Rising Dampness can be a nagging problem and if not deal properly, it will keep on increasing. It is the slow upward movement of water in the lower parts of your building walls. It causes the building to lose its appearance and leads to the deterioration of the wall plaster. Beside this, if the timber decay is allowed to stay, it can be unhealthy for the occupants. What’s more, if the problem is not dealt with properly the situation aggravates. So to deal with rising dampness you will have to first understand the construction of your building thoroughly, this is because the construction of an old building differs from the new building.
Any remedial measure that you undertake will only be successful if you have diagnosed the problem accurately. However, there are some initial measures that will help you take control of the situation till you find the source of the problem. You will have to clear any blocked rain water in your building, immediately. Check your drainage system, there can be something stuck to it which is causing water blockage. Fix it and allow the water to start flowing.
As a concrete measure you can opt to use a physical damp proof course. In this method you can cut small sections into the building wall (the mortar wall), now in these small sections, damp proof course material is stuffed in. This material keeps the water away and prevents it from rising. This method is not very popular as this can not be done by you at home. You will need professional contractors for this, however, this is the most effective way to control rising dampness.
A very common method, widely used these days, is to treat the rising dampness by injecting a chemical (liquid or cream) into the bricks or the cement. A chemical solution is injected into the walls to prevent the dampness from rising. This solution helps in repelling water from the wall, hence dampness is prevented. The effectiveness of this method is entirely dependent upon the formulation of the chemical solution. There are some injectable creams available in the market, approved by the British Board of Agreement. You can shop for these to get assured results.
You can even go for porous tubes along the lower part of your wall. These tubes when inserted into the lower part of the wall, encourage evaporation, hence the dampness is not allowed to rise further. However, according to some studies this method is not very effective for severe dampness.
Improving the drainage around the walls also help in reduction of rising dampness, this method is called Land Drainage. You need to dig a trench around the affected wall from the outside and lay a porous pipe into it. Then the trench is filled again with a porous material. Now, through these pipes and porous material, excess water is drained so the walls have lesser amount of water to be absorbed, hence the dampness is reduced. However, if you have shallow footings then it is recommended not to use this method.
