Tile Installation Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓18 Inspection Points
✓5 Verification Categories
✓Area Measurement+
  • Room dimensions were measured on site — length and width at floor or wall level as applicable.
  • For wall tiling, each wall was measured separately and door and window openings were deducted.
  • For L-shaped or irregular rooms, the area was split into rectangles and summed.
  • Dimensions were entered in consistent units.
✓Layout Pattern and Wastage+
  • The layout pattern — straight grid, offset/brick-bond, or diagonal — was confirmed before calculating tile quantity.
  • Diagonal (45°) layouts have wastage of 15–20% applied — every perimeter tile is cut and the offcut cannot be reused.
  • Offset or brick-bond layouts have wastage of 12–15% applied.
  • Straight grid layouts in large rectangular rooms have wastage of 10% applied.
  • Small rooms under 5 m² have wastage increased to 15–20% regardless of layout — the perimeter-to-field ratio is high.
  • Large format tiles (600mm or larger) have at least 12–15% wastage for breakage during cutting.
✓Tile Selection+
  • Tile PEI wear rating is appropriate for the location — PEI 1–2 for walls only, PEI 3 for light residential floors, PEI 4–5 for heavy residential and commercial.
  • Anti-slip rating (R-value or wet pendulum) is confirmed for wet area floors — minimum R10 for bathrooms, R11 for outdoor.
  • All tiles were ordered from the same production lot (batch number) — colour and shade vary between lots.
✓Substrate and Preparation+
  • The substrate (floor screed or wall plaster) was checked for flatness — maximum 3mm deviation under a 2m straight-edge for standard tiles.
  • The substrate was clean, dry, and free of dust, oil, paint, or curing compounds before tiling.
  • Wet areas (bathrooms, shower trays) had a waterproofing membrane applied and cured before tiling started.
  • Movement joints were specified at maximum 4.5m in each direction for floor tiling and at all perimeters.
✓Purchase+
  • The quantity including wastage — not the net area — was used for ordering.
Full QC Checklist+

Verify tile quantities, layout, substrate, joints, levels, and installation quality.

✓27 Inspection Points
✓5 Verification Categories
✓Area Measurement+
  • Room dimensions were measured on site — length and width at floor or wall level as applicable.
  • For floor tiling, fixed obstructions (toilet base, bath panel, kitchen island) were measured and entered in Fixed Obstacles Area — not silently left in the gross area.
  • For wall tiling, each wall was measured separately and door and window openings were deducted.
  • For L-shaped or irregular rooms, the area was split into rectangles and summed.
  • Dimensions were entered in consistent units.
✓Layout Pattern and Wastage+
  • The layout pattern — straight grid, offset/brick-bond, or diagonal — was confirmed before calculating tile quantity.
  • Diagonal (45°) layouts have wastage of 15–20% applied — every perimeter tile is cut and the offcut cannot be reused.
  • Offset or brick-bond layouts have wastage of 12–15% applied.
  • Straight grid layouts in large rectangular rooms have wastage of 10% applied.
  • Small rooms under 5 m² have wastage increased to 15–20% regardless of layout — the perimeter-to-field ratio is high.
  • Large format tiles (600mm or larger) have at least 12–15% wastage for breakage during cutting.
  • Natural stone tiles have at least 20% wastage — vein matching, directional cuts, and natural defects generate high offcut volumes.
✓Tile Selection+
  • Tile PEI wear rating is appropriate for the location — PEI 1–2 for walls only, PEI 3 for light residential floors, PEI 4–5 for heavy residential and commercial.
  • Anti-slip rating (R-value or wet pendulum) is confirmed for wet area floors — minimum R10 for bathrooms, R11 for outdoor.
  • Floor tile thickness is sufficient for the application — 8–10mm for residential floors, 12mm for heavy use.
  • Tile rectification (precision-cut edges) was confirmed if joint widths under 2mm are intended.
  • All tiles were ordered from the same production lot (batch number) — colour and shade vary between lots.
  • A minimum of 5% extra tiles was retained after installation for future replacement of damaged tiles.
✓Substrate and Preparation+
  • The substrate (floor screed or wall plaster) was checked for flatness — maximum 3mm deviation under a 2m straight-edge for standard tiles.
  • The substrate was clean, dry, and free of dust, oil, paint, or curing compounds before tiling.
  • Wet areas (bathrooms, shower trays) had a waterproofing membrane applied and cured before tiling started.
  • Floor screed strength was confirmed adequate — minimum 15–20 N/mm² before tiling on a screed.
  • Movement joints were specified at maximum 4.5m in each direction for floor tiling and at all perimeters.
✓Purchase+
  • The quantity including wastage — not the net area — was used for ordering.
  • Tile sizes were confirmed physically from the packaging — nominal and actual tile sizes differ by the joint allowance.
  • Adhesive, grout, and movement joint sealant quantities were calculated separately using the respective calculators.
  • Delivery charges and taxes were confirmed separately.
Inspection Notes+
