A damp proof course is installed on the lower level of your property to prevent water from rising up your wall in an action known as rising damp. There are a range of damp proofing options available, including damp proof membranes and chemical options to name just a few of the most popular methods used.
Properties built after the 1950’s will more than likely already have a damp proof course installed, though in older properties this may have deteriorated over time, making it ineffective in preventing rising damp. If you are unsure about what kind, or even if you have, a damp proof course that is causing damp problems, our property survey will get to the root of the problem and we will provide a solution.
Brickwork and mortar is naturally porous and will gradually soak up water through capillary action, like a sponge, as it attempts to evaporate. The moisture will continue to climb upwards until it reaches a height of around 1.5 metres before gravity prevents it from going any further.
This is often how you can identify rising damp in comparison to penetrating damp, as rising damp is only rarely seen above this height, as well as only being possible on the ground floor. It is important that you treat rising damp as soon as you spot it to prevent the growth of mould, which can have negative effects on your health, and to prevent the decay of timber structures.
Rising damp is a tell-tale sign that your damp proof course has become defective and needs repair or replacement. We are experts in damp proofing solutions in Dorset & Hampshire, so if you’ve spotted signs of rising damp, contact us on 01202 737739.
