In the Wunderstein®, Gerwing Steinwerke GmbH offers an innovative concrete paver from which even stubborn dirt can simply be wiped off. In addition, Gerwing guarantees a very high colour fastness that makes the stone look like new even years later. According to the company's managing director, Michael Gerwing, this is made possible by a completely newly developed triple protection in the core concrete, in the facing concrete and on the surface. Gerwing revised and optimised numerous processes in their concrete block production in order to achieve the desired result, which is now marketed under the name Wunderstein. There were 22 individual steps in total. One of them was the installation of a Quadrix system from Kraft Curing for accelerated concrete curing, which now ensures constant conditions for the curing of the concrete pavers the whole year round.
