Rising damp is water from the ground that transfers up a structure by capillary action. A wall in contact with the ground will become damp when ground moisture rises up it. This effect could typically lead to wood rot in skirting boards/timber floors, flaking paint, peeling wallpaper, salts and a tidemark effect.
Most types of masonry found in walls of a building will allow water movement by capillary action, although this is usually controlled by a traditional physical damp proof course (dpc). However, many older properties do not have a dpc in the walls, so where a dpc is absent, has broken down or is damaged, rising damp will occur.
Where this is the case then remedial damp proofing work is required which may include the installation of a chemical damp proof course system. Sovereign Chemicals Ltd supply a range of damp proofing treatments including, Injection Fluids and Injection Creams, along with installation equipment such as Injection Pumps and Guns.
Rising damp also introduces contaminating salts into walls and plaster which will require the plaster to be removed and replaced with specialist damp proofing materials. Sovereign also supply appropriate Renovating Plaster and Render suitable for this purpose.
