## Summary

Distinguish occasional inundation from normal outdoor wetting. Floodwater can introduce uplift, debris and contamination; recovery and inspection procedures need project-specific engineering rather than an assumption that moisture-resistant boards solve flooding.

## 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.

## Key points

Flood load assessment
Debris exposure
Recovery inspection

## Comparison

Design check | Evidence to record
Flood load assessment | Show the requirement on the project drawing
Debris exposure | Obtain applicable product or design evidence
Recovery inspection | Assign installation and maintenance responsibility

## WPC decking in flood-prone areas — What should be confirmed before ordering?

Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation. Flood load assessment; Debris exposure; Recovery inspection
