Project

Smulders Head Office South

Flat roofs

The roof structure consists of a vapor barrier, PIR insulation, and a two-layer bituminous waterproofing membrane. A particularly noteworthy technical feature is the integration of a horizontal Geberit Pluvia system. This system operates on the principle of negative pressure and ensures efficient drainage of rainwater.

The roofing work near the connecting bridge posed an additional challenge and required the necessary safety measures.

In addition, careful material planning played an important role. Because the crane was not available for the entire duration of the project, all necessary materials had to be accurately calculated in advance and delivered to the roof on time. Thanks to this preparation, our crews were able to continue the work efficiently without the need for additional hoisting operations.
