Vibration isolation of a multi-storey single-family house

Several single-family homes have been built in the municipality of Bad Endorf, which are located in the immediate vicinity of a regional railway / suburban railway line.

The experts forecast high immissions from vibrations and secondary airborne sound and recommended an elastic building support with a tuning frequency of about 7 Hz.Calenberg carried out an economic strip-shaped (and not fullsurface) solution with the bearing type Cibatur®. The strips were placed on the foundations of the outer walls and under the loadbearing interior walls. Cibatur® provides over a very large load range constant low natural frequencies. Therefore the differently loaded foundation sections could be equipped with storage strips of the same width. Subsequently, prestressed concrete hollow slabs were placed on Cibatur® and the joints between the slabs were cast without sound bridges.
