Rising damp plaster damage

Rising Damp Causing Plaster Damage

As rising damp brings moisture from the ground into a wall, it carries with it soluble salts which may be deposited in the wall fabric and plaster as the moisture evaporates. Certain of these salts, in particular chlorides and nitrates, are hygroscopic; that is to say, they are capable of attracting and absorbing moisture from the atmosphere when the relative humidity is high.

Damage was evident on the wall of this toilet in social housing in London when our CSSW-qualified surveyor visited.

Damp meter reading

We recommended that the walls be treated for rising damp and then re-plastered to an even height of 1.2 metres strictly in accordance with our specification for a Premier salt-retardant plastering system.

The project was quickly and efficiently completed with minimum disruption to the tenant.
