What Causes Rising Damp?

Posted on: March 1st, 2020 by Jane F

Damp comes in many different forms but out of them all rising damp can be considered as the most disturbing. Just so you know, rising damp is a major problem not only in the UK but also in the whole world. This is among the primary reasons why building materials like concrete, bricks, and stone end up decaying. Even during the initial phase, rising damp can cause damages on external finishes and produce unpleasant odours. But, what is rising damp in the first place? What causes this worldwide phenomenon?

Rising Damp – A Quick Definition

Rising damp refers to slow movement of water that starts from the walls’ bottom portion to the higher portion. This concern is common not only in older buildings but also in new houses with flaws in construction. 

This takes place once the moisture coming from the ground rises up to the gaps in between bricks and through the tiny cracks in the masonry work. This can also be because of the water’s adhesive property that lets it move upwards while pulling other droplets with it. This process is what you call capillary action. 

Once moisture deposits in a building’s walls, this can result to significant damage to its overall appearance after some time. This is why it is important that you detect what causes rising damp to prevent further damages. 

Rising Damp and Its Causes 

Dampness is directly related to the existence of mould in different parts of the building affected by moisture. It is not a secret that mould has a very high growth factor with the ability to quickly spread when the conditions are favourable. It is also among the primary reasons behind damp concerns since this encourages moisture to spread. 

Many people might assume that damp is coming from the walls. However, more often than not, this comes from the ground. This means that rising damp takes place once the moisture that sits under the structure comes out as humidity.
