Groundwater rising through a wall due to capillary action is what causes rising damp. Bricks and mortar can be highly porous, with tiny capillaries which allow water to ascend. Salts in the seeping groundwater may stain plaster and cause permanent visual degradation.
Some homes were constructed without a damp-proof course, or the existing one has deteriorated, causing rising moisture and necessitating remedial action.
Rising damp is caused when a building’s damp proof course (DPC) has been compromised or hindered due to the surrounding ground level. Moisture containing salts and other minerals from the earth, such as nitrates and chlorides, will travel up into the brickwork and plastering of the walls. As these substances dissolve quickly in water they become increasingly present with an increase in moisture levels. To rectify this problem, our specialist team recommend using a damp-proofing cream injection which is both clean and effective.

Injecting cream is the most effective means of damp-proofing; however, it will be less successful if the issue has other sources. A survey should therefore take place prior to any implementation.
This property survey and report examines any damp issues in the building, assessing the severity of damage and outlining steps to address or reverse it.
Our surveyors, specialised in dampness, execute this procedure. They examine the location and amount of dampness as well as any damage it could cause if left untreated, identifying its type (wet rot, dry rot, condensation or other issues) and determining an effective solution. For more information regarding potential solutions to your damp problem please call our team on 01273 920588.
To treat and prevent rising damp, we employ various strategies. Injecting a silicone-based compound through tiny holes in the wall is one of the most efficient and economical solutions. When dried, it forms a water-repellent layer within the wall. Generally, some of the internal plaster bearing salt residue from moisture must be eradicated and replaced with salt-resistant plaster to enable natural drying of moisture contained in the wall.
After taking out the polluted plaster, it is recommended to install a new chemical damp proof course using a Silane/Siloxane cream solution and an advanced DPC injection cream. The afflicted walls should then be injected with this under pressure, followed by waterproofing the sand and cement render backing layer.
A tell-tale tide line of yellow or brown staining, blown plaster in the lower region of walls above skirting boards is a common indicator of rising damp. Additionally, decaying or moist skirting boards and floors may be present. While performing a short repair (e.g repointing or painting) may seem like an easy solution to rising damp now, it will only lead to more costly repairs at a later date.
For treating and curbing rising damp, we employ a selection of techniques and solutions. Injecting a siloxane-based chemical into the wall via several tiny holes is one of the most economical treatments, delivering significant long-term success at an affordable cost.
A damp proof course is a barrier that prevents water from entering the wall via capillary action. It runs the length and width of the wall to ensure waterproofing.
A special membrane, a damp proof membrane (DPM), is attached to the construction to guard against moisture. Polyethene material and shotcrete – which contains cement – are positioned beneath a sheet of concrete to manage water and pressure. Cavity walls between inner and outer walls keep out water whilst masonry walls are sealed with pressure grouting; this is an effective way of shielding structures from water and humidity such as rain.
Almost all walls respond effectively to damp-proofing creams. This is important, as no two rising-damp affected walls are the same; the mortar used to construct them can vary greatly and have a major influence on any solution’s success. For advice, please contact one of our specialists.
When it dries, a water-repellent barrier is formed inside the wall. Generally, some internal plaster affected by salts from rising damp needs to be taken away and switched with a salt-resistant plaster, allowing moisture within the wall to dry out naturally.
Constructing an optimum protection from rising damp lessens the moisture in the wall, thwarts accumulation of ground salts and minimises heat loss.
Independent studies conducted on houses around the world have certified the efficacy of this damp proofing cream in a wide range of scenarios.
Mortar with a lime base can be used to construct buildings and walls. It is made from a combination of hydrated lime, sand, and water, mixed together in the proper proportion. The ratio of ingredients should be one part hydrated lime to three parts sand. Once the mortar has been mixed together it should be left for 24 hours before use.
Exterior wall rising dampness can lead to rendering damage, efflorescence and masonry cracks. Applying a damp-proofing cream is recommended to eradicate this issue, thus preventing further harm to the walls.
An external masonry cream can be applied to the wall’s exterior for an additional layer of protection against moisture penetration. This is not done through injection.
The cost of a professional DPC injection varies depending on location and provider; however, one can usually assume around £70 per metre for wall treatment – amounting to approximately £275-£300 per wall.
The injection alone is the price quoted; additional cosmetic work such as repainting and plastering post-treatment will raise the total cost. However, these efforts will create a more enjoyable environment in your building, providing you with lasting assurance that dampness won’t be an issue for years to come.
Our damp proofing experts will thoroughly assess and identify the severity of your damp issue. Our services offer tailored treatments and knowledgeable technical advice to tackle all forms of property-related dampness: rising damp, woodworm, dry rot, condensation, and structural waterproofing.
