  • Installation of a 33 m walkway by helicopter transport

To refurbish a pedestrian footpath, the Hydrokarst teams installed a 4-tonne, 33 m-long, 1.2 m-wide aluminium walkway.

Before the walkway was presented, special reinforced-concrete foundations were built with the use of micro-piles and pre-constrained ground anchors. The walkway was then lowered into position by helicopter. Our teams performed safety checks and final fitting of the walkway.
