Long-Term Quality in a Historic Setting – ROMEX® RSG5 System Proves Itself in the Heart of Frankfurt
In the centre of Frankfurt, between the Römer and the Main River, lies the Historical Museum – an architectural landmark with historic significance. As part of the new construction, the museum’s inner courtyard was redesigned in 2017. The particular challenge: a vaulted cellar underneath the surface allowed for a maximum load of only 19 kN/m³. This sensitive base required a technically precise and reliable solution.
Tailored Project Consultation as the Key to Success
From the outset, it was clear that standard solutions wouldn’t suffice. ROMEX® experts provided comprehensive planning support to ensure the optimal combination of load-bearing capacity, flexibility and durability.
The choice: the proven ROMEX® Bedding and Jointing System “RSG5”, specially developed for sensitive substructures and demanding loads. The following components were used:
-
ROMEX® - TRASS BEDDING: for a low-stress, durable bedding layer
-
ROMEX® - BONDING SLURRY: to ensure secure adhesion between layers
-
ROMPOX® - D1 in basalt grey: our tried-and-tested synthetic resin joint mortar for heavily trafficked surfaces
Durability with System Guarantee
The RSG5 system is part of the ROMEX® SYSTEM GUARANTEE, providing a minimum of five years of technical assurance – a quality promise that exceeds industry standards.
Successful Reinspection After Seven Years
A recent site visit – seven years after project completion – confirmed: The surface remains in excellent condition. No settling, no damage, and no visible changes in the joints. The area still looks clean, stable and high-quality – a testament to the long-term performance of the ROMEX® system.
Conclusion: Engineering Meets Aesthetics – Sustainable and Reliable
The Historical Museum project in Frankfurt showcases how modern jointing technology and classical architecture can be seamlessly combined. With the ROMEX® RSG5 system, both technical requirements and design expectations were fully met – a true reference project.
