Water-repellent treatment & coating à Wezembeek-Oppem
Clear or coloured water repellent for porous tiles and facades. In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life.
13 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.
Wezembeek-Oppem continues on from Kraainem and Woluwe-Saint-Étienne: quiet districts, wide plots and many roofs from the 1960s and 1970s. It is typically the area where a roof is not broken but finished: the tiles have become brittle and the ridge tiles have worked loose.
What we get called out for in Wezembeek-Oppem
In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life. The tiles of the 1960s and 1970s have become brittle, the ridge tiles have worked loose and the roofing underlay — where there is one — has gone hard. It is not an emergency, but it is a conversation better not put off for five years.
Wezembeek-Oppem porte le code postal 1970 et se situe in the eastern periphery of Brussels. Notre équipe part de Grimbergen, à 13 km : nous y planifions le traitement hydrofuge en même temps que les chantiers de Kraainem, Woluwe-Saint-Lambert et Zaventem, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Wezembeek-Oppem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 13 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Woluwe-Saint-Lambert, 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.
