Documenting the Wall Substrate Before Guard Fixing
A substrate record captures what lies behind the finished wall before the guard hides it. It gives installers and maintenance teams evidence of reinforcement, services and the accepted fixing zone.

Selection considerations
Photograph each relevant wall section before closure or before the protection assembly is fitted. Include a location reference and a scale where necessary. Connect the photographs to the wall drawing so a future team can tell which backing belongs to which corridor.
Record changes in wall construction and any areas where the specified attachment cannot be achieved. The partition contractor should confirm the provided reinforcement while the protection supplier confirms the required mounting arrangement. Avoid substituting a generic anchor based only on the front-face appearance of the wall.
Keep the accepted substrate inspection with the installed product code and drawing revision. If a rail or guard is later moved, the old record should not be treated as proof of the new mounting zone. Review concealed services and the revised attachment detail before drilling or refixing.
Before you specify or order
- Photograph backing before concealment
- Link evidence to wall locations
- Record construction changes
- Review new fixing zones separately

Common question
Does a photograph prove fixing capacity?
No. It documents visible construction; the attachment design and required supporting evidence remain separate.
