Lockfield Holdings Pty Ltd's Integri-test business unit are proud to provide an increased range of services across Victoria . The Integri-test brand provides extended third-party quality control inspection and survey services. 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.
Benefits:-

• Confirms conclusively if a horizontal or vertical membrane is watertight
• Locates breaches during installation so repairs can be made immediately
• Used to test non-conductive membranes in difficult to reach areas, transitions, corners, parapet/wall seams, penetration seals, and vertical surfaces.
• Locates breaches caused by follow on trade damage prior to the placing of overburden
• Provides a safe, precise, cost effective, and conclusive substitute for flood testing
• Delivers quality control through third party verification
• Pinpoints hard to find leaks in older membranes
