Where Does Rising Damp Come From?

09 Sep Where Does Rising Damp Come From?

A common problem for buildings across the UK

Rising damp is often misdiagnosed in buildings where damp has entered the property through an unknown source.

It occurs when water from the ground finds a way to rise up through the bricks and mortar of a building using a capillary action – this is where water is literally sucked up the wall via small tubes or holes that form in the building.

Rising damp can normally only travel so far up a wall, roughly 1.2metres high, as the strength of gravity overpowers the capillary action and prevents the water moving any higher.

You can often identify a rising damp problem by its ‘tide line’ of yellow or brown staining that moves slowly up a wall, internally or externally. You may also find that your skirting boards and floorboards are damp or rotting.

In some cases, you can also notice small fluffy white deposits on your plaster – this is actually salt that has been washed out of the bricks and onto your plaster.

The best way to prevent rising damp is the installation of a damp proof course which provides a waterproof layer within your walls that stops water being able to rise up your building.

If you are too late with this and your property is already suffering from rising damp, there are a number of different treatments available. However, before treatment can begin, the source of the problem should always be located and treated as a priority.
