| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. TEST PREPARATION | |||
| A1 | Waterproofing 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 | |
| A2 | Test 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 | |
| A3 | Underside 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 | |
| A4 | Initial 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) | |||
| B1 | Water 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 | |
| B2 | Water 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 | |
| B3 | Underside 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 | |
| B4 | Water 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) | |||
| C1 | Water 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 | |
| C2 | Ponding 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 | |
| C3 | Underside/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 | |
| C4 | Water 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 | |
