Impact of Rising Damp on Buildings

Rising damp is a significant problem that can cause severe damage to buildings. It occurs when groundwater seeps up through the ground and enters a building's walls. This can be caused by a number of factors, including:

• Poor drainage around the building


• Cracks in the foundation or walls


• A high water table

When rising damp occurs, it can cause a number of problems, including:

• Damage to the building's structure


• Mold and mildew growth


• Musty odors


• Increased energy costs


• Health problems for occupants

What is an Acceptable Damp Reading?

The acceptable damp reading for a building varies depending on the material of the walls. However, as a general rule, a damp reading of less than 15% is considered acceptable. Readings between 15% and 25% indicate a moderate risk of dampness, while readings above 25% indicate a high risk of dampness.

How to Prevent Rising Damp

There are a number of ways to prevent rising damp, including:

• Ensure that the ground around the building is well-drained


• Seal any cracks in the foundation or walls


• Install a damp-proof membrane


• Use a dehumidifier to reduce the moisture levels in the building

If you are experiencing problems with rising damp, it is important to contact a qualified professional to assess the problem and recommend the best course of action.
