Damp treatment à Leuven
Diagnosis and treatment of rising damp, penetrating damp and condensation. Leuven brings us two kinds of client: private owners on the edge of the city, and managers of subdivided buildings in the centre.

What that changes here
In old town houses the three causes often come together: rising damp in the cellar, penetrating damp through a tired joint and condensation in a poorly ventilated bathroom. We tell them apart by measurement rather than treating one at random.
Leuven is a student city with a historic centre and a great many subdivided buildings. That gives very varied roofs within a few streets: protected facades in the centre, terraced houses with small dormers, and at the back a forest of flat roofs over extensions that are rarely maintained.
What we get called out for in Leuven
Leuven brings us two kinds of client: private owners on the edge of the city, and managers of subdivided buildings in the centre. With the latter, the flat roofs over the extensions and the valleys between two buildings come back again and again — precisely the places that get forgotten when a house is divided up.
Leuven porte le code postal 3000 et se situe in the Dyle valley. Notre équipe part de Tienen, à 18 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Wezembeek-Oppem, Zaventem et Overijse, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Leuven se fixe en général sous quelques jours ouvrés. Nous partons de Tienen, à 18 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Wezembeek-Oppem ou Zaventem, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le traitement de l’humidité n’est chiffrée qu’ensuite.
By its height and its regularity: a horizontal band eighty centimetres to over a metre high, even along the whole length of the wall, often with salt efflorescence and plaster coming away. If the stain appears after rain and sits higher up, it is penetrating damp.
It works well on solid masonry with an accessible joint. On a cavity wall, in natural stone or filled with rubble, it is trickier, and another approach is more honest. We say so beforehand, rather than injecting and hoping.
