Walkable flat roof

The conventional flat or inverted flat roof, where the desired slope is achieved using inclination concrete.

The advantage of the conventional flat roof system is that the waterproofing bitumen strips can be heat welded directly onto the concrete inclination layer. Its disadvantage, however, is the inclination layer's heavy load and higher thickness. As a rule, the inclination concrete must be at least 5 cm thick at the drain. In the more contemporary OPTIMO system, inclination thermal insulation boards are used instead of the heavy concrete.
