What exactly is rising damp?

What is rising damp? This is one of the most common questions we are asked at Wise Property Care. In short, rising damp in buildings occurs when water from the ground rises up through the bricks and mortar of a building by capillary action. In simple terms, the water rises up the porous wall of a building in the same way water is soaked up by a sponge in a sink.

How to Treat Rising Damp

What is rising damp – why it happens?

Any masonry structure unprotected by a properly installed course to prevent rising damp is susceptible to natural rising damp. Damp will rise by capillary action through the pores of the masonry seeking a means of evaporation. 

The moisture will continue to rise until it reaches a height where, unless no evaporation is possible, gravity takes over and pulls it down again. This height is seldom more than 1.20m, although deposits of ‘salts’ may be found higher in the wall, often driven there by the use of non-breathing plasters, renders, ‘tanking’, paints or vinyl wall papers.

Identifying rising damp

The tell tale signs of rising damp include a "tide-mark" on the wall above skirting boards of up to 1 metre however, it is important to remember that there are many forms of damp that can affect a property.  Check out our guide to how to identify rising damp for more information.
