Solna Arenastaden right next to Solna railway station needed support piles for passage over railway between Arena and surrounding buildings. The urban site called for extra care and Robit products.
The work site needed some 150 piles (220/12.5) to be driven to overburden ground, which tends to ”suck the water” due to numerous fractions. What’s more, there was a large sewage passing near the worksite, let alone railway and buildings. In this environment, any pollution would be no-no as well.
Due to ground type, air drilling would almost surely cause problems to surroundings. The use of Wassara W150 ensured fast penetration and created less noise. The project was finished with minimum disturbance.
