SSAB delivered 3 800 m RD400/12.5 piles for deep foundations in clay and hard moraine. RD piles are installed by drilling and are especially suitable for difficult ground and environmental conditions. Total of 3 800 m piles were installed with average pile length of 50 meters. Piles were delivered in 6 m, 12 m, 16 m, and 18 m lengths. They were manufactured specifically for the project in SSAB’s Oulainen mill. Piles were drilled through the so-called “Mjøs-moraine”, which can be extremely competent and hard. This is located around the Mjøsa region in Norway. There were challenging conditions for the drilling also due to large amount of water in the area from 25 m to 48 m.

Piling contractor Hallingdal Bergboring AS was pleased with the delivery. “We wanted piles from SSAB because of good tolerances and quality of the piles, which makes it easy to splice the piles at site. Short delivery time and good logistic was also important” says Marius Øen, Hallingdal Bergboring AS. Main contractor for the project is HENT AS and the owner of the project is AB Invest AS.
