SSAB has finished the second phase of deliveries to Pasila Tripla, a massive billion-euro construction project near the city center of Helsinki in Finland. In the last newsletter SSAB’s extensive RD pile wall delivery of close to 4 200 tons of piles, totally 13 500 square meters, was presented. RD pile wall delivery started in May 2015 and after the installation was finished by mid November 2015 the deliveries continued with casing tubes for the anchoring until June 2016.

Finished RD pile wall meets all the demands

After the installation of the RD pile wall and excavation it is now evident that it meets all the demands excellently. RD pile wall complies with tight tolerances of installation and water-proofing. Finished wall is fully waterproof. Installation deviations are minimal and within required tolerances – wall is extremely straight without any leaking.
