## Summary

Resolve levels and foundations before deciding board direction. Step changes, soil movement and runoff can govern the project more than the walking surface; avoid using unsupported packing to compensate for slope.

## 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.

Runoff direction | Obtain applicable product or design evidence
Step transitions | Assign installation and maintenance responsibility

## WPC terraces on sloping sites — 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. Foundation levels; Runoff direction; Step transitions
