To meet the demands from the contractor, Skanska needed new drill technology for reinforcing the foundations of a famous warehouse with underpinning.
A long-time landmark in the center of Turku, Sokos Wiklund warehouse building, needed a total of 200 holes to be drilled with casing in the underground parking hall. Additional corrosion reinforcement and concrete were then installed inside the 219.1/12.5 Ruukki casing tube. Due to space restrictions set by the site, a small drilling unit was used. Drilling with a ring bit casing system was the only alternative.
With Robit Casing System, the drilling was completed in a very short time. With such an impressive outcome, it was decided to introduce the system to several similar projects in the region.
