Monsoon Waterproofing Checklist: Protect Your Roof & Walls

1. Terrace & Slab Inspection

Inspect the top roof slab for micro-cracks or standing water accumulation. Apply a multi-layer elastomeric polymer slurry coat combined with fiber mesh over brickbat coba.

2. External Wall Paint & Crack Filling

Seal all exterior wall hairline cracks with acrylic sealant before applying a 100% acrylic waterproof exterior paint system with anti-fungal protection.

3. Window & Balcony Sill Sealing

Audit silicon sealant joints around UPVC and aluminum window frames. Ensure rainwater drip molds (chajjas) are clear of debris.

4. Bathroom Membrane Testing

Perform 48-hour water ponding tests in master and guest bathrooms before laying floor tiles to verify polyurethane (PU) membrane integrity around drain outlets.

5. Downpipe & Drainage Clearance

Clear all terrace rainwater downpipes, gutter traps, and storm-water channels to prevent backup overflow into parapet walls.
