Damp treatment à Zaventem
Diagnosis and treatment of rising damp, penetrating damp and condensation. In Zaventem it is striking how many enquiries concern what sits under the tiles.
9 km from our depot in Grimbergen
What that changes here
On the periphery damp often comes from outside and from above: an overflowing gutter, a failed flashing, a terrace built up too high against the facade. Our search always starts at the roof, not at the wall.
Zaventem lives with the airport: over the decades many houses have had extra insulation and acoustic work carried out in the roof. That work was not always done carefully, and we regularly find a crushed air gap or a missing vapour barrier.
What we get called out for in Zaventem
In Zaventem it is striking how many enquiries concern what sits under the tiles. Over the years many roofs have had an extra layer of insulation or acoustic work; we get called when damp gets involved. Alongside that, the ordinary work: gutters, roof windows and slopes at the end of their life.
Zaventem porte le code postal 1930 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 9 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Kraainem, Machelen et Wezembeek-Oppem, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Zaventem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 9 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Machelen, 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.
