After 5 years R&D, Dreamcutter Technology finds its first site on the Oosterweel project

After five years of intensive research, testing and refinement, the Cube System is being deployed operationally for the first time on a major infrastructure project. Within the Oosterweel Link project, Denys is constructing a complex slurry wall beneath the railway bridge at Groenendaallaan.

Innovating to improve quality of life

The development of the Cube System is rooted in Denys’ conviction that construction must do more than deliver infrastructure. It must contribute to a better quality of life. Driven by a strong R&D culture, Denys develops technologies that enhance safety, reduce environmental impact and make complex challenges solvable.

The Dreamcutter technology is a tangible result of this approach: a new way benchmark for underground construction, with quality, safety, sustainability and environmental impact at its core. The technology enables underground works to be carried out more safely while keeping surface disruption to a minimum.

From innovation to execution

On site, the Cube System is translated into concrete execution by Future Foundations, a subsidiary of Denys specialising in foundation techniques and complex underground construction, supported by its partner ICOP, a leading company in special foundation and underground works

Unique technology, a world first

The Cube System is the world’s first slurry wall machine with a total machine height of just 2.9 metres. The machine is the result of a collaboration between construction specialist Denys and equipment specialist Bauer Maschinen.

Thanks to the horizontal configuration of its key components, the system can operate where conventional slurry wall machines cannot be deployed in existing structures and urban environments: beneath bridges, in microtunnels, and in the basements of existing buildings.

First application: Oosterweel – lowered R1 North

For the construction of the new, lowered R1 North, Future Foundations, together with execution partner ICOP, is constructing a slurry wall measuring 142 linear metres in length and 30 metres in depth, extending 3 metres into the Boom clay, under a free working height of just 5.1 metres.

The wall serves as a water-retaining polder wall, essential for the dry and durable operation of the tunnel structures within the Oosterweel Link.

Smarter and more sustainable than conventional solutions

Where a jet grouting solution was initially considered, the Cube System offers a technically more robust, more durable and more watertight alternative, with lower maintenance costs and a smaller ecological footprint over the full design life of the structure (100 years).

Thanks to partners who dare to innovate

This first on-site deployment is the result of close collaboration between Denys, technology partner Bauer, Future Foundations (execution and underground expertise), execution partner ICOP, the partners within ROCO, and client Lantis.

“Oosterweel demands courage and innovation. By joining forces with partners and embracing new technologies such as the Cube System, Lantis can raise the bar in terms of safety, sustainability and livability within a complex urban environment.”
- Gert Osselaer, Director of Operations Lantis

The works started in early January 2026 and will continue until October 2026. The first five slurry wall panels have already been successfully milled and cast in concrete, marking the Cube System’s first deployment on site.
