Flat roof waterproofing à Machelen
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. 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, the flat roofs over extensions and garages are almost always under trees. A single blocked outlet turns the roof into a pond, and that weight of water forces the weak points. Balloon gratings and an overflow matter more here than the membrane itself.
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 l’étanchéité de toit plat 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 ; l’étanchéité de toit plat n’est chiffrée qu’ensuite.
Not always. If the deck is sound and the insulation dry, an overlay is possible and costs considerably less. We always probe the insulation: covering over waterlogged insulation means shutting the problem in for ten years.
Yes, and it is often the best first step. We locate the source, give you a time-stamped photo report and a quotation for the repair. Nothing obliges you to give us the work afterwards.
