A major rockfall incident occurred within the Tempe Gorge section of the Thessaloniki Highway in December 2009.
Geo-Design (UK) provided support to Geo-Design (Thessaloniki), who had been appointed as technical advisor to the Public Prosecutor to review and investigate the causes of the rockfall.
The investigation included a review of the engineering studies of the slope protection measures and the effects of blasting of nearby underground engineering activities.
