A Damp Proof Course (DPC) is a continuous, impermeable horizontal barrier installed in foundation walls—usually at plinth level (150–300 mm above ground level)—to stop ground moisture from rising upward through capillary action.
Why DPC is Essential for Foundation Protection
Prevents Rising Damp: Blocks groundwater from soaking into bricks, blocks, and mortar.
Protects Finishes: Stops paint peeling, bubbling plaster, mold growth, and white salty stains (efflorescence) on interior and exterior walls.
Maintains Structural Strength: Prevents long-term corrosion of embedded metal and structural decay of masonry.
