Question 1

What is the difference between closed-water and spray-test witnessing?

Accepted Answer

Closed-water witnessing observes overall water-resistance and leakage behavior at agreed water-level, direction, and duration conditions. Spray testing examines specified joints or interfaces under agreed spray conditions; it does not by itself establish static-water performance at a comparable height.

Question 2

Does flood barrier inspection replace product certification or statutory acceptance?

Accepted Answer

No. The service documents the inspected installation and agreed witnessing conditions. It does not replace product certification, structural design sign-off, or statutory acceptance.
