NATIONAL SOCCER STADIUM, BRATISLAVA
Kick-Off in Bratislava
Slovakia’s new National Stadium in Bratislava is located at the same site as its predecessor, but this new facility has a much more sophisticated drainage concept.
A three-cornered stadium
With capacity for 22,500 spectators, the newly built stadium is home to the Slovak soccer club ŠK Slovan Bratislava. It offers WiFi, security monitoring technology, and studios for television broadcasting. Condominiums, offices, a shopping center, and a hotel have also been integrated to enhance its utility and attractiveness. Situated next to the main grandstand, the hotel building forms one of the four corners of the stadium facility, which of course also has underground parking (996 spaces) and direct connections to public transportation.
A plateau of challenges
The stadium is now surrounded by a plateau structure for pedestrian and vehicle traffic where stadium visitors can gather, and it leads into the stadium. This road doubles as an access for police, fire department, and other security vehicles. The remarkable structure also doubles as a roof construction covering the parking lots and delivery driveways. It additionally plays a key role in the stadium’s emergency evacuation route planning, and all these factors together led to special requirements regarding drainage.
Clear evacuation routes
An emergency evacuation plan is only effective if the evacuation routes are not flooded by water, even with heavy rainfall. Pavol Leško, who planned the drainage concept for the stadium, paid special attention to details. His clever idea: to install a floor drain every two meters. Thus a total of 680 floor drains (and the same number of dirt traps) provide for surface drainage. Accumulating water is evenly channeled into seepage and holding layers, into the roof drains and ultimately right into the stadium’s retention system. But even with terrific functionality, design remains crucially important. The grates for the BG-Graspointner channels employed fit perfectly into the visual appearance of the paved roof construction.
Reinforcement on the sideline
Thought was given as well to the possibility of thermal expansion resulting from major temperature fluctuation. The channels were encased in concrete to protect them against the effects of excessive force exerted upon them through the layer of block paving. Attention was also given in planning and installation to ensuring the correct number and positioning of expansion joints.
One solution for everything: FILCOTEN HPC
This project required a flexible drainage concept, and thanks to our line of FILCOTEN HPC drainage systems, an answer was found to every challenge. Both BG-FILCOTEN tec and BG-FILCOTEN pro pro were installed on the plateau, and BG-FILCOTEN pro was used for the connecting roads, where greater load-bearing capacity is required. The ideal solution for the stadium’s bus stop was BG-FILCOTEN one: a single-piece channel with no grate that is especially low-noise when driven over by vehicles. Another advantage of the product is its ease of maintenance. BG-FILCOTEN light was installed on the connecting footpaths and in the shopping mall. In total, more than 2.400 meters of channels made of FILCOTEN HPC (High Performance Concrete) were laid.
Support during every project phase
We provided technical support on the entire drainage project and closely cooperated with the planning team to devise the best possible solution to meet every requirement. Pavol Leško:
