Project scope • Drilling for ground stabi- lization for light rail line, for minimization of vibra- tions in the ground • Number of holes: 160 • Depth: 18-25 m (59-82 ft.) • Scope of drilling/total meters: 3 440 m (11 300 ft.) • Why water-propelled drilling? With air drilling the surrounding sensible buildings and cars would have been damaged.

gds geo drilling solutions ab

Equipment• Hammer model/sizes: WAI 60i• Casing system: Symmetrix system with Ruukki

RD Ø220 x 12.5 mm drilled steel casing piles• Pump: GDS 490 Diesel Pump, 490 lit/min @ 200 bar• Water source: Water hydrant• Drill rig: SPD DT145• Geologic formation: Sea bed, thin layer of moraine, solid rock

Main stakeholders• Commissioner: SL• Main contractor: Svevia• Sub-contractor: Foundation Drilling Sweden

Project/drilling resultsThanks to the water-propelled drilling, the project was realized without unnecessary costs for covering the surrounding house façades and without risking surrounding cars in car park to be affected.
