RISING DAMP

What is Rising Damp/ Salt damp?

Stacks Image 2904

All buildings are surrounded by moisture that is trying to get into the dry structure of the property. However if your property defensives are inadequate, this is when damp problems occur.

Building built after approx 1892 had a damp proof course fitted as standard however these break down during time or damaged due to alterations to the property this then allows moisture to rise up through the wall called wicking or capillary this then travels through the wall to the inner skin via blocked cavity or no cavity wall due to age of building.

Over time the moisture rises up the wall then receeds every time it rises it brings hygroscopic salts with it up from the ground, these salts keep rising every time more moisture rises up and then reduces it leaves more hygroscopic salts it then breaks through the plaster contaminating the plaster and damaging the decoration, once salt is exposed to atmosphere in the room it attracts more moisture from the room, this is a circle that just keeps getting worse.
