Water pouring through building expansion joints

Multi-block apartment complexes in Guwahati rely on expansion joints to move safely — but failed joint seals become highways for monsoon water into parking and flats.

Symptoms

• Water through joint during rain
• Stains along joint line on ceiling
• Joint filler cracked or missing
• Leak at podium level parking

Diagnosis

Joint width measurement across seasons, movement assessment, and water test. Proper joint system selected for actual movement range.

Can expansion joints be made 100% watertight?

With correct profile, backing rod, and flexible sealant — yes, for designed movement range.
