We recently reported that construction work on the new swimming pool in Sopron is progressing according to schedule, delivered by West Hungária Bau Kft. and Fertődi Építő Zrt. The development of the Csík Ferenc Swimming Pool, located on the site of the city beach, is being implemented within the framework of the Modern Cities Programme (MVP), with the products of MEVA Zsalurendszerek Zrt. providing significant support for the construction works. Mihály Botta-Dukát, Managing Director of the company, provided our publication with details on the project.
On the construction site, the formwork for approximately 8,150 square metres of reinforced concrete walls was built using the 3-metre-high elements — typically measuring 300 × 250 cm — of the large-panel Mammut 350 wall formwork system.

With its load-bearing capacity of 100 kN/m², the Mammut wall formwork system ensured a reduced number of tie points and a neat pattern of impressions and joints in the case of the watertight reinforced concrete walls. The plastic formwork facing used in the formwork elements withstood the surface effects caused by repeated installation and concreting, and is capable of delivering the same high-quality exposed concrete finish over an extended period of use.
Leier’s grandstand elements and civil engineering elements were also used during the construction works.
The Pool Walls Presented a Challenge
The side walls of the pools, with their complex geometry, were also built using the Mammut 350 system, but with smaller-sized elements.
“When designing the formwork, our primary objective was to ensure that the formwork followed the geometry of the pool wall as closely as possible, while minimising the amount of custom timber blockouts required. Where this was not possible, the contractor used prefabricated wooden boxes placed within the formwork,” Mihály Botta-Dukát explains regarding the application technology.

The formwork for the curved staircase walls was built using MEVA’s newly developed RADIUS formwork system. The formwork features a perfectly bendable steel facing that can be shaped into an arc, and one of its major advantages was that it required no on-site pre-assembly. The contractor set the radius using a template, after which the formwork elements were connected to one another and the formwork was completed quickly.
The monolithic reinforced concrete slabs, covering a total area of approximately 4,300 square metres, were constructed using MEVA’s MevaFlex timber-beam slab formwork. “We provided a layout drawing for the formwork design, thereby supporting the contractor’s work,” the Managing Director adds.
Circular Columns Give the Building an Impressive Appearance
The 42-metre-span glued laminated timber roof structure is supported by a total of eight reinforced concrete circular columns, each 13.5 metres high and measuring 50 and 80 cm in diameter. The circular columns were formed using MEVA’s steel-jacketed CIRCO circular column formwork, with a load-bearing capacity of 120 kN/m². The 13.5-metre-high columns were completed in two formwork stages with continuous concreting.
The building contains a total of 90 such circular columns, creating an impressive visual effect.
For the reinforcement works and the assembly of the column formwork, the contractor used MEVA’s MT60 scaffolding system, whose working platforms enabled the works to be carried out safely. The tower assembled from the scaffolding system could be easily moved from column to column by crane, providing cost-effective support for the ongoing formwork and concreting works.

The new indoor swimming pool will include a 25-metre-wide and 50-metre-long pool suitable for hosting international competitions, as well as a 25 × 25-metre pool, a warm-up pool and a teaching pool. In addition, a sauna, jacuzzi and fitness room will be created alongside the changing rooms.
A two-storey entrance hall will also be built as part of the facility, providing access to the spectator stand with 1,300 seats
