What causes rising damp?

When it comes to what causes rising damp, the first thing we need to point out is that within the UK, more often than not, ground soil where building and homes are built will have moisture. The question is not necessarily what causes rising damp but how do we prevent this moisture from travelling through masonry pores and manifesting itself in the appearance of rising damp.

Typical causes of rising damp

In most cases the cause of rising damp is due to moisture managing to bypass the rising damp barrier due to:

  • Deterioration or damage
  • Age
  • Human intervention bridging over the barrier
  • Properties not having any form of rising damp barrier in place

Any structure unprotected by adequately installed rising damp barrier will be susceptible to natural rising damp. Moisture from the ground travel upwards through masonry pores looking for a way for a way to evaporate before gravity takes over and draws the moisture back down again. The same effects occur when you place a brick in a shallow tray of water.

Sometimes the rising damp barrier can remain intact, but is bridged.  In other words, the brickwork above the rising damp barrier is able to absorb moisture and bypassing the rising damp barrier. This is normally due to external factors such as the ground level being risen above the current rising damp barrier by a newly installed flowerbed or a new driveway.

As with all types of damp however,  finding the cause of the rising damp issue is the first step to treating rising damp.
