Using Trouble-free Damp Proof Membranes

If you are looking for a damp proof membrane for walls, there is a lot that needs to be considered before you start

Damp proof membranes are best suited for walls that have just had the insertion of a new damp proof course. Most situations involving damp remedial treatment will be enough. Nevertheless, walls can start to be damaged by penetrating dampness. As a result makes sense to invest in a damp proof membrane for your walls, as it can be critical in terms of protecting the deteriorating surface.

If you are looking for a damp proof membrane for walls, there is a lot that needs to be considered. Some of the key features that you need to ensure is that the product you choose gives you the best adhesion, strength, and stability. However, it is critical to first diagnose any existing damp problems so that you can take the right course of action. So let’s have look at how these membranes work to stop damp.

What Are Damp Proof Membranes And How Do They Work?

Damp Proof Membranes are an exceptional solution in terms of preventing damp issues inside your property. DPM are made from plastic, which is how they stop water penetration. The surface of the membrane is created in a way which will generate an air gap. This allows the water to evaporate before travelling through the wall. As a result it will stop any moisture and vapour, along with contaminants and salts, from impacting the wall’s internal finish.

What Are Some Of The Qualities You Should Look Out For When Looking For Damp Proof Membrane For Walls?

DPM’s have a lot of different feature that you should be looking out for when purchasing. Some include:

  • Will the product be suitable for your construction?
  • How easy is the membrane to work with?
  • Does the DPM comply with building regulations?
  • How long has the membrane been manufactured to last?
  • Check what water vapour resistance the product offers?
  • How cost effective is the membrane?

These are just some of the features that you should check when researching for the best solution.

Membrane Thickness is Important

The damp proof membrane acts as a physical barrier between the new finish and the existing damp wall. Typically, the thickness will range anywhere from 0.5 mm to 1 mm, with stud sizes ranging from 1 mm to 8 mm. With a dry lining system a membrane is sometimes used with a finish. Other membranes have a welded mesh, which enables there to be plastering and rendering after application. The air gap or the cavity that is created by these membranes will allow approximately 10 litres of space between the wall and the membrane, creating that all important water barrier.

Damp Proof Membrane’s Life expectancy

These membranes in general have a long life expectancy, usually lasting for over three decades. In this time they will help prevent any damage to the structure and finish of a build, providing peace of mind.
