What is Penetrating Damp?

Penetrating damp is a form of damp that can affect all types of properties, from those with solid brick walls to those built from stone. It forms as a result of water travelling inside a property from the outside.

There are a variety of penetrating damp causes, almost all of which can be prevented through the proper upkeep and maintenance of a property. However if penetrating damp has already affected your property, Prokil offer a variety of effective and reliable penetrating damp treatment and solutions. Our team of damp specialists are qualified in recognising the signs of penetrating damp and can advise how to prevent it from returning.

How Does Penetrating Damp Occur?

Penetrating damp can occur from a number of causes, however most commonly due to an excessive amount of water coming into contact with the building’s structure. If your building has been built with a solid wall, (generally those built prior to 1920’s had no cavity), then you are more likely to experience penetrating damp. This is because any defects externally will easily allow for the transfer of moisture to the internal face of the wall. In contrast, a cavity wall property means that any moisture from defects on the outside will not come into contact with the internal wall.

If you think you might be at risk of penetrating damp on internal or external walls due to suspected defects within your home or building, we can arrange a survey to determine whether you require penetrating damp treatment.

Some of the main causes that contribute towards penetrating damp include:

  • Overflowing gutters
  • Blocked or leaking pipes
  • Missing roof tiles
  • Old porous walls
  • Damaged brickwork
  • Damaged seals around doors and windows

Why Is Penetrating Damp A Problem?

The need for penetrating damp treatment usually increases the older the building is. This is because older properties tend to have undergone more changes over the years and also require more maintenance.

A huge problem with penetrating damp is that it does not take complete penetration through a wall to cause a significant amount of damage.

Penetrating damp that is left untouched can cause a variety of issues, such as:

  • Mould growth
  • Wet rot or dry rot
  • Decorative spoiling
  • Heat loss
  • Wood boring infestations
  • Damp cavity wall insulation
