Rising damp rises up from the ground and can be found in buildings where there is either no damp course present, or the damp course has become ineffective for any number of reasons. The damp course may have simply deteriorated, or it may have been bridged by the external ground level being built up, for example if a new patio has been laid or through debris collecting in the wall cavity.
Rising damp can be seen as tide marks appearing on a wall normally to a height of 1m. The tide mark or stain is generally caused by the chloride and nitrate deposits, known as hygroscopic salts, which are left in the wall and plaster when the dampness in the wall evaporates. The hygroscopic salts have the ability to attract ambient moisture and will therefore remain damp until removed and the wall re-plastered with a specialist re-plastering formula.
Penetrating damp is caused usually as a result of poor property maintenance for example defective and blocked guttering, defective plumbing causing overflows as well as environmental factors such as wind driven rain. Such damp can penetrate the structure of the building and can be the cause of internal adjacent timbers becoming damp and as a result degrading through dry rot and wet rot infestations.
Leaving damp problems untreated
Left untreated, dampness can and will spread throughout a property, becoming progressively worse in the form of timber decay, damage to brickwork and plaster and increasing the risk of dry rot and insect infestations.
