The Jakobsberg Nature Resort, located high above the Rhine near Boppard in the Upper Middle Rhine Valley, has undergone extensive modernisation and will reopen in mid-May 2026. Surrounded by forests, vineyards, and castles, the resort offers 86 modern rooms and suites with an impressive view of the Rhine loop and combines nature, relaxation, and regional culture. A special highlight is the 18-hole championship golf course with spectacular views over the Rhine, Westerwald, Taunus, and Hunsrück.

As part of the renovation, the PURE ELEMENTS Spa was created. Covering 1,264 m², it features an indoor and outdoor pool, saunas, a steam bath, massage and beauty treatments, and a fitness area for holistic relaxation. As a design element, aesthetically appealing, textured concrete partition walls were installed, produced by Betonwerk Heinrich Hachmeister Andernach GmbH, a specialist in architectural concrete and individually manufactured concrete components with high design standards. A decisive factor was the precisely developed surface structure combined with a uniform, low-porosity fair-faced concrete finish.

Concrete admixtures for high-quality fair-faced concrete surfaces

To meet these requirements, Hachmeister used specially coordinated concrete admixtures from MC-Bauchemie during production. The high-performance super-plasticiser MC-PowerFlow evo 306 was used, enabling excellent flowability and workability of the concrete. This allows the concrete to be evenly distributed and compacted even in complex, structured formworks. In addition, Centrament Surface Pro, a special admixture designed to improve concrete surface quality, was applied. It reduces pore formation and supports the production of particularly uniform and high-quality fair-faced concrete surfaces. The combination of both admixtures enabled a stable concrete mix design that ensures both good workability and a low-porosity fair-faced concrete appearance.
