Water-repellent treatment & coating à Brussels
Clear or coloured water repellent for porous tiles and facades. In the City of Brussels half the work is done before anyone goes up onto the roof.
10 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.
The City of Brussels runs from the Pentagon to Laeken and Neder-Over-Heembeek: medieval plots with very narrow, very tall houses, 19th-century town houses with concealed box gutters, and further out post-war blocks with flat roofs. On a single job you come across everything — except room to work.
What we get called out for in Brussels
In the City of Brussels half the work is done before anyone goes up onto the roof. Access, permits, occupation of the pavement, the managing agent’s approval: that route sets the schedule. Technically it is most often box gutters, upstands against the neighbouring facade and extension flat roofs — rarely a complete slope.
Brussels porte le code postal 1000 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 10 km : nous y planifions le traitement hydrofuge en même temps que les chantiers de Molenbeek-Saint-Jean, Schaerbeek et Ixelles, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Brussels se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 10 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Molenbeek-Saint-Jean ou Schaerbeek, 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.
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.
Applied properly on a clean, dry surface, allow eight to ten years on a roof and five to eight years on a facade exposed to westerly rain. The first sign of wear is easy to spot: the water no longer beads, it spreads out and darkens the material.
