Moisture problems have various origins, from roof leakage to capillary rise from the foundations. The traces are apparently all the same.
The right diagnosis, the right intervention
An observation of the moisture traces, the location of the damage and the probable external origin must allow you to identify the causes.
The diagram below will help you identify them and, most importantly, locate them.
Many of the problems can be easily solved without major work. For others (roofing, façade damage, hair rising), however, the use of a professional is necessary.
This analysis, pure logic, will help you to take the necessary measures:
- bring a bricklayer, roofer, plumber or moisture treatment specialist to deal with the problem;
- intervene yourself when you can.
• Stains appear on the walls or ceiling.
• The wallpaper is peeling off.
• The paint is flaking.
• Mold appears.
• Bad odors emerge.
• Saltpetre (whitish and powdery traces) and halos appear on the walls of the cellar.
• In which part of the house (basement, ground floor, floor), or rooms (under roof, bathroom or shower room) does the problem occur?
• On which part of the wall do you observe traces of humidity?
• In what circumstances did the problem occur: rain, storm, after plumbing, after using plumbing fixtures, or after finding a leak?
- Origin of the damage
• If cracks or breaks appear on the outside of the masonry or roof, these are infiltrations.
• If the phenomenon occurs in a heated room, where there is often water vapor (bathroom, shower, laundry, etc.), and one or more cold walls, it is condensation.
• If an appliance has overflowed, if a line leak has occurred, this is an occasional problem.
• If the phenomenon is located at the foot of the wall on the ground floor or on the basement walls, it is a matter of capillary rise.
The possibilities of intervention: The moisture absorber
The crystals in the tray absorb a small part of the ambient humidity.
Structural work are not your responsibility, but it is good to identify them to discuss with a professional and show him that you have clearly understood the problem that can be at:
- of the roof: tiles or slates displaced or porous, gutter leaks, loss of sealing of a terrace;
- masonry: disjunction between the roof and a masonry part, cracks at the bottom of the chimney stump, at the level of the facade, around a window;
- foundations: porosity, capillary rise, stagnation of water around the house due to poor drainage.
The resorption of certain phenomena is accessible to you (provided, in all cases, to have previously eliminated the cause of moisture).
You can for example:
- prevent the formation of condensation by better ventilating the room and avoiding the phenomenon of the cold wall by installing a thin insulation inside the room;
- ensure that the windows are in good condition, in particular by opening the water outlet (water jet) at the bottom of the frame (small hole in the center of the cross-member, visible when the window is open);
- make sure the joints of the sanitary appliances are watertight (the water infiltrating can reach another room);
- waterproof surfaces that have been moistened;
- place a moisture absorber in all rooms that are naturally damp and difficult to ventilate (kitchen, bathroom and shower room, cellar, etc.).
Injection of resins
The treatment of masonry and foundations goes through the intervention of professionals to achieve:
- sealing foundations from the outside;
- resins injection in masonry to form a sealing barrier;
- the casing interior of the basement or ground floor rooms of the building to block penetration and upwellings from the ground.
