What the waterproofing inspector looks for, and how to be ready for the visit
The reviewer arrives at the museum plaza, but the crew cannot connect its photograph folder to the drain locations. Some details are already covered, and the last report’s open items have no correction references. The team expected the visit to sort out what the review needed.

Prepare for the waterproofing field review by confirming its actual scope and bringing current details, located records and open corrections to the work face. The appointment does not establish one universal inspection checklist or certify everything already hidden. Ask what must remain visible and who can record the required release. Keep coordination, technical assessment and formal approval distinct so the visit produces evidence the next trade can use.
Prepare the work and its record together
- Confirm the review brief. Identify the reviewer’s role, intended areas, relevant project requirements and any required test records. Ask about readiness and notice arrangements before booking instead of assuming every visit has the same scope.
- Bring current detail references. Organize the approved system information around the interfaces being reviewed: drains, joints, penetrations, terminations and transitions where applicable. Flag unresolved details rather than asking the reviewer to infer an approval from a material label.
- Locate supporting evidence. Link substrate checks, installation records and required test results to the drawing location and work stage. Keep missing or unperformed checks visible as open items; an attractive photo collection does not replace required evidence.
- Walk the previous observations. Review the last report with the responsible crew lead. Identify each correction, its location and supporting decision or record. Distinguish a reported completion from a correction the required person has actually reviewed.
- Keep required work accessible. Coordinate visibility, safe access and covering holds through the project’s approved arrangements. Do not remove protection, open work or conceal an unfinished detail merely to make the visit appear complete.
- Track the report after the visit. Assign observations to responsible people and obtain the required clarification or correction decisions. Record which area is released, by whom and with what conditions before advising the following trade to proceed.
Common mistakes
- Treating every reviewer’s visit as the same inspection.
- Submitting photographs without locations or detail references.
- Calling a reported correction accepted before the required review.
Checklist
Ready for the agreed visit
- Review role, scope and areas confirmed.
- Current details and open questions available.
- Evidence located on the plan.
- Previous observations tracked to corrections.
- Visibility, access and covering holds coordinated.
- Release decision recorded by the authorized person.
Check your understanding
The reviewer visited one visible area. Can the covering crew treat that as release of the entire deck?
