Efficient precast production for Winkelmann Group

The new production facility covers an area of 44,000 m² and, in addition to the production hall, also includes an assembly hall and a logistics warehouse. The complex is complemented by a modern car park and a comprehensive infrastructure with roads, paths and green areas. The general contractor MH Invest commissioned STRABAG Pozemné staviteľstvo s.r.o. with the production of all precast concrete elements such as columns, beams, girders, purlins and binders as well as walls and foundation beams. Between May and September 2024, a total of 6,000 m³ of precast elements were produced, including large binders up to 34 m long and with a volume of 17 m³.

The challenges: time pressure and high-quality requirements

Several challenges had to be overcome during the production of the precast concrete parts. On the one hand, a high surface quality had to be achieved to fulfil both the visual and functional requirements. On the other hand, the production process had to be optimised to ensure the rapid manufacture and assembly of the prestressed precast concrete elements. These framework conditions required a reliable and efficient solution.

High-performance products from MC for optimised processes

To fulfil the high requirements, Strabag relied on proven products from MC-Bauchemie. The PCE-based concrete admixture MC-PowerFlow 3131 VMA ensured optimum workability and high early strength of the concrete. This accelerated the demoulding of the components and made the entire construction process more efficient. In addition, the high-performance release agent Ortolan Premium 702 was used to ensure perfect surface quality. Thanks to its special formulation, bubble formation was reduced and a homogeneous, flawless concrete surface was achieved. This successfully fulfilled both technical and visual requirements.
