Damp Proof Membrane

Our loose laid, polyethylene damp proof membrane is ideal for use on solid concrete ground floors, enabling you to protect buildings against moisture, rising water and damp from the ground.

It’s a 0.3mm thick membrane and available in a 4 x 25m roll size covering 100 SQ/M. The product is manufactured from a blend of polyethylene, which remain flexible at low temperatures, stable at high temperatures and are resistant to ageing and deterioration.

What are the key qualities of damp proof membrane?

There are a variety of qualities to a good dpc membrane or dpm membrane, with the benefits of our damp proof membrane including:

  • The membrane provides a highly effective barrier to the passage of moisture from the ground and will enable a floor to comply with the requirements of the national Building Regulations, when installed in accordance with the manufacturer’s instructions.
  • The product has an excellent resistance to puncture. On smooth or blinded surfaces, they will not be damaged by normal foot or site traffic, though care must be taken to avoid damage during installation, particularly when handling building materials and equipment over the surface and when placing concrete or screeds, since they can be punctured by sharp objects.
  • Our CE approved 1200 Gauge DPM damp-proof membrane is manufactured to last the lifetime of the floor construction if it is correctly installed and not damaged by subsequent building operations.

What are the main applications of damp proof membrane?

When it comes to the application of dpm membrane, you should be aware that:
  • DPM should be laid with overlaps of at least 150mm and sealed to produce a water-proof and vapour-proof joint. This can be achieved with the use of double-sided sealant tape.
  • The DPM should be continuous with the damp-proof course. Where the DPM and DPC meet, they should be overlapped at a minimum of 100mm and a sealed joint formed with appropriate sealant tape.
  • When laid below the slab, the DPM should be laid on a bed of material which will not damage the membrane. When placed above slab, the surface should be free from debris and any projections which may damage the membrane. 
  • Detail work should be completed first. Once completed, DPM may be laid and overlapped and sealed with sealant tape. The membrane should be rolled down firmly to ensure an effective bond and seal.

What are the key features of damp proof membrane?

We ensure the highest quality in all of our DPM products, with the key features of dpm membrane being: 

  • High-quality damp proof membrane prevents the ingress of moisture into buildings
