Drilled Piling

The appreciation for the quality of our work and for observing the schedule in the mine drilling projects was taken as a guideline also in drilled pile construction.

The Finnish soil is particularly challenging for all kinds of groundwork construction because of the complex soil with clay layers created by the ice age, gravel and moraine layers and the world’s hardest bedrock of the Scandinavian tectonic plate.

We became interested in piling because we could see the challenges drilling and piling machines were having with the Finnish soil and the weaknesses of driven piling on inclined terrains and deep strata. We wanted to test down-the-hole drilling also in foundation construction since it had been found a well-suited and effective means in well drilling.

The first test piles and test sites were made in 1996 when Sotkamon Porakaivo purchased its first machines that were designed only for groundwork construction. It was followed by a machine suited for anchoring and micro piling and in 2002 we acquired Bauer’s drilling rig equipped with a telescopic mast that became a pioneering machine in the whole of Scandinavia.

Drilled piling for groundwork construction

In drilled piling the underground steel pipe is driven through the strata to the desired depth in the rock. The steel pile is one of the supporting elements in the connecting construction of the founding pile. Drilled piling is applied in all groundwork construction when a quick and more importantly a secure foundation solution is desired. In drilled piling, the bottom end of the pile of drilled into pristine bedrock. As a foundation solution drilled pile is practically eternal and does not sink.

Promptly and precisely

The share of drilled steel pipe piles of all groundwork construction is soaring. Drilled piles are quick to install, it can be done very precisely to all kinds of soils and it is highly durable and does not sink.
