Using a Powertool KRX 70 drive unit with milling attachment, recesses are made in bored piles, into which reinforced concrete spurs are poured at a later date.
Near Osterode in the Harz Mountains (Germany), the intake section of the Söse dam is being renovated. In the process, the holding dam had to be resealed using a new bored pile wall.
