Besab first contractor ever to use the GDS Twin 720 diesel in connection to ground re-inforcement of the Pyramiden blocks

The Skanska Bostäder’s Pyramiden blocks on Södermalm in Stockholm is being re-inforced with water-propelled drilling technology and the unique Twin 720 diesel pump from GDS. This is, as 72 holes were to be drilled down to a depth of ~20 meter.

The GDS 720 Twin is a pump that can give up to 720 lit/min @ 190 bar. The unit can serve two rigs in parallel, each with a 4-inch hammer, with high pressure water. In this specific project, however, the 5-inch hammer WAI 50i from DrillKing was used.

The reason for using the water-propelled drilling technology was due to requirements on work environment, minimization of risk settlements as well as increased production.

Drilling finished ahead scheduled period of time.
