Damaging moisture

Capillary rise can cause extensive damage in terms of material and equipment, unpleasant odours, and even respiratory diseases… Build4.0 identifies the cause of such damage by performing a free diagnosis, to help you eliminate the problem at its source.

Material symptoms

Damaging moisture: exterior Damaging moisture: Crumbling walls Damaging moisture: spreading of mould

By invading walls where salts and nitrates meet, humidity leaves traces on facades, as well as many inconveniences inside buildings:

  • Destruction of wall and floor coatings: blistered paintwork and tapestry, swollen baseboards and water-damaged wooden floors.
  • Crumbling walls, plaster and coating.
  • Decaying wainscoting (staircase, beams…), with the development of dried and rotten fungi.
  • Spreading of mould.
  • Appearance of saltpetre and whitish, fibrous deposit caused by mineral salts present in the water.


After experiencing both winter frost and summer vapour, water found in walls causes their slow but sure deterioration, sometimes to the extent of damaging a building’s very structure.

Smells caused by humidity

Fouled water in walls systematically increases the ambient air’s degree of humidity by evaporating into the room. As it increases the development of bacteria and appearance of mould, this ambient humidity is easily noticed by the unpleasant, persistent and characteristic smell it leaves behind.

Health hazards

Humidity presents serious health risks, standing as a trigger or amplifier of many diseases:

  • Respiratory disorders: chronic cough, rhinitis, bronchitis, asthma, pneumonia.
  • Allergic and immunological reactions: conjunctivitis, eczema, dermatitis.
  • Toxic reactions: sore throat and eyes.
  • Neurological reactions: headaches, vertigo, alertness and fatigue, depression.
  • Infectious diseases.
  • Rheumatisms, arthrosis.
