Waterproofing QA/QC: How to Prove the System Was Installed Correctly
Waterproofing failures become difficult to investigate after finishes cover the system. Quality control must therefore create evidence during execution.
Coverage looks complete but dry film is too thin.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Coverage looks complete but dry film is too thin.
Review area, material consumption, wet-film readings and substrate roughness.
Uneven application or underestimated consumption can leave thin spots.
Apply compatible corrective coat after checking recoat window and substrate condition.
Use batch and area logs, calibrated gauges and hold points for each coat.
Measure film thickness by approved method and record repairs before concealment.
Visual colour uniformity is not proof of specified thickness.
