One of the standout case studies featured in the IACDS Yearbook 2026 comes from Germany, where FINDEIS BETONBOHRSERVICE TB successfully completed the removal of two massive reinforced-concrete foundation blocks at a regional energy supplier’s plant.
At first glance, the project appeared to be a straightforward dismantling job, but, in reality, it required careful planning, specialised cutting techniques and a low-vibration approach to overcome a series of structural challenges.
The work, carried out between July and September 2025, involved the removal of approximately 150 tonnes of reinforced concrete from the foundations of a former coal mill. The foundations were mounted on spring elements, creating a “floating” support system that ruled out conventional demolition methods.
“Large demolition sections were expressly not permitted,” explains Managing Director Michael Findeis. “According to the concept, no larger pieces were allowed to be moved into the area where the wheel loader could handle the material. That made one thing clear: the components had to be divided into manageable segments of about one tonne each.”
Instead of using hydraulic breakers, the team relied on a combination of core drilling, wall sawing and wire sawing to dismantle the structures safely and with minimal vibration. The concrete blocks, each weighing around 56 tonnes, were cut into transportable sections and removed in a carefully coordinated sequence.
“The real challenge became apparent with the exposed foundations: both blocks were floating on their supports, and each rested on 20 spring elements,” says Michael Findeis.
Alongside the cutting operations, logistics and environmental management played a critical role. Concrete sections were continuously removed from the work area, while drilling and sawing water was collected, treated and disposed of in accordance with environmental requirements.
