About Waterproofing Integrity

Waterproofing Integrity was established in 2019 in Sydney, New South Wales out of a need for greater quality control and compliance in the installation of waterproofing applications. Since then, Waterproofing Integrity has grown to provide compliance consultation and onsite testing services, such as electronic leak detection and membrane thickness testing, on new construction projects and in existing building assets.

We work with builders, waterproofing contractors, material suppliers and manufacturers and other industry professionals to mitigate breaches and insufficient application that can lead to costly building defects.
