Rising Damp

 

 
 
 

 

Rising Damp Explained:

Moisture bypasses's the  Damp Proof Course (DPC) and rises up into the walls to create rising damp. Builders will place  Damp Proof Course (DPC) horisontally into the wall to specifically stop damp entering into the wall and failure of the Damp Proof Course (DPC) will result in Rising damp. Bricks and plaster suck up moisture just like a sponge and will assist in creating serious rising damp problems. The diagram below illustrate how moisture bypasses the Damp Proof Course (DPC) and results in rising damp.

Rising Damp causes paint to bubble

There are various types of salts residing inside plaster, mortar and the bricks. With out getting to technical, rising damp and salts chemically bind and creates massive volume growth resulting in paint blistering and bubbling. Salts are corrosive thus assisting in the paint loosening its grip on the plaster surface. Persistent rising damp will create an unstoppable chemical chain reaction that will result in paint continuously bubbling and blistering.
