Why your basement floods every monsoon

Basement leakage in Guwahati is rarely just a plumbing issue. High water table, poor external waterproofing, and cracked raft slabs let water push in from below and through walls.

Symptoms

• Water pooling on basement floor after rain
• Damp walls and white salt deposits (efflorescence)
• Musty smell and mould on stored items
• Pump running constantly during monsoon

Diagnosis

We map moisture ingress points, check slab cracks with NDT, and assess external grading. Hydrostatic pressure tests confirm whether water is entering from below or through walls.

Can basement leakage damage columns?

Yes. Persistent moisture corrodes column base reinforcement — weakening the entire structure silently.

How long does basement waterproofing last?

Proper external + internal system with crack repair typically lasts 10–15 years with maintenance.
