In terms of DSO, the space of underground garages very often does not meet the reverberation requirements. The same applies to stairwells. On this project, both of these spaces required acoustic adaptation. One of the more economical and quick-to-implement ways to improve this situation is to spray Sonaspray® ECO acoustic plaster.

Due to the low ceiling and, very often, a small number of sub-ceiling installations, this is one of the more graceful planes to perform. The pace of work in our case usually oscillates even between 200 and 400m2 per day. The effect can be heard immediately. A great alternative to installed lamella wool. The same applies to staircase landings.
