Water-repellent treatment & coating à Anderlecht
Clear or coloured water repellent for porous tiles and facades. In Anderlecht the conversation depends on the district.
12 km from our depot in Grimbergen
What that changes here
On a Brussels roof slope a water repellent adds little: the slopes are small, often in natural slate, and the real leak is in the box gutter. We advise against it here most of the time, and we say so. On the concrete tiles of the post-war districts in Evere or Anderlecht the conversation is different — there it is justified.
Anderlecht is the largest of the Brussels municipalities, and therefore the most mixed: dense 19th-century workers’ housing in Cureghem, commercial buildings with large flat roofs along the canal, and villas with gardens over towards Neerpede. Three ways of working in one territory.
What we get called out for in Anderlecht
In Anderlecht the conversation depends on the district. In Cureghem it is dense terraced building, shared walls and access to the rear. Along the canal, large flat roofs on warehouses and workshops where the work cannot stop. And in Neerpede, ordinary house roofs surrounded by garden.
Anderlecht porte le code postal 1070 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 12 km : nous y planifions le traitement hydrofuge en même temps que les chantiers de Forest, Molenbeek-Saint-Jean et Brussels, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Anderlecht se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 12 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Forest ou Molenbeek-Saint-Jean, 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.
