What causes rising damp problems in buildings?
Damp problems in a building can cause major issues within the structure. These issues can include rotting in timber structures, and concrete cancer or degradation of concrete and brickwork/mortar in concrete/brick structures.
Rising damp is the term used for the slow movement of water from the lower parts of a structure to higher parts of the structure. This occurs when groundwater rises up vertically through the pores of a wall structure, through a process called capillary action. When this moisture infiltrates the walls of a building it can cause damage to its integrity and physical appearance.
Rising damp and other damp issues in structures are usually caused by poor initial application of damp proofing systems, or degradation over time. Low lying areas close or below the water table are most susceptible to these types of issues.
Treatment options for rising damp
Rising damp can be repaired by creating a new damp proof course, by injecting a specialised solution into the base of affected walls, dependant on construction. In other applications, a physical damp proof course can be installed.
With the high number of brick constructed homes and buildings in NSW, this is a common problem, especially buildings over 25 years of age.
Other damp proofing systems include:
Installation of adequate ventilation
Subterranean or negative applied waterproofing systems
Installation of adequate drainage to remove water from affected areas
Installation of cross cavity flashings into cavity walls, to allow water to escape the cavity
Sub floor damp proofing
CBK are specialists in all types of damp proofing, including diagnosis. Our technicians are all trained and certified in these types of systems. Once the cause of the issue is identified, a permanent a cost effective solution will be specified by our team.
