Retrofitting entrance mat frames into existing floors
Mat-frame retrofit work starts with a survey of the existing floor, recess and threshold. The new frame should suit the substrate and final level rather than merely match the old outline.

Selection considerations
Check edge damage, concealed services and the availability of space below the finish. Measure door clearance and changes in level around the opening. Establish whether the frame is reused, replaced or requires substrate repair.
Compare the complete new mat-and-frame detail with the available recess. Include preparation, fixing and temporary route protection in the installation scope. If an alternative surface arrangement is proposed, review the transitions explicitly. Keep a record of the final frame dimensions so future mat replacement does not restart from rough site measurements.
Before you specify or order
- Survey existing edges and services
- Confirm door clearance

Common question
Can a new mat be ordered using the old frame's outside dimensions?
