Rising damp

By rising damp is meant groundwater and rainwater that is transported up through the wall by the suction (capillary) action of the masonry.

How can you identify rising damp in your house?

If brickwork remains damp eventually the plasterwork on the inside of the wall will become loose and fall off and black mould will appear on the wall. The consequences under the floor can be more serious if, for example, the ends of the floor beams rot.

 Other signs are:
- Wallpaper coming off the wall
- Water in the cellar
- Damp walls
- Damp smell
- Condensation on the windows

There are many misunderstandings about rising damp:

As a result of poor ventilation in combination with double-glazing, the humidity in the house can be so high that mouldy patches appear on the wall. To see whether there actually is rising damp or of whether the humidity in the house is too high it is advisable to fill in the questionnaire (PDF) about this and send it to us. If you have any questions you can always contact us by telephone or e-mail. One of our technical advisers will be pleased to speak to you.

The Solution

By creating a sealing layer in the brickwork groundwater is prevented from rising above the level of your floor. This seal is made by saturating the wall with MBA4. MBA4 is an acrylic gel that is injected into the wall. MBA4 has been developed and tested in-house by B&W Vochtwering. (Download MBA4 test certificates). We have 15 years experience with this injection substance and have already treated thousands of houses.
