Protecting
buildings fromvibrations
From opera houses in the midst of rumbling traffic to homes and offices alongside underground and tram lines, individual vibration solutions from Getzner
provide buildings with a highly efficient
form of decoupling and protect against
disruptive shocks and vibrations. Solutions based on polyurethane materials developed by our own experts
ensure peace reigns inside buildings,
thereby improving the quality of lifeand providing a more civilised workingenvironment.

Growing rates of urbanisation are resulting inever more new buildings springing up on plotsof land that are susceptible to vibration. The vibrations frequently emanate from nearby railway
lines, roads or adjacent industrial complexes. Unless appropriate action is taken, these buildings
are defenceless against the structure-borne noise
generated in their immediate environments: unwanted and occasionally even unacceptably severe
vibrations are the result. Secondary airborne noiselevels also rise, as the vibrations excite elements
such as the walls or ceilings. External factors suchas these have an unfailingly adverse effect on theliving and working environment inside the building.

Getzner Werkstoffe offers highly effective protection against shocks and vibrations. Our solutions
boost the value of buildings and land. Successfulprojects, including the Central & Park Panorama
Towers in Munich's Arnulfpark, serve to demonstrate that even buildings constructed immediately
next to busy railway lines can meet the most stringent requirements.

Benefits of a Getzner vibration
solution— Proven protection against
vibrations in buildings—	Reduction in sound radiation enteringbuildings from external sources (railtraffic, industrial complexes, roads)—	Higher quality of living and working
environments through elastic
decoupling—	Increase in market value of landand buildings—	Pioneering and lasting solution for
maximum comfort

against Shocks and Vibrations

Aplanner's task is not only to construct abuilding that complies with the relevant
regulatory standards, but also to meet theparticular requirements of the customer. The
diverse range of parameters with a vibration
isolation dimension have to be collated andimplemented according to the defined goals
and objectives. This is where Getznercomes in.

Source isolation is generally the more efficient approach. However, as many projects
involve sources that cannot be isolated
retrospectively, Getzner offers effective
yet affordable solutions for isolating therecipient against vibrations.

>> Involving experts earlycuts costs. The best
vibration protection isdevised during the planningstage. <<Recipient and source isolation
In the vibration engineering industry, a distinction is made between recipient isolationand source isolation.
—	Source isolation describes measures taken
at the source of the vibration (i.e. railway
lines, roads, industrial facilities). Examples
include elastic measures implemented on
the rail superstructure or decoupledmachine foundations.
— Recipient isolation is a solution that
decouples a structure from surroundingvibrations directly at the point where theimpact is felt. This is where the elastic
bedding of buildings is used.

Appropriate measures
for reducing vibrations

Full-surface bearingsfor buildings

Strip bearingsfor buildings

Getzner materials combine all
the properties needed to provide effective elastic shielding ofbuildings.

—	Easy to shape and install—	Achieves lower natural
frequencies—	Relatively little subsoil
preparation—	No changes to the building
design needed— Bearing on strip foundations—	Ability to implement vibration
decoupling between the individual
floors of a building— Lower material costs—	Achieve very low natural
frequencies

Example: Central & Park Panorama
Towers, Arnulfpark, Munich (DE):

Example:Linz Music Theatre (AT):

Requirement: Protect a building
constructed on a plot with pressurised groundwater from the vibrations
caused by a busy light rail line

Requirement: Elastic shielding between
the first and second basement levels

With Sylomer® and Sylodyn®, planners
have at their disposal technical elastic
bearing materials that permit a varietyof different designs.

Solution:—	Anti-vibration layer between thebinding layer and the building
foundation—	Architectural measures to transfer loads
to bearing strips or individual bearing
points are not required
Result:—	Proven effectiveness, even inpressurised groundwater—	Limited structural vibrations in
the foundation slabs due to thecontinuous support surface

6Solution:—	Decoupling through strip-shaped
dividing planes on the wall elements— Ceiling of first basement level directly
mounted on elastic strips
Result:—	Cost-effective vibration protection—	Prevention of sound bridges—	Disruption-free use of decoupledpremisesPoint bearings forbuildings

Side wall decoupling

Slot wall—	Bearing on discrete foundations—	Elastic bearing in the case ofdiscretely supported ceilings—	Provides vibration isolation ofbuildings on pile foundations—	Very low natural frequencies
possible—	Side wall decoupling from theground combined with full-surface,strip or discrete bearing—	Also suitable for shielding
in groundwater—	Retrospective installation on
existing buildings possible—	Vibrations are intercepted
before impacting on thebuilding—	Vibration protection
implemented duringrenovation work

Example:Helsinki Music Centre (FI):Example:The Touraine, New York (US):

Example:Paris Clichy Batignolles (FR):Requirement: Vibration isolation ofbroad-spanned ceilings on pillars

Requirement: Vibration protection fora residential building in the immediate
vicinity of three underground railway lines

Requirement: Vibration isolation ofinvestment property to protect against
vibrations from the adjacent railway lines

Solution:—	Elastic shielding of thebuilding's foundation—	Full-surface bearing for thefoundation slabs and side walls
right up to ground level

Solution:—	Installation of an elastic slot wall—	Consideration of the different
soil parameters—	Special material selection due
to the foundation pressure

Result:—	Total decoupling from thevibration source—	Maximum living quality in theimmediate vicinity of undergroundrail tunnels

Result:—	Vibration protection for neighbouring residential areas—	Higher property values ofneighbouring plots and future
constructions

Solution:—	Discrete decoupling—	Use of Sylodyn® HRB-HS
to bear higher loads
Result:—	Building load is borne byindividual discrete bearings—	Vibration isolation createsa quiet auditorium—	Cost-effective vibration protection
