Description of the project The solution
As well as training athletes’ muscles, thrusters, deadlifts and otherexercises often also put strain on thestructure of the building, and on theneighbours’ nerves.
Falling weights can cause noise disruption and can also damage thefloor. This can be a serious problem
for gym and CrossFit box managers.

The owners of the Reebok CrossFit
box in Zurich are only too familiar with this issue. The CrossFit box,located in a multi-purpose building at
Hardstrasse 81, 8004 Zurich, is oneof the best-known and most popularboxes in Switzerland. Even though theCrossFit box is in the basement of thebuilding, vibrations caused primarily
by weights being dropped are transmitted to the floors above and are radiated as disruptive noise.
The box owners had to look for a fast,efficient and highly effective solution
to this problem in order to ensure they
could continue to co-exist peacefully
with their neighbours.

Bearing of the 220 m2
free weights areaT

he solution chosen for the box’s
220 m2 free weights area was thehigh-tech elastomer g-fit Shock Absorb
from Getzner, which was picked for anumber of reasons.
Highly effective protection against
noise
The priority was to reduce the shocks
and vibrations caused by the extreme
forces resulting from training weights
being dropped on the existing sports
floor. This can either be achieved bydecoupling the floor with a floating
screed, or by using damping materials
that absorb the shocks.

In the case of Reebok CrossFit Zürich,
it was not possible to install a floating

screed retrospectively to the existing space. This solution would haverequired significant reconstruction
work, would have incurred high costs
and would have required the box toclose for a long period of time. For
these and many more reasons, thedecision was made to use g-fit Shock
Absorb (Advanced), a maximum
damping high-tech elastomer developed specially for weightlifting andfree weights areas.
The advantages of the solution
When using g-fit Shock Absorb there
is no need to make any additionalchanges to the floor, so the bearing
can easily be fitted retrospectively.
The low installation heights mean thatit can also be installed easily during

g-ﬁt Shock Absorb signiﬁcantly reduces
noise and vibrations caused by dropping
weights and free weights.
Feedbackrenovation works. Furthermore, theg-fit Shock Absorb significantly reduces the risk of injury to athletes as a result of weights springing back, and thereduction of the forces acting on thebase layer underneath in turn protects
the floor covering.

The maintenance-free g-fit bearings
therefore also help retain the value ofthe building, as there is less strain on
the building structure thanks to thecushioned shocks.

Value retention of the fabric of thebuilding

Another decisive factor is time: longclosure times impact the box’s business operations.
In the Reebok CrossFit Zürich box, theentire floor covering took just one day
to install. Customers can also decide
if they would prefer to install the newsystem themselves or if they wantto leave it up to the expert team atGetzner.

Data shows that in addition to theacoustic and vibration-related improvements, the impact of forces on
the base layer can also be reduced by
up to 75 %. This is particularly important for rental properties with existing
floor coverings. In buildings that havebeen used as gyms, floor coverings inweights areas must generally be replaced or repaired.

Time-saving, simple installation

Reebok CrossFit Zürich made the rightdecision by choosing Getzner.
“The g-fit Shock Absorb bearings
significantly reduce noise and vibrations caused by dropping weights andfree weights. For us, this means we canuse our box in any way we like without
disturbing our neighbours. The retrospective installation was extremely
easy, and took just a few hours fromstart to finish.”Moritz Furrer, Marcello Lopez & Eric
Diaw – Owners, Reebok CrossFit Zürich
