Use this record for
Internal wet-area waterproofing repair and recheck records where the project has defined a repair disposition and retained system compatibility. Tracks defect location, source evidence, approved instruction, repair materials and actual application, cure evidence as instructed, independent recheck and closure.
Outside this record: Diagnosing structural movement or the cause of water ingress, designing a repair, approving substitutions, specifying product compatibility or cure values, certifying waterproofing, or authorizing concealment. Roofs, facades, tanks, below-ground work, pools and other specialist systems need a separate project-specific record.
Blank record. A project-authorized person supplies the repair disposition and acceptance criteria, checked against the exact compatible system and current local instructions. Actual repair, cure evidence, recheck result, dates and signatures remain blank until performed. Installer self-check, independent inspection and formal release are separate records.
Collect these project inputs first
- Original defect and affected work extent
- Map the actual room, detail, product/batch, installation history and source record; do not infer cause from appearance alone.
- Authorized written repair disposition
- The responsible designer/project authority states approved repair materials, method, extent, acceptance and any required review.
- Compatible current system documents
- Exact membrane/accessory manufacturer instructions and approved project submittal control compatibility, preparation and any cure/recoat requirements.
- Recheck and test requirement
- Specify what must be reinspected, who performs it and whether any separately authorized project test/retest is needed; no universal test is assumed.
- Closure and release authority
- Identify installer, verifier, certifier only if appointed, contractual release role and actual notice obligations.
How to use the checklist
- Create one traceable entry per defect or linked repair location. Map room/zone, drawing/photo, affected detail and original inspection or test record.
- Hold the affected work until an authorized written disposition identifies the repair scope, compatible system and required evidence. Do not substitute products or create cure values on this form.
- Record actual surface preparation, product/batch, person, date/time, conditions, application evidence and any system-defined cure/recoat records against the instruction.
- Reinspect the same mapped area after the instruction’s stated conditions are met; record findings, photos, result and any new issue. A test/retest is entered only if separately specified and authorized.
- Keep installer completion, independent verifier findings and formal project/certifier release attributed to the person and authority that actually acted.
Checks and the records they need

When a check cannot be closed
| Situation | What to record or resolve |
|---|---|
| No written disposition identifies the repair and acceptance basis. | Keep the issue open and obtain direction from the responsible designer/project authority before repair. |
| Proposed repair product or accessory is outside the approved system or compatibility is unclear. | Hold and obtain documented compatibility and project approval; do not assume similar products are interchangeable. |
| Repair cure/recoat window, environmental limits or test requirement are not stated. | Use the exact current approved system and project instruction; request written clarification where they conflict or are incomplete. |
| Repair looks complete but no separate recheck or release is documented. | Record installer completion only; leave verification and formal release Pending until their assigned authority records the actual decision. |
Repair / recheck status
Mark complete only when the authorized instruction, actual repair evidence, any required recheck and separate release decision are linked. Installer completion alone does not certify or release the area.
Repair closure status options in the blank record:
- Repair rechecked — formal release evidenced
- Hold — further repair or recheck required
- Disposition / verifier / release pending
Record the assigned roles: Repair installer / role / date; Independent/site verifier / role / date; Certifier only if appointed/required / reference; Contract release authority / decision reference.
Teaching example — mapped repair and recheck
Fictional teaching example only. These are illustrative document references, not a real project, engineering values or completed inspection results.
Fictional training prompt only. Room B-02, photo TRAINING-WP-01 and instruction REP-EXAMPLE Rev B are invented identifiers; no work or result is represented as completed.
- Requirement to carry into the record
- The fictional instruction identifies a wall/floor junction repair and calls for reinspection against the actual approved system documents. It supplies no product, cure time, test requirement or pass result.
- Illustrative reference
- Illustrative only: REP-EXAMPLE Rev B; actual project disposition and current TDS must replace it.
- What the site record should capture
- Can the original defect and repair be found on the room plan? Which authority issued the repair instruction? Which actual product/batch and method were used? What separate recheck and release evidence closes it?
