Water-repellent treatment & coating à Machelen
Clear or coloured water repellent for porous tiles and facades. 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
Under trees a water repellent makes little sense if the roof is covered in leaves again within the year. We only apply it after a full clean and a clearing of the surroundings, and we say plainly that it does not replace the annual gutter maintenance.
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 hydrofuge 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 hydrofuge n’est chiffrée qu’ensuite.
The clear product changes nothing about the appearance: it is the default choice, and the only one allowed in a protected area. The coloured product evens out a covering whose colours have drifted after successive repairs. It does not rescue a covering at the end of its life — it disguises it, and we will tell you so.
On a porous brick or render, yes, and it is often the cheapest way to stop damp coming through a west-facing gable. The condition is the same: a clean, dry surface, and the cause dealt with first — an overflowing gutter, for example.
