tile and stone installations in new and existing residential and commercial buildings. In addition, we also supply and install specialist mastic jointing to horizontal and vertical expansion joints in block and pre-cast walls, concrete slabs, pools and water features and to aluminium façade cladding.
Wet Areas
Since 1996, Waterseal Waterproofing have successfully completed over 50,000 Australian Standards and NCC compliant membrane installations to ensuites, bathrooms, laundries, powder rooms and W/Cs across Perth and surrounding areas. In conjunction with Calmarc Chemicals, Waterseal Waterproofing use Australia’s only manufacturer-approved single-coat Class III waterproof membrane. Proven by CSIRO testing to be effective at 500 microns, this high-solids, no-slump coating has revolutionised internal undertile waterproofing and has done away with the need for time consuming second coats. Unlike polyurethanes, this product is fully compatible with cement-based adhesives and guaranteed to never be the cause of drumminess when used under tiles.
In addition to liquid membranes, we also use undertile butynol, anti-fracture and sound-reducing waterproof sheet membranes to provide certainty in vulnerable ‘frame’ builds and to save you time at the back end of the job when time really matters.
Whether single or multi-level dwellings, stud frame or concrete masonry, Waterseal Waterproofing have the knowledge and expertise to advise and install the best membrane system in new or existing builds.
Plant Rooms and Service Decks
Plant areas are generally bunded to contain leaks or spillage from equipment, however cracks to the substrate due to shrinkage, thermal expansion/contraction or even vibration from installed plant can allow water to enter the slab causing corrosion to reinforcement and possibly escaping into spaces below. Correct membrane selection and installation is of critical importance to ensure long term protection of the structure and installed equipment. Waterseal Waterproofing partner with the world’s leading manufacturers of PVC, Polyurethane, Acrylic, TPO, Butynol and Torch Applied Modified Bitumen Membranes to provide you and your client with certainty now and into the future.
