A damp proof membrane (DPM) is a material used in construction to prevent moisture from entering a building's walls, floors, and other structural elements. DPMs are important because they:
Protect the building: DPMs help maintain the structural integrity of a building by preventing moisture from causing problems like rot, mold, and corrosion.
Improve comfort and energy efficiency: DPMs can help improve a building's comfort and energy efficiency.
Prevent health risks: Mold and mildew can compromise indoor air quality and cause health issues.
