Adhesion Testing .png

Ensuring the bond of a waterproofing membrane to a substrate can play an important consideration in the overall performance of the waterproofing application. Adhesion testing is a destructive test most commonly applied on exposed areas such as rooftops and podiums.


Some builders that Waterproofing Integrity deal with otherwise prefer to have adhesion testing on a sample of internal wet areas (bathrooms, laundries) and balconies on lower levels of multi-storey construction projects to ensure the waterproofing membrane is achieving a bond to the concrete before proceeding to upper levels.

Adhesion testing is a destructive test method conducted using aluminium dollies connected to a hydraulic pump to discern the bond strength that a membrane has to the substrate.  Membranes that are designed to be fully bonded to their will exhibit reduced performance where a sufficient bond is not present.  An exposed membrane that has de-laminated from its substrate can be more easily cut torn when force is applied.

Waterproofing Integrity technicians use calibrated Positest AT-M hydraulic pump on waterproof coatings in accordance with ASTM D7234 - 12 - Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers.
