To strengthen its position in the rapidly growing Stockholm construction market, Thomas Betong invested in a new flagship ready-mix concrete plant in Stäket, Järfälla, just outside Stockholm. Construction of the facility began in autumn 2024, and the plant officially opened in May 2025.
Thomas Betong is one of Sweden's leading suppliers of ready-mixed concrete and precast concrete solutions and is part of the family-owned Thomas Concrete Group. Founded in 1955, the company has nearly seventy years of experience in concrete production and today operates 38 ready-mix concrete plants and four precast factories throughout Sweden. Together with the Thomas Concrete Group, the company also operates in Germany, Poland, Norway, and the United States.
Thomas Betong has established a strong reputation for technical expertise, product quality, and sustainable concrete development. The company has been pioneering climate-improved concrete solutions for many years and continues to invest heavily in technologies that reduce the environmental impact of concrete production while maintaining the highest performance standards.

Extensive experience and a nationwide production network have made Thomas Betong one of Sweden's leading concrete suppliers.
The investment significantly increases Thomas Betong's production capacity in the Stockholm region while expanding its geographical coverage and improving delivery efficiency. The new facility also serves as the company's regional headquarters for Stockholm.
The Stäket plant has been designed as the most modern concrete production facility in the Stockholm area. It is capable of producing both today's and tomorrow's low-carbon concrete mixes using a wide variety of alternative binders, aggregates, and supplementary cementitious materials. The plant features numerous aggregate compartments and cement silos, providing exceptional flexibility for future concrete recipes and continuously evolving sustainability requirements.
Environmental performance has been a central design objective throughout the project. The plant incorporates a fully closed water recycling system, supports the use of recycled aggregates and concrete, and enables efficient production of climate-improved concrete with substantially reduced CO₂ emissions compared with conventional concrete production.

Multiple aggregate compartments and cement silos provide flexibility for both current and future concrete mix designs.
For its new flagship production facility, Thomas Betong selected the Tecwill Super Arcamix concrete mixing plant.
Super Arcamix is designed for large-scale, high-performance ready-mix concrete production where flexibility, production efficiency, and consistent concrete quality are essential. The plant combines high production capacity with extremely accurate weighing and mixing systems, enabling reliable production of demanding concrete recipes including modern low-carbon concrete mixes.
The plant supports many aggregate fractions, multiple cement and binder types, and various admixtures, allowing producers to rapidly switch between different concrete recipes while maintaining excellent production efficiency.
Recycled concrete from on-site crushing operations can also be utilized in concrete production.
The recycled concrete coming from crush plant can be also utilized in concrete production.

Super Arcamix combines high production capacity with precise weighing and efficient process control.
The new Stäket facility was designed to increase production capacity, improve delivery efficiency in the Stockholm region, and provide long-term flexibility for future concrete products. These objectives required a batching plant capable of producing large volumes of concrete while accommodating an increasing number of aggregate fractions, cement types, and supplementary cementitious materials.
The Super Arcamix plant provides the production flexibility needed for modern ready-mix concrete manufacturing. Accurate weighing systems support consistent concrete quality across different mix designs, while automated process control enables efficient production scheduling and repeatable batching accuracy.
The plant also supports Thomas Betong's environmental objectives. Precise material dosing contributes to optimized concrete mix designs and efficient use of cementitious materials, supporting the production of climate-improved concrete. The facility's layout further enables closed-loop water management and the use of recycled materials as part of normal production.
Operational reliability was another important consideration. The plant was designed for continuous commercial production with minimal maintenance interruptions, supporting dependable concrete deliveries to customers throughout the Stockholm region.
The flexible production system enables future adoption of new materials and concrete mix designs.
The new concrete plant in Stäket represents an important investment in Thomas Betong's production network in Sweden. The facility increases production capacity in the Stockholm region while providing the flexibility required for future developments in concrete technology and environmental performance.
By supplying the Super Arcamix concrete mixing plant, Tecwill contributes to a production facility designed for efficient concrete manufacturing, consistent product quality, and reduced environmental impact. The project demonstrates how modern batching technology supports the production of low-carbon concrete while maintaining the operational reliability required for large metropolitan construction markets.
