Technical analysis
Field inspection of laps, openings, penetrations, terminations, repairs and concealed-work records.
Engineering scope
- Principle
- Inspect the substrate before installation and define the sequence of field membrane and accessories.
- Verification
- Acceptance should cover continuity, drainage direction, adhesion, restraint, damage and later-trade interference.
- Field control
- Photograph each elevation or roof zone before it is concealed and record all repairs.
System decision
Start with the actual roof or wall build-up, climate, indoor condition and risk at the relevant interface. Product data must be connected to a defined layer and detail.
Documentation and acceptance
Keep design details, approved product data, delivery labels, batch records, mock-ups, concealed-work photographs and repairs traceable to the installed area.
