## Summary

Check falls, loose paving and trapped drainage routes before covering the surface. Adjustable supports or packing need appropriate design; a new deck should not conceal an unresolved water or settlement problem.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.
