Rising damp occurs when there is inadequate protection in the building’s foundation to block groundwater and/or by rain water penetrating cracked or badly installed damp proof course (DPC). Herbert explained how the problem sometimes only manifests years after construction is complete, and is more prevalent in a lot of the older houses in areas such as Woodstock, Salt River and Observatory where moisture tends to sneak through structural cracks.

We recommend that people closely supervise the construction of their homes to make sure that all cement work is done properly, and that there are no cracks evident – these make the walls porous and susceptible to dampness. Although every measure should be taken to ensure correct waterproofing during the build, sometimes these cracks are caused by uncleared tree roots or branches that have grown over time.

Whilst rising damp issues can occur throughout the year, people usually tend to notice the dampness in the rainy seasons.  Damp causes the discoloration or staining of the walls, a noticeable smell of moisture, diminishing of grout, and the presence of mould. Aside from the structural damage, damp can also cause some nasty health problems, especially to those who suffer from asthma.
