What multi-storey membrane failures actually teach you about longevity: pulled from a live project, not a lab.
Waterproofing failures usually start small
A waterproofing failure rarely begins with the major leak that eventually gets noticed. It can start with poor substrate preparation, an incorrectly detailed penetration, a weak termination or a small area where the membrane system has been compromised.
On a multi-storey building, those details matter because water can travel before it becomes visible, making the source of a leak far more difficult to identify.
A membrane is only one part of the system
Effective structural waterproofing depends on the entire installation. The membrane needs to work with the substrate, joints, corners, outlets, penetrations, upstands and adjoining building elements.
This is why the correct product alone cannot guarantee longevity. Specification, preparation, detailing and installation all contribute to the final performance of the system.
What live projects teach us
Real site conditions expose the challenges that technical data sheets cannot fully replicate. Different substrates, changing weather, programme pressure and multiple installation teams can all affect the finished result.
Training helps applicators understand not only how a waterproofing product should be installed, but why each stage matters. That knowledge makes it easier to identify potential problems before the membrane is covered and remedial work becomes costly.
Technical support should reach the site
Protech supplies structural waterproofing systems for a range of substrates, loads and exposure conditions, supported by technical specification and site-level input where required.
For contractors, developers and specifiers, getting the waterproofing detail right before installation is considerably easier than investigating a failure afterwards.
