Our Consultants are able to assist at various points within the lifecycle of an installed membrane, assisting in identifying breach locations within installed membrane systems.
Our main focus is on performing the role of a quality control technician during the installation process, we can perform a range of duties including observing and reporting on the technical aspects of a membrane installation and its conformance or deviation from the project specification. We are also well equiped to provide post installation compliance testing via Electronic Leak Detection techniques utilising the Detec Integriscan test equipment.
Detec Integriscan
This Electronic Leak Detection (ELD) method establishes a voltage potential between the membrane and the roof deck and then track any leakage current. This is accomplished by wetting the surface of the membrane, applying a voltage with respect to ground and then locating areas where electrical current flows through membrane breaches to the deck. A scanning platform is used to test the membrane for breaches. The platform is constructed with dual metal sweeps which make continuous electrical contact with the membrane surface. The outer sweep forms a continuous perimeter around the platform with the inner sweep contained within the perimeter of the outer sweep.The Vertical Scanning Unit (VSU Roller) can be used on horizontals, details, transitions and is the only reliable low voltage testing method for vertical surfaces. Both units comply with ASTM Practice D8231-19 and D7877- 14.

Additional Scanning capabilities include:
The Tramex RWS Roof and Wall Scanner is a multi-mode non-invasive impedance scanner designed for the instant, precise and non-destructive evaluation of moisture conditions and leak tracing in roofing per ASTM D7954 and in wall systems of the building envelope. Integrity-test utilise the RWS to evaluate the extent of the moisture problem and help trace and pin-point its source.
Our Tramex CMEX5 unit assist both during installation phase compliance testing and during investigation phases, performing the following functions:
The ultrasonic pulse-echo technique of ultrasonic gauges measures the thickness of coatings on nonmetal substrates (concrete, plastic, wood, etc.) without damaging the coating. The instrument probe contains an ultrasonic transducer that sends a pulse through the coating. The pulse is reflected back from the substrate to the transducer, which converts it into a high-frequency electrical signal. The echo wave form is analyzed to determine coating thickness. These gauges accurately measure the dry film thickness of organic coatings on concrete, wood, and wallboard substrates. Integri-test utilize the DeFelsko Positector Ultrasonic dry film thickness gauge, our advanced body unit used in conjunction with the 200 probe measures up to 3 individual layer thicknesses in a multi-layer system and features a graphic readout for detailed analysis of the coating system .
Adhesion is an important physical property of any applied bonded membrane or protective coating, significantly contributing to the performance of the installed system when exposed to harsh operating conditions.
Our technicians focus on providing adhesion testing services that meet your project's needs. We carry out adhesion testing of membranes and coatings to help you meet the requirements of Australian Standards and manufacturer specifications to evaluate the substrate prior to application, the performance of coatings upon application or of those that have been in service for extended periods and may require maintenance.
