The Proliner enabled Kalenborn Naturstein to find technically sound solutions to a complex cathedral restoration!

Since 1964, Kalenborn Naturstein has operated in Rieden, a municipality within the district of Mayen-Koblenz in Rhineland-Palatinate, western Germany, offering a single-source approach to natural stone services, from extraction to processing and installation. Natural stone is one of the company’s core competencies and they utilize the latest systems, machines, and qualified specialists to achieve the best results.

Their attention to detail as well as expertise in their industry, has earned Kalenborn Naturstein an excellent reputation in monument preservation and restoration. For a decade already, they have been using the Proliner Stone Package, taking the next step in technology and allowing them to achieve the highest level of accuracy, speed, and detail detection.

Peter Kalenborn told us about their recent projects, involving the restoration of a Cathedral in Aachen:

“We have worked on this project for years.  The restoration of this Cathedral in Aachen has meant a lot to us. It was a challenging construction site, with a lot of complicated details, but with the Proliner we were able to find technically sound solutions in conjunction with the other manufacturers. Without the Proliner, we wouldn’t have achieved the same results.”
