What is rainwater ingress?
In 2018, less than half of the properties we inspected warranted damp proofing treatment only. In many cases, there is another cause of damp, or in some cases, several causes. One of the most common, is rainwater ingress.
When water enters the building, usually via an external defect, this is known as water ingress or penetrative dampness. The main causes are:
- Blocked or defective guttering
- Perished mortar beds (pointing)
- Defective roof coverings
- High external ground level
- Blocked cavities within walls

How to treat rainwater water ingress?
The key to treating water ingress is first to ensure that the problem has been diagnosed correctly.
Treatment will vary depending on the cause of the problem, so it could be anything from replacing a leaking gutter to replacing roof coverings and repointing walls.
However, if the water ingress has caused salt contamination which has penetrated the walls, the affected plaster may need to be replaced in order to solve the problem completely.
