The source of damp problems

A correct diagnosis of damp causes is the first step to find a solution. Damp may be caused by condensation (environmental humidity), capillarity (rising damp) or lateral infiltrations (basements, cellars, underground homes, garages...).

MURPROTEC offers definitive and guaranteed solutions for dampness. Without any cost or commitment, our specialists will help you to identify what type of damp problem affects the walls and ceilings of your house and the most adequate solution to solve it and eliminate it once and for all.


Normal daily activities at home (showering, cooking, washing and drying clothes, etc) and a deficient ventilation produce condensation problems. Mould spots appear in walls or ceilings and, eventually, they could generate health problems.

Excessive environmental humidity may be the cause for damp due to condensation. This water exceed in walls and ceilings at the home encourages the growth of mites and fungi, increasing the risk of suffering allergies, asthma and other diseases related to damp.


Dampness moves upward through the foundation by the effect of capillarity and porous materials such as joints or bricks. The humidity evaporates in walls, saltpetre appears and coverings cracked including anti-damp paint.

Capillary rising damp may weak foundation and building walls, increasing the risk of building instability. Additionally, energy costs in houses that suffer this problem, are much greater, and suppose more spending to owners's of affected homes.


In basements, garages or homes built below the ground level, damp problems may appear when water present in the moist ground laterally leaks and penetrates inside the home. Lateral infiltrations pose a serious risk to the structural strength of the building.

Damp caused by lateral infiltration poses a serious threat to the security and stability of the building. Architectonical materials may detach due to structural dampness and it may derive in short circuits or fires when the affected wall has an electrical installation.
