Damp proof membrane walls

What is rising damp

Wall finishes for Newton damp proof membranesWith the high level of rainfall in the UK, the average home is subjected to a lot of rainwater, so it is no surprise that damp can become a big problem for many. Damp on internal walls can look very unsightly, often causes a bad smell in the house, and can cause permanent damage to plaster, paint and finishes. It can also be bad for our health, aggravating respiratory problems and encouraging the emergence of mites and mould. Damp proofing internal walls is essential for walls affected by damp – but firstly it is important to identify the cause of the damp problems.

Identifying The Cause Of The Dampness

Common damp problems and possible causes include:

– Rising Damp

  • Lack of a damp proof course in old houses
  • Failure of the damp proof course
  • Ground levels that are higher than the internal floor level

– Penetrating Damp

  • Cracked masonry
  • Poor pointing
  • Defective rainwater goods such as gutters or downpipes
  • Penetration from driving rain

– Condensation

  • Poorly ventilated rooms
  • Areas of high humidity e.g. bathrooms
  • The appearance of mould on the walls

Treating A Damp Wall With Newton Damp Proof MembranesNewton Damp Proofing Membranes

Newton damp proof membranes are made from High Density Polyethylene and Polypropylene which means that they are impervious to moisture and moisture vapour. The surface of the membranes are formed into a stud formation – this ‘egg box’ stud profile is a major advantage when treating damp. When applied to an internal wall, the stud profile allows moisture to evaporate from the wall unhindered which means that there is no danger of the dampness being guided else where which is a risk with some other systems.
