A new terminal and bus station are being built at Split-Kaštela Airport in Croatia. MAX FRANK Tubbox® "blowhole-free" column formers were used for the round columns for the bus station.
The two-storey bus station building has an overall length of 80 metres and a total width of up to 30 metres. The steel structure of the roofed footpath on the east side of the building is supported by circa 50 concrete columns.
The concrete columns are shuttered with MAX FRANK Tubbox® column formers in the "blowhole-free" surface finish option. Water-repellent Zemdrain® CPF liner, which lines the inside of the Tubbox® column formers, ensures a blowhole-free surface finish and increases the surface hardness of the concrete.
