Independent Quality Assurance

Installation monitoring focuses on observing workmanship during membrane application. Quality assurance is broader—it covers design review, material verification, installer competency checks, installation monitoring, integrity testing, and final certification. QA provides systematic verification across the entire project lifecycle, not just the installation phase.

Ideally, QA begins at design stage. Early involvement allows us to review specifications, identify potential risks, and ensure the proposed system is appropriate for site conditions. Starting QA before installation begins prevents problems rather than discovering them later when rectification is expensive.

Yes. We regularly provide independent QA for waterproofing systems designed by others. We review the original design documentation, assess compliance with BS8102, and verify that materials and installation meet the specified requirements. Our independence ensures objective assessment regardless of design origin.

Testing methods depend on system type and project requirements. We use flood testing for horizontal surfaces, electronic leak detection (including pulse vector mapping) for membrane integrity verification, pressure decay testing for cavity systems, and visual inspection with moisture meters for accessible areas. All testing is conducted to relevant British Standards.

QA catches problems early when they're less experience to fix. It verifies that materials, installation, and testing meet specifications, reducing the risk of post-completion failures. Documented QA also protects you legally by demonstrating that proper oversight was in place, which is crucial if disputes or insurance claims arise.
