Rising Damp occurs in the walls of buildings when moisture from the ground rises up through building materials due to a process known as Capillary Action.

Rising Damp is a very common issue in older buildings, either because no Damp Proof Membrane has been applied, or the existing Damp Proof Membrane has failed due to age or has been bridged.

All building materials are wettable and can absorb water just like a sponge. Appearing along the base of a wall, Rising Damp forms characteristic marks in affected areas. Salts and other nitrates from the ground, travel with the damp and then, by depositing as the moisture evaporates, create marks indicating the presence of damp walls.

Furthermore, wall coatings such as vinyl wallpapers, prevent the moisture from evaporating. This worsens the issue by forcing the damp further up the wall. If allowed to continue untreated damp walls caused by rising damp can result in plaster and other wall materials rapidly decaying. It can also lead to Wet or Dry Rot developing in untreated timbers which are in contact with the damp walls.

Rising Damp Effects

Current Building Regulations require the presence of an effective Damp Proof Membrane in all new construction projects. Older buildings that never had a Damp Proof Membrane applied, or where the original Damp Proof Membrane has failed, the Rising Damp must be treated in place.

It is vital that a Rising Damp treatment course is started as soon as the dampness is discovered. A proactive response minimises any further damage to the building structure. As well as reducing the likelihood of mould spore formation; which can lead to severe Respiratory Illnesses. This is of particular concern if the mould forms in bedrooms.

Damp Treatments

There are two main types of effective treatment for Rising Damp – Chemical Injection and Electro Osmosis.

Chemical Injection

Chemical Injection is a highly effective treatment method for Rising Damp in-situ. A solvent-free cream is injected into the base of the damp wall and it quickly spreads to create a moisture-repelling barrier. Due to its unique silicone formulation and emulsion base, this solution creates a damp-proof network permeable to water vapour. Meaning the damp walls are free to dry out naturally.

Cream injection is both ecologically safe and non-hazardous to humans.

Electro Osmosis

A highly innovative and powerful treatment, Electro Osmosis works as a rising damp solution by introducing a very small and perfectly safe electrical charge into the damp wall. This solution involves the use of a series of titanium anodes which are inserted into the damp wall just above ground level. They repel the rising moisture molecules down the wall and harmlessly back into the ground. As long as this tiny positive charge is maintained, the wall remains dry and damp free.

Importantly, the use of grade 1 commercially pure titanium in this system gives it outstanding reliability. The power unit; complete with an automatic L.E.D. for circuit malfunction detection, enjoys extremely low power consumption. Following fitting, the treated area is re-plastered to ensure the entire system is invisible.
