What rising damp means?<\/h3><\/div>
Rising damp is a vertical capillary movement of ground water in masonry.
\nA rising damp sign is often a visible tide-mark about 1m above floor level.
\nRising dampness is one of the main cause of dampness in buildings.
\nMost walls in new buildings have a physical barrier or damp proof course to prevent rising dampness, however, in older buildings or if the physical barrier has broken down, it is important to install a remedial damp proof course (DPC).
\nDuring the diagnosis, the surveyor must make sure the damp problem doesn\u2019t come from another damp issue such as plumbing defects, condensation or penetrating damp (rain water ingress).
\nHow to stop rising damp? See our method below.<\/p>\n

Damage of rising dampness: humidity in walls<\/h3><\/div>
<\/p>\n

Saltpeter, mold and fungus<\/h3>\n

A high humidity rate significantly promotes the development of molds and fungi.
\nThe saltpeter is deposited on the surface of the wall in the form of white crystals of cottony appearance.<\/p>\n

 <\/p>\n

Blistering and degradation<\/h3>\n

Water, migrating to the inner walls, causes the blistering and peeling of decorative paints and coatings.
\nThe salt stained plaster loses its hardness and adhesion. Decayed skirting boards and timber floors.<\/p>\n

Act in depth, for lasting results.<\/p>\n

Rising damp can be cured by the installation of a chemical damp proof course.<\/p>\n

Damp proofing keeps moisture out of a building thanks to the injection of a product to reduce the moisture transfer via capillary pores. Various active principles are available depending on the result needed, from a complete closure of the pores to pore hydrophobizing (Siliconate, Silicone Alcali silicate, Silane\/Siloxane, Acrylate gel\u2026).<\/p>\n
