The existing roof had already been renovated by Tectum DSB in 2016. However, in light of the site’s further expansion and optimization, another renovation was necessary.
The original structure consisted of a steel sheet, a vapor barrier, rock wool insulation, a PVC layer, a separation layer, and a bituminous waterproofing membrane. This structure was thoroughly analyzed and optimized to meet current requirements for insulation value, durability, and energy performance.

Tectum Group carried out Tectum Group comprehensive renovation of the flat roof at D’Ieteren’s Porsche facility in Drogenbos. This project is part of a broader long-term strategy in which D’Ieteren is structurally optimizing its real estate portfolio, both technically and in terms of energy efficiency.
The site, located along the Grande Route in Drogenbos, is a key link in the D’Ieteren network. A high-performance, reliable roof is essential here to ensure business continuity.

An important part of the project was the planning and installation of a photovoltaic system.
The choice of a white roof finish plays a crucial role in this:
In this way, the roof actively contributes to the site's energy efficiency.
This project is part of a long-standing partnership between D’Ieteren and Tectum Group has been in place for over 30 years.
As part of this partnership, Tectum Group is Tectum Group for:
This integrated approach ensures continuity, clarity, and peace of mind.
With the renovation of the Porsche Drogenbos roof, D’Ieteren once again has a sustainable and high-performance roof that fits perfectly with the site’s overall renovation. The new roof structure provides a reliable and energy-efficient foundation for the building’s continued operation and is fully prepared for future applications such as solar panels. This project illustrates how a well-thought-out roofing approach contributes to the quality, sustainability, and future-proofing of a fully renovated building.
