Rising Damp

Damp control and prevention 
in Somerset

Almost all buildings and structures that are exposed to the elements will be prone to water ingress at some point. If this water ingress is left unchecked it can cause severe damage to the property, possibly causing structural failure and thus leading to major repair costs for the owners.

Damp prevention

Rising damp occurs when either the original damp proof membranes have broken down or a damp proof membrane was not installed when the property was built. Moisture from the ground rises through the masonry substrate of a building through capillary action. The height to which the water will rise depends on several factors including pore structure of the bricks and mortar and the rate of evaporation. Masonry containing a high proportion of fine pores will allow the water to rise higher than a coarse pored material.

Generally rising damp is often first noticed by the damage it can cause to buildings. The unwanted moisture enables the growth of various fungi in wood, causing rot. Plaster and paint deteriorates and wallpaper loosens. Stains from the damp can mark surfaces. Externally, mortar may crumble and salt stains may appear on the walls, as well as the formation of rust on the steel and iron fasteners. It may also cause respiratory illness in occupants. In extreme cases, mortar or plaster may fall away from the affected wall.

Professional damp control

Damp course injection is the method of injecting a water repellent chemical into the brick or mortar joint which lines the capillaries in the substrate. Once cured it creates a continuous water repellent barrier. This prevents damp from rising up the wall. All damp proof injection chemicals are highly effective and have been used by specialist contractors for over 20 years.

Damp course injection will cure rising damp but it is extremely important that the re-plastering specification is strictly adhered to and that the plasterer carrying out the work is made aware of the importance of the re-plastering being carried out to a suitable specification. Failure to carry out the re-plastering specification after the damp course injection may lead to any contaminated decorations to remain damp.
