Damp basement without visible flooding

Even without standing water, basements in Guwahati commercial buildings suffer high humidity from capillary rise and poor vapour barriers — damaging inventory and HVAC.

Symptoms

• High humidity readings
• Condensation on pipes and walls
• Mould on cardboard storage
• Sweating floor slab

Diagnosis

Hygrometer logging, slab moisture test, and drainage survey. Internal tanking vs external cutoff depends on access and water table.

Is basement dampness a health issue?

Yes — mould affects air quality. Commercial basements need humidity control plus source fix.
