Waterproofing Inspection Checklist

Use this Waterproofing Inspection Checklist to verify proper sealing, detect leaks, and ensure structures meet waterproofing standards during construction.

1. Are roof or deck drains clear, functional, and positioned at the lowest drainage points?

2. Is there any evidence of ponding or inadequate drainage after testing or rainfall?

3. Is a drainage mat or system installed in areas requiring enhanced drainage (e.g., green roofs)?

4. Are scuppers, gutters, and downpipes properly integrated into the waterproofing design and functioning?

1. Has a flood test or water spray test been completed to identify leaks or weak points?

2. Are there visible signs of membrane displacement, blistering, or damage?

3. Have all punch list items and deficiencies been corrected before the final inspection?

4. Is photographic or written documentation available for quality assurance and compliance records?

5. Has the installer provided warranty information and long-term maintenance guidelines?

1. Is a regular maintenance plan in place to inspect waterproofed areas?

2. Are rooftop and exposed membranes kept clear of heavy equipment, plant growth, and foot traffic?

3. Are minor damages promptly repaired using compatible materials?

4. Have building occupants been informed on how to avoid damaging the waterproofing system?

5. Are follow-up inspections scheduled and documented at key intervals (e.g., 6 months, 1 year)?

1. Has a site inspection been conducted to assess moisture risks and vulnerable areas?

2. Are all surfaces clean, dry, and free of debris, oil, or contaminants before waterproofing begins?

3. Has the surface been tested for compatibility with the waterproofing materials?

4. Are substrate cracks and joints properly treated or repaired before membrane application?

5. Is the slope adequate to direct water flow away from the structure?

1. Are materials approved and compliant with relevant building codes or manufacturer standards?

2. Is the waterproofing product within its expiration date and stored under appropriate conditions?

3. Has the manufacturer’s technical data sheet been reviewed and followed during application?

4. Are all accessories (primers, sealants, tapes) compatible with the main waterproofing system?

1. Is the membrane applied uniformly and at the correct thickness according to specifications?

2. Are overlaps and joints properly sealed and within the specified tolerance limits?

3. Are corners, pipe penetrations, drains, and upturns correctly reinforced and sealed?

4. Is the recommended curing time observed before covering or exposing the membrane to loads?

5. Has the membrane been protected from physical damage during ongoing construction?

1. Are all flashing installations watertight, well-integrated, and securely fastened?

2. Are expansion joints waterproofed using flexible, compatible materials?

3. Are sealants applied correctly—well-tooled, continuous, and free of bubbles or voids?

4. Are membrane terminations sealed properly and mechanically fastened where required?
