Construction and industry



Calenberg elastomeric bearings and their isolating properties have proven their worth wherever people and structures need to be protected against tremors or where there is a need to reduce vibrations from technical equipment and machines.

Vibration isolation in buildings

Housing and infrastructure are constantly being built closer to one another more frequently due to expanding urbanisation.
This means buildings are increasingly exposed to mechanical vibrations from adjacent roads, railway lines and industrial plants.
These vibrations continue inside buildings, where they are perceived as tremors and secondary air-borne sound by occupants and
are detrimental to the quality of living and work environments.

Calenberg offers different solutions (passive isolation) to overcome precisely this problem
and reduce vibration and secondary air-borne sound effectively.

Calenberg’s dynamic bearings can be used to provide solutions such as the following:
  • Horizontal and vertical decoupling of structural elements in contact with soil (base plates, underground walls)
  • Decoupling of above-ground structural elements
  • Decoupling on structures such as pile heads (highly resilient bearings)
  • Slurry walls between the building and source of emission

Vibration isolation for machines

Impacts cause unwanted vibrations and excitations from machines, ventilation and air conditioning units
and other engineering systems when they are in operation.
The energy this generates is transferred into building structures and produces noticeable tremors
and secondary air-borne sound. This impairs living and work environment quality in adjacent spaces.

Calenberg offers customised bearings for machine vibration isolation (source isolation).
Another area of use is isolation for highly sensitive installed systems against tremors and vibrations in surrounding areas (passive isolation).

Calenberg also offers tailor-made solutions for such applications.

Calenberg’s dynamic bearings can be used to provide solutions such as the following:
  • Direct decoupling of machines (bearing directly under the machine without a machine base)
  • Decoupling of machine bases (bearing directly under the machine base)

Full-surface decoupling

Point-shaped decoupling

Ceiling decoupling
Strip-shaped decoupling

Side wall decoupling

Slot wall

Direct decoupling of machines

Decoupling of machine foundations


Calenberg solution for acoustic isolation
The objective of sound insulation of buildings is to create a pleasant living and working environment by providing optimum insulation against structure-borne or airborne sound as well as impact sound. Structural soundproofing is designed to avoid disturbances caused by noise from other rooms and stairs, from building services installations and external noise.

There are many different noise sources and transmission paths in buildings, e.g. apartment partition walls, staircase walls, apartment ceilings or exterior building elements, so that various measures must be taken to reduce noise. Calenberg provides effective sound insulation measures and thus ensures a long-lasting noise reduction.
