DPM, or Damp Proof Membrane, thickness varies depending on the specific product and its intended use. However, one common example is a 1200 gauge membrane, which has a thickness of 300μm (0.3mm).
Understanding DPM Thickness
The thickness of a DPM is a crucial factor determining its effectiveness in protecting against moisture. A thicker membrane generally offers better protection and puncture resistance. While a 300μm DPM is suitable for many applications, thinner or thicker options exist depending on the project requirements and the level of protection needed.
-
Example: A 1200 gauge membrane with a 300μm thickness is strong enough to withstand foot traffic and even wheelbarrows on smooth surfaces.
-
Factors influencing thickness: The required thickness of DPM will depend on factors such as the ground conditions, the type of construction, and the expected level of ground moisture.
-
Importance of correct thickness: Using an inadequate DPM thickness can lead to moisture ingress, causing damage to the building structure and potentially leading to mold growth and other problems.
