Damp proofing is a building treatment or method used to prevent moisture from passing through walls, floors, or foundations into the interior of a building.
Here’s a breakdown:
Purpose: To stop dampness (moisture from the ground, rain, or condensation) from seeping into structures, which can cause mold, decay, and structural damage.
Common Methods:
1. Damp Proof Course (DPC) – a barrier layer (often slate, plastic, or bitumen) inserted horizontally in walls near ground level to block rising damp.
2. Damp Proof Membrane (DPM) – a plastic sheet laid under concrete floors to prevent moisture from the ground rising into the floor.
3. Surface Coatings – applying bitumen, waterproof cement, or chemical coatings on walls or foundations.
4. Integral Damp Proofing – mixing water-repellent chemicals into concrete or mortar during construction.
Difference from Waterproofing:
Damp proofing resists moisture but may not withstand heavy water pressure.
Waterproofing provides a stronger barrier against both moisture and water under pressure (e.g., basements, underground structures).
⚒️ In short: Damp proofing = moisture control in buildings to keep interiors dry and healthy.
