Rising Damp London
Rising damp is moisture contained in your walls due to water in the ground underneath or next to your walls rising up through the fabric of the wall, regardless of whether it be brick, block or stone. The water moves upwards via the wall as a result of capillary action via the tiny holes in the brick or stone.
The water ceases rising at a height where gravity counteracts the upwards force of the capillary action. This ‘rising damp’ ordinarily reaches a max height of 1.2m, however the consequences of the damp, for example salt deposits, is sometimes seen higher up due to the occurrence of non-breathing wall coverings such as vinyl wallpaper and non breathing plasters, renders and paints.
Rising Damp Survey
When it comes to conducting a rising damp survey we take the work very seriously.
Our surveyors will conduct a comprehensive rising damp survey before suggesting any treatment. With years of working experience and qualifications, our surveyors are the best in the business on the subject of diagnosing damp related issues and developing a bespoke treatment plan for the home.
Rising Damp Treatment
The most commonly encountered forms of rising damp treatment generally focus on the injection of a siliconate type chemical either in the form of solution or cream. The purpose of this is that it is in general the least difficult and most economical treatment to use within built properties. Determined by the thickness of the walls, this is often done by drilling holes in a ring around the affected wall( s ) and injecting the advised chemical or cream solution.
After a new rising damp treatment course has been installed, any salt affected plasterwork has to be renewed. If the plasterwork is not correctly removed and restored with specialist salt retardant plaster, the salts that are present in the plaster may possibly continuously take in moisture from the air despite the installation of a whole new retrofit damp proof course showing the physical appearance of dampness.
