Rising Damp

 If you’ve noticed a suspicious looking damp patch, call A.Dobing now, for expert help.

What Is Rising Damp?

The soil surrounding buildings is naturally moist, and brickwork is porous, so over time bricks absorb  this moisture, creating a dark, wet-looking staining on the wall. Once in the brickwork, the water begins to evaporate, causing a number of problems. Firstly, this evaporation of water into the property will elevate the humidity levels inside, putting the building at risk of further complications such as wood rot and insect infestations. Secondly, the process of evaporation leaves behind a salty residue which damages plaster, wallpaper and paintwork.  

 Rising damp should not be ignored, as it can lead to significant structural problems which will be costly and time consuming to rectify. If you suspect you have a damp problem, call A.Dobing to arrange an inspection.

What Causes Rising Damp?

In most properties, a waterproof membrane, known as a damp proof course, is installed during the construction process. This barrier sits between the layers of brickwork, a few inches above ground level, and prevents moisture climbing up into the brickwork above it. On many properties if you look a brick or two above the ground, you will be able to see a line that looks like a trapped plastic bag - this is the damp proof course.

In some houses, especially older properties this membrane has not been correctly installed, or there may never have been one installed at all.

It is also possible for a fully functional damp proof course to be ‘bridged’. This happens when an absorbent material helps moisture pass from ground level, into the brickwork above the membrane. An example of this would be if a raised flower bed is positioned against a wall, and the water from the soil is drawn into the bricks.

How Is Rising Damp Treated?

It is possible to inject a chemical damp proof membrane into the walls of a building, without compromising its structure. We have carried out this procedure countless times, even on historic listed buildings, to provide an effective barrier to water penetration. We also apply a waterproof salt-resistant render to the inside of the walls to prevent future problems.

Damp That Doesn’t Rise?

Not all damp is rising damp. A patch of plasterwork or bricks can be made damp by any contact with water. For example, if you have a damp area where an outside wall meets the ceiling, this could be caused by a blocked gutter overflowing onto the bricks outside. Regardless of the damp patch’s position, the source must be identified and fixed, as untreated damp can lead to expensive problems for your property.
