How the Symmetric casing system manages to install piles for a new railway bridge in difficult ground in Stockholm, Sweden.

Work to drive piles into the canal bed for a new railway bridge faced delays when unconsolidated ground was encountered. The new foundations were to be built close to the existing bridge?s foundations and required a drilling technique that would cause a minimum of disturbance.


Working with drilling contractor, Terramek, Atlas Copco Rotex developed a customized Symmetrix ring and pilot bit. The new system proved faster and coped well with the unconsolidated ground, allowing completion of the piling phase

Epiroc operated under the trademark “Atlas Copco” prior to January 1, 2018.
