PROJECT APPLICATION
THE FERENC PUSKÁS STADIUM IN BUDAPEST Waterproofing materials, resin floors and building solutions were provided for one of Hungary’s largest sports stadiums.
The Ferenc Puskás stadium was rebuilt and completed in 2019 and can now host 67,000 spectators.
The new stadium in Budapest, dedicated to the footballer Ferenc Puskás, is a monumental structure worthy of the legendary status of this Hungarian superstar. Rebuilding work on the remains of the old stadium, which started in 2017 and was completed in 2019, was one of the largest ever investments in Hungary for a sports complex - 190 billion Forints (around EUR 610 million) to build a stadium which has a capacity of 67,000 and which was used to host some of the 2020 UEFA championship matches. The stadium is made up of a structure with 38 fortymetre high, steel and reinforced concrete pylons. Two cement mixing units were installed directly on site to actually construct the load-bearing structure. Each cement mixing unit had a maximum daily output of 1,200 m3 of concrete. Every day, the site had a workforce of 1,500 and 21 cranes - all working at the same time.
Waterproofing at 360° Mapei played a key role in the construction of the new stadium, supplying products for various areas and applications. The products included MAPEFILL MF 610, 36

an expansive grout which was used to anchor the large pylons of the load-bearing structure. But it was in all the waterproofing applications that Mapei really made its contribution, by proposing specific solutions for each of the problem areas. For example, for the surfaces below ground level, that were exposed to water under pressure from the subsoil, and for the surfaces on the ground floor exposed to moisture from the ground, technology had to be employed that would guarantee good water-tightness, while forming a tough bond with the substrates. For this reason, for this part of the work, 10,000 m2 of surfaces were sprayed with PLASTIMUL 2K SUPER and PLASTIMUL 1K SUPER PLUS, two-component, solvent-free, highly flexible, low-shrinkage, thixotropic bituminous emulsions. For the reinforced concrete masonry below ground level, on the other hand, the preference was for PLANISEAL 88, a one-component, osmotic mortar, with good adhesion to the substrate, for complete waterproofing, even in the presence of negative pressure.
