Rising Damp is caused by ground water seepage into the walls or foundation of a property at ground level. Rising Damp can be associated with areas that have a high water table and can happen in an area suddenly after years of not having issues. Moisture will travel up the porous parts of the wall and soak the bricks and mortar through the process of capillary action. This means that the water soaks up the wall through the porous areas generally in the mortar joints until it reaches your plasterwork and then becomes visible. Damp will usually not rise higher than 1.4 meters (or 4 ft 6in) due to the effects of gravity. Rising Damp can commonly occur at times when your local areas water table has risen and your property has no or insufficient damp proof course (DPC).
What effects can it have?
Along with some health issues due to the effect of dampness, rising damp can have a major effect on the structure of the property if left untreated. You will notice Rising Damp by “tide marks” on the base of the wall above the skirting level. It can lead to paint and plaster falling off the walls as well as issues like mould and musty odours. Rising Damp will also decay any wall based timers in the affected area. If left untreated this can lead to the weakening of the wall based timbers which are at risk of being infected by Dry Rot and Wet Rot. Usually the timbers will be integral to the structure of the building so it’s imperative that the Rising Damp be stopped and any rotten timbers be treated or replaced. In some severe cases a structural engineer may need to be consulted to ensure the long term integrity of the building.
How to Treat Rising Damp?
Chemical Injection Damp Proofing
In most cases, the blown plasterwork on the wall will be removed and safely discarded by the dampstore. Then the process of injecting a Chemical Damp proof course is carried out by the Damp Store. This is the preferred method of rising damp treatment to fix damp problems. Other methods work well in specific use cases like lectros osmosis and ultracure DPC cream
After the chemical injection has taken place it is imperative that a form of waterproof breathable tanking slurry is applied to the surface of the damp wall, preventing any residual damp. This forms a vertical damp proof barrier to stop that dampness coming through to the new plaster.
After the walls have been damp proofed and the products have sufficiently cured, the Damp Store will replaster the walls with a render and finally to a skim finish. Leaving it ready for Paint and Decorating. The Damp store can also arrange plumbing and electrics to be removed and reinstated as part of the works.
Damp Proof Course (DPC) methods are used to treat rising dampness within masonry walls and provide an effective barrier against rising damp in buildings which have no DPC or a Failed DPC It is usually recognised by a “tide mark” or moisture staining on the internal surface of the wall and usually rises up to 1-1.2m from floor level.
For negative side (inside) waterproofing against dampness in buildings and structures of all kinds (eg. basements, underground garages, under arches, rising damp). Also for positive side (outside) waterproofing of structures. The Damp Store’s specialist installers can ensure the tanking is applied correctly to ensure the rising damp does not return and affect your newly plastered walls.
After completing the Damp Proofing process. The Damp Store will apply several coats of Sand and Cement and/or Thermal Insulated board if required. Then Apply a skim finish which will be ready to paint within a few weeks
