Rising damp

Internal damp
A short description about our rising damp treatment methods
One of the most common ways in which rising damp is addressed in a building is the installation of a damp proof course when the building is constructed.
A damp proof course helps to prevent damp rising up the walls and damaging the property. Damage that can be caused from damp includes damage to plaster, resulting in redecoration, wet rot or even dry rot which can affect any unprotected timber.
Damp proofing can be applied in many different ways, at Harrison Building Services we opt for the less obtrusive method of injection.
As the description states, treatment is carried out by means of holes drilled into the cement joints of the walls, where the damp proof cream which is silicone-based then creates a water repellent barrier.
Holes should be drilled at the level of the damp proof course in order to apply the damp proof injection.
One of the most significant benefits of this type of treatment is that it can be applied to walls that have already suffered from a severe case of water saturation, meaning that a building could be saved when more extensive demolition and rebuilding work may otherwise have been necessary.
The damp proof cream we inject is a blend of silane/siloxane cream emulsion that reacts with moisture to form a highly effective hydrophobic barrier against rising damp in masonry structures. Produced as a viscous cream the efficacy is superior to paste formulations containing materials that serve no useful long-term purpose and which can leave an unsightly residue.
