Building: Essence of Damp Proof Membrane (DPM)

When it comes to protecting your building from the damaging effects of moisture, damp-proof membranes (DPMs) are a critical element.
However, ensuring proper installation and selecting the right materials requires expertise. That’s where hiring a professional comes in.

What is a Damp Proof Membrane?

A damp-proof membrane is a thin, impermeable sheet material, usually made from polyethylene, that acts as a barrier to prevent moisture from seeping into a building’s structure.
It’s used in various construction applications, primarily on floors, walls, and basements.

Why So Important?

  1. Prevention of Rising Damp
    Ground moisture can rise through porous materials like concrete via capillary action.
    A professional understands the best placement and installation techniques for DPMs to block this moisture, preventing damp patches, peeling paint, and structural weakening.
  2. Protection Against Mold and Mildew
    Excess moisture creates a breeding ground for mold and mildew, leading to health issues and damage to building finishes.
    Professionals ensure DPMs are properly installed, promoting a healthier indoor environment.
  3. Structural Integrity
    Over time, moisture weakens building materials. Hiring a professional means your DPM is correctly fitted, protecting your investment for years to come.
  4. Improved Energy Efficiency
    Damp insulation loses its effectiveness. A professional can integrate DPMs into your building design for improved insulation performance, helping you save on energy costs.
