Efflorescence: White salt deposits on walls due to moisture migration.
Peeling Paint and Plaster Damage: Damp walls lead to flaking paint and disintegrating plaster.
Mold Growth: Damp conditions encourage mold and fungi, leading to health risks.
Corrosion of Metals: Moisture accelerates rusting of reinforcement bars and metal fixtures.
Electrical Hazards: Increased conductivity of wet surfaces can cause short circuits.
Causes of Dampness
Poor Drainage System: Inefficient water disposal leads to moisture accumulation.
Capillary Rise of Moisture: Water rises through porous building materials due to surface tension.
Leakage from Roof and Walls: Poor roofing and inadequate wall protection allow water ingress.
Condensation: Internal moisture due to temperature differences results in damp patches.
Improper Construction Techniques: Inadequate mortar joints and improper materials contribute to dampness.
Sources of Dampness in Buildings
Groundwater: Moisture rising from soil into walls and floors.
Rainwater Penetration: Through walls, roofs, and parapets due to cracks.
Leakage from Plumbing: Faulty pipes and drainage systems.
Humid Climate Conditions: High atmospheric moisture leading to condensation.
Methods of Damp Proofing
Membrane Damp Proofing: Using sheets of bitumen, mastic asphalt, or polythene.
