Damp treatment à Machelen
Diagnosis and treatment of rising damp, penetrating damp and condensation. Machelen and Diegem call for two ways of working a few streets apart: single-family houses where the occupants are at home, and company buildings where the work cannot stop.
5 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.
Machelen and Diegem form a mixed fabric of residential districts and industrial estates. We work there on single-family houses as much as on warehouses and company flat roofs, with the organisation that goes with it: working outside opening hours and zone by zone.
What we get called out for in Machelen
Machelen and Diegem call for two ways of working a few streets apart: single-family houses where the occupants are at home, and company buildings where the work cannot stop. For the latter we plan zone by zone and outside opening hours; for the former, as anywhere else.
Machelen porte le code postal 1830 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 5 km : nous y planifions le traitement de l’humidité en même temps que les chantiers de Vilvoorde, Zaventem et Grimbergen, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Machelen se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 5 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Vilvoorde 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.
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.
Then no injection will change anything. Condensation is a matter of ventilation, heating and thermal bridges. We tell you so, even if it means we have nothing to sell — it still costs you less than a pointless treatment.
