Kerakoll’s Italian expertise
Enter the world of Kerakoll, an Italian company where ancient techniques perfected by the Romans to preserve buildings are still respected. Kerakoll offers a revolutionary solution to these problems, combining tradition with innovation.

The distinction
Rinzaffo vs Zoccolatura: Kerakoll’s approach involves a product system centered around Biocalce Rinzaffo and Biocalce Zoccolatura. Rinzaffo, a preparatory layer, prepares the walls for the main act—the Zoccolatura. Zoccolatura is where the real magic happens, thanks to its unique properties.

The microporous magic of Zoccolatura
Zoccolatura, a natural hydraulic lime-based render, is designed with micropores. These pores prevent water from entering while allowing water vapour to escape, so salts crystallize harmlessly within the wall. This property is crucial for protecting buildings such as the iconic Buda Castle and the rustic cellars of the Castle District.

Overcoming the shortcomings of cement
Commonly used cement-based mortars are notorious for contributing to SBS and damp-related problems because they react poorly with water. Zoccolatura, by contrast, highlights its lime-based composition and prestigious NHL 3.5 classification, symbolising outstanding quality and moisture management.

The Anstett test revelation
According to the Anstett test, Biocalce Zoccolatura shows just 0.8% expansion when exposed to water, in stark contrast to the 40% expansion of ordinary cement and the 30% expansion of ordinary lime. This property makes it exceptionally suitable for Budapest’s historic buildings, where interaction with water is unavoidable.

The Biocalce system – a symphony of solutions
The Biocalce system is a range of products, each playing a crucial role in wall renovation and preservation. From the Rinzaffo preparatory layer to the protective Zoccolatura layer, complemented by products such as Biocalce Tinteggio and Biocalce Fondo, the system offers a holistic approach to combating moisture and rising damp.

Prestigious WTA certification
Both Zoccolatura and Rinzaffo boast WTA certification, demonstrating their effectiveness and reliability in preserving the health of buildings, whether on façades along Andrássy Avenue or in the interior spaces of the Parliament Building.

Versatility Inside and Out
Uniquely, this Kerakoll solution can be used both inside and outside buildings, offering a versatile approach to preserving Budapest’s architectural wonders, from the grandeur of the Opera House to the quirky charm of residential buildings.

Conclusion
As Budapest continues to embrace its historical roots while looking toward a sustainable future, solutions such as the Kerakoll Biocalce system play a crucial role. They bridge the preservation of the past and the protection of the present, ensuring that the city’s architectural gems continue to stand tall—not merely as reminders of history, but as healthy, vibrant spaces for people. In the heart of Hungary, Kerakoll’s innovation is more than a product; it is a guardian of heritage and well-being.
