Budapest, Hungary

Description:
Created in the first half of the 19th century, Budapest’s City Park (Városliget) Ice Skating Rink is Central Europe’s biggest. In the summer, the facility is converted into a lake for boat rides, festivals and other events. The renovation of the 16,800 m² ice-rink, the reception building and an unrestored wing of the old building, destroyed during WW2, prepared the facility for the 2012 European Speed Skating Championship. Extreme temperature differences (winter/summer, day/night) and the proximity of water to the concrete posed key challenges for the project. 

Products Used:
PENETRON ADMIX was used to waterproof the public utility tunnels, 4,000m³ of concrete exposed to about 1m of water on the lake side and 2.5-3.0m of ground water. The hairline cracks that developed during concrete hydration were completely sealed within days after ponding the slab.
