Water travelling through concrete slabs

Hidden slab leaks from embedded pipes or honeycombed concrete cause ceiling damage far from the source — common in Guwahati bathrooms and kitchens.

Symptoms

• Random ceiling damp spots
• Water meter running when taps off
• Warm spot on floor (hot pipe leak)
• Hollow sound in slab

Diagnosis

Thermal imaging, acoustic leak detection, and selective core test.

Can PU injection fix slab leaks?

Yes for porous concrete and some joint leaks — not for burst pipes (plumbing fix needed first).
