S.No.CheckpointIS RequirementStatus
1. SCOPE & OBJECTIVES
1.1Scope: Define areas to be waterproofed (zones, rooms, structures); total area in m²
Acceptance: Clear identification of building/floor/zones; total area quantified; high-risk areas identified		Cl. 401 — Scope definition
1.2Objectives: State waterproofing standard, durability target, performance requirements
Acceptance: IS 2645 compliance; 10-20 year durability typical; zero seepage target; flood test mandatory		Cl. 401 — Goal setting
2. MATERIALS & SPECIFICATION
2.1Waterproofing product: Type (liquid/sheet), brand, grade, approval; supplier & test certs
Acceptance: Approved waterproofing system; test certificates <6 months old; storage/shelf-life confirmed		Cl. 401 — Material approval
2.2Primer/Bonding Agent: Type, consumption rate (kg/m²), drying time specification
Acceptance: Primer consumption 0.5 kg/m² typical; drying 24-48 hrs before main coat; compatibility confirmed		Cl. 401 — Primer specification
2.3Application rate: Liquid (kg/m² per coat) or sheet (weight/area); total DFT target
Acceptance: Liquid: 1-1.5 kg/m² 1st coat, 0.5-1.5 kg/m² 2nd coat; total DFT ≥2.5mm typical		Cl. 401 — Application specification
2.4Quality Standard: IS 2645 compliance; zero-seepage requirement; flood test protocol
Acceptance: All materials and procedures conform to IS 2645; flood test 72 hours minimum		Cl. 401 — Standard compliance
3. EQUIPMENT & TOOLS
3.1Application equipment: Spray gun, roller, brush type/condition; calibration verified
Acceptance: Spray gun: 2-3 bar pressure, 0.3-0.5m fan width; roller: 10mm nap; brush: synthetic, lint-free		Cl. 401 — Equipment specification
3.2Measuring equipment: Scales (material weight), measuring tape (area), thickness gauge (DFT)
Acceptance: Scales calibrated ±2%; measuring tape certified; DFT gauge calibrated ±25 microns		Cl. 401 — Measurement tools
3.3Environmental monitoring: Thermometer (air/substrate), hygrometer (humidity), barometer
Acceptance: Thermometer ±1°C; hygrometer ±5%; monitoring 2x daily minimum		Cl. 401 — Environmental control
