Inspection and Test Plan for Method Statement: Mosaic Tile Installation in Wet Areas and Feature Walls

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 20 Aug 2026 Rev. 00 2 views
About this ITP: This ITP defines hold and witness points for mosaic tile works in wet areas and feature walls, ensuring measurable quality from substrate to final finish.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To verify each critical stage of mosaic tile installation meets specified standards, preventing rework and ensuring durability in wet conditions.

Who uses this inspection and test plan

QA/QC engineers, site engineers, tiling supervisors, waterproofing specialists, and Client/Engineer representatives.

When this ITP is prepared and submitted

From material receipt through substrate acceptance, waterproofing, flood testing, installation, grouting, and final handover.

Who receives or approves this ITP

Client/Engineer for review and approval before starting works.

Inspection scope

Covers materials, substrate flatness/plumb/moisture, waterproofing DFT and integrity, flood tests, adhesive mixing and coverage, alignment, movement joints, grouting, and final acceptance.

Typical hold, witness, and review points

Hold: Substrate acceptance, waterproofing/DFT, flood test, pre-grout, final. Witness: Materials, adhesive mixing, installation checks, movement joints, grouting.

Typical inspection records

MIRs, checklists, WFT/DFT logs, flood test reports, IR/ITR forms, photos, approvals, NCR/CAR if any.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Material verification (tiles, adhesives, grouts, trims) Review approvals, batch numbers, COA/COC, TDS/SDS Approved submittals; valid shelf life; compliance with BS EN 14411/12004/13888 QA/QC (Contractor) / Client Rep. (Witness) MIR, approvals, photos
Substrate acceptance (plumb, flatness, moisture) 2 m straightedge, feeler gauges, moisture meter Deviation ≤ 2 mm/2 m; ≤ 1 mm/300 mm; moisture within adhesive limits Site Engineer / QA/QC (Hold) / Client Rep. (Hold) Substrate checklist, IR approval
Waterproofing membrane application WFT/DFT gauge measurements; detail checks DFT within TDS (typ. 1.2–1.5 mm total) [Verify]; full coverage; no pinholes Waterproofing Specialist / QA/QC (Hold) / Client Rep. (Witness) Membrane ITR, WFT/DFT logs, IR
Flood test (wet rooms) 24 h water test No visible leaks; water level drop ≤ 3 mm/24 h (evaporation only) [Verify] Site Engineer / Client Rep. (Hold) Flood test report, photos, IR
Set-out and mock-up approval Visual and measurement Balanced layout; approved mock-up; trims and colors confirmed Tiling Engineer / QA/QC (Hold) / Client Rep. (Witness) Mock-up approval, set-out records
Adhesive mixing and open-time control Review mix ratio, timing, temperature, pot life Per TDS; no retempering after slake; used within pot life Foreman / QA/QC (Witness) In-process checklist
Mosaic installation alignment and coverage Pull-checks each ~10 m² or 20 sheets; alignment, joint width, lippage checks Coverage ≥ 95%; sheet offset ≤ 1 mm; joint width ±0.5 mm; lippage ≤ 0.5 mm Foreman / QA/QC (Witness) Coverage logs, photos, checklist
Movement joints and trims Dimensional checks; sealant TDS verification Joint locations per design; sealant ASTM C920/EN 15651; neat finish Foreman / QA/QC (Witness) Inspection record, photos
Pre-grout inspection Visual; joint depth/cleanliness; alignment reconfirmation Joints ≥ 2/3 depth; surfaces clean; alignment OK; defects rectified QA/QC (Hold) / Client Rep. (Hold) IR approval
Grouting and cleaning Mix ratio/pot life; haze removal timing Full, uniform joints; no pinholes; surface clean; epoxy cleaning per TDS Foreman / QA/QC (Witness) Checklist, photos
Final inspection and acceptance Visual under uniform lighting; straightedge; tap-test (if specified) Meets all acceptance criteria; documentation complete; protection in place QA/QC (Hold) / Client Rep. (Hold) ITR/IR, handover records

Frequently asked questions

Perform at least one pull-check per approximately 10 m² or every 20 sheets and at starts/returns. Increase frequency in high-risk or complex areas.

Any visible leakage or water level drop beyond allowable evaporation without another identified cause is a fail. Investigate, repair membrane, and retest.

No. Pre-grout inspection is a hold point to confirm alignment, joint cleanliness, and rectification of defects before irreversible grouting.
