The challenge in this project was that there was no or very minimal fresh air supply in the cellar vault. Therefore, special care had to be taken to ensure the safety of the cleaning personnel.
A special hood was placed on the operators head, to which fresh air could be supplied through a hose. This meant that the work could be carried out without danger. By using the dry ice blasting technology, the walls and ceiling could be quickly and thoroughly renovated without leaving behind any annoying residues such as contaminated water, blasting media or chemicals. The dry ice turns into a gaseous state and evaporates immediately after impact on the surface.
Dry ice blasting is an efficient, gentle and non-abrasive cleaning technology, which is why it is popular for cleaning sensitive surfaces, among other things. Unlike conventional blasting methods (with sand or glass beads), the surfaces are not damaged or altered. Thus, the dry ice blasting process was the ideal and most effective solution for the renovation of the cellar vault in the Hotel Traube in Buchs.
