Restoration of reinforced concrete at a sports ground in Bolzano

The grandstand at the Maso della Pieve sports ground in Bolzano was in a serious state of disrepair with the outer part of the precast reinforced concrete structures suffering most. The damage had been caused mainly by erosion due to freezing and carbonatation, and had begun to affect the reinforced steel bars of the stand.
Before beginning to restore the reinforced concrete, the whole structure underwent thorough mechanical cleaning in order to detach any loose concrete and to ensure an optimal fit between the old concrete substrate and the new applications.
The reinforced concrete was restored using ACS Ferri 1K, ACS Malta 1K and ACS Monorasante. In between the individual precast elements, the silicone sealant Sitol Silicon Basso Modulo was applied.
