Flat Roof Renovation at a Car Dealership in Aachen

Planned, assisted, solved. The renovation of flat roofs—such as those on car dealerships or industrial buildings—is particularly challenging due to the large surface areas and numerous details, such as skylights, drainage systems, and parapet connections. Added to this are logistical challenges such as long transport routes, limited construction site space, and the need to work while operations continue.
For the maintenance of the roof surfaces at a car dealership in Aachen, those in charge therefore opted for a solution using Triflex. The Triflex ProTect waterproofing system, based on polymethyl methacrylate (PMMA), in combination with Triflex ProDetail, is exceptionally durable and can be efficiently applied using the Triflex SAM spray application machine.
