S.No.CheckpointIS RequirementStatus
A. TEST PREPARATION
A1Waterproofing cure completed (minimum 7 days); surface hardness confirmed by scratch test
Acceptance: 7-day cure minimum; no indentation from finger nail; ready for water exposure
Cl. 402 — Cure verification
A2Test area isolated: Temporary dams/barriers constructed to contain water; perimeter sealed
Acceptance: Dams height ≥300mm; sealant prevents seepage; capacity minimum 50 liters for small areas
Cl. 402 — Test setup
A3Underside of test area monitored: Observation points established to detect leakage immediately
Acceptance: Observation points at corners and center; white cloth placed to detect damp; inspection hourly
Cl. 402 — Monitoring setup
A4Initial conditions documented: Photographs taken; surface condition noted; baseline established
Acceptance: Pre-test photos; surface visual record; underside photos; dated and labeled
Cl. 402 — Documentation
B. FLOOD TEST EXECUTION (WALLS)
B1Water filled to height 150-300mm above lowest point of test area; level marked
Acceptance: Water depth 150-300mm typical; marked on dam; temperature recorded (5-40°C acceptable)
Cl. 402 — Water application
B2Water maintained for 72 hours minimum; water level topped up to maintain height
Acceptance: 72-hour minimum; 7-14 days preferred for critical areas; level checked 2x daily; log maintained
Cl. 402 — Test duration
B3Underside monitored hourly for first 24 hours, then daily for duration; any dampness recorded
Acceptance: No moisture/dampness observed; white cloth remains dry; written log of observations
Cl. 402 — Leakage detection
B4Water drained carefully; test area allowed to dry for 7 days; underside re-inspected
Acceptance: Slow drain to avoid damage; drying period 7 days; final underside inspection shows no staining/mold
Cl. 402 — Post-test assessment
C. PONDING TEST EXECUTION (FLOORS/TERRACES)
C1Water ponded to depth 50-100mm; contained by temporary dams; level marked
Acceptance: Depth 50-100mm typical; dams form sealed perimeter; drain plug not opened during test
Cl. 402 — Ponding setup
C2Ponding maintained for 72 hours; water level monitored daily and topped up if needed
Acceptance: 72-hour minimum; 7 days preferred for roofs/terraces; daily level check; log maintained
Cl. 402 — Test duration
C3Underside/ceiling below test area monitored hourly during first 24hrs, then daily
Acceptance: No water drips observed; white cloth placed shows no dampness; observations logged hourly/daily
Cl. 402 — Leak detection
C4Water slowly drained through controlled outlet or pumped out; surface dried 7 days
Acceptance: Controlled slow drain; no rush-draining; drying period 7 days; final inspection for permanent staining
Cl. 402 — Drainage control
