Intermediate Floor Filling at the Ferenc Puskás Stadium

At the Ferenc Puskás Stadium, on a more than 7,000 m² surface, the Energocell® granules were used as filling in the layer housing the utility installations. The architects have chosen the Energocell® foam glass because its water absorption capacity is very low - due to its closed-cell structure -, and the particles allow vapour-permeation, therefore in the event of pipe bursts or leakages the water would not become stale in the layer. The incorporated foam glass layers were 14-16 cm thick under the plumbing units, and 30 cm thick in other places. Given that the service installation pipes were laid in the foam glass layer, the use of hand rollers proved to be the most practical method for incorporation.
