Types of Damp

Damp is mainly caused by an excess of moisture in an improperly ventilated area. It often occurs in areas exposed to rain, condensation, and other direct sources of moisture. The main types of damp found in most buildings in the UK are rising damp, penetrating damp, and condensation damp.

Rising Damp

Penetrating Damp

Condensation Damp

Rising damp is a prominent cause of structural damage in buildings. A common reason for this kind of damp is a damaged, missing, or incorrect damp-proofing course (DPC) as a result of building regulations that have been incorrectly adhered to. The absence of a proper DPC allows groundwater to seep up into the masonry and saturate walls.

Over time, this constant saturation can lead to mould, blistering, peeling paint and wallpaper, and damaged render. Sandown Repointing and Wall Ties uses only the best products to protect your home against rising damp, including Safeguard Europe products such as Dry Zone.
Penetrating damp can occur in any building, regardless of age. This moisture is often visible as a damp patch on the internal wall and usually causes discolouration, peeling, and flaking of paint and wallpaper. It can also lead to moss growth, increased heat loss in winter, and frost damage when rain penetrates the masonry.

Penetrating damp is caused by rain seeping into the masonry of an improperly maintained building or as a result of poorly installed and maintained wall ties and cavity wall insulation. In some cases, rectifying these defects can cure and prevent penetrating damp from occurring. Other solutions include improving the weather-tightness of the masonry by using external render, cladding, or weatherproof paints. At Sandown Repointing and Wall Ties, our team uses only the best methods and products, including Storm Dry from Safeguard Europe, to guard your home against penetrating damp.
This kind of damp is a result of water vapour being unable to escape the building due to improper ventilation, causing water droplets to form on colder surfaces. This condensation provides the perfect environment for the growth of mould. To reduce the risk of problems related to condensation damp, proper ventilation and air exchange is essential, as it allows the water vapour from inside the property to escape and allows cooler, drier air to enter.
