Stairways are characterized by a continuous transit of people, causing rumbling noises that often rebound on the adjacent rooms. In this context, Diathonite plaster is the ideal solution for sound insulation of partitions walls and to eliminate reverberation, typical factor in large spaces like this one. In the same way, Diathonite avoids heat losses from an heated room.

Often the stairway can be also adjacent to or surrounded by structures on ground level, or completely buried (underground); affected by water infiltrations in counterthrust. The use of waterproofing products resistant to negative hydrostatic pressure allows to encapsulate and eliminate these issues permanently.
