Calenberg Ingenieure GmbH

About us

Calenberg has been carrying out research into elastomeric materials technology for over 47 years. We operate as a solutions provider for static component bearings, vibration isolation and structure-borne sound control worldwide.

In construction and industry, our aim is to protect construction works against tremors, reduce
vibrations and increase living comfort.

Besides construction and industry, we also focus on railway systems and environmental applications.

Made of synthetic and natural rubber, our railway systems products deliver enhanced elasticity in track bed structures and protect the overall track bed system due to their material characteristics. What‘s more, they also reduce wear in such components.

Special products in our Environment Division allow us to provide optimal noise control with our noise barrier as a flexible sound insulation solution and our OIL-EX absorption mat ensures subsoils are effectively protected from contact with harmful substances.

Calenberg has formed part of the potent LISEGA SE consolidated group of companies since 2017 and makes use of the group’s global structure to advise customers efficiently on a local level and develop and offer customer-specific elastomeric solutions.

OIL-EX absorption mat for effective environmental protection

The OIL-EX absorption mat absorbs liquid hydrocarbons such as oils, low-viscosity lubricants, fuels and organic solvents and selectively binds the hydrocarbons from emulsions. The liquids are distributed over the surface of the mat thanks to the absorption layer’s shape and are subsequently bound in the material matrix. Surface water is not bound and drains off. The absorbed liquids remain in the mat and cannot be squeezed or rinsed out. Characteristics: • Absorption effect regardless of weather and temperature • Short absorption time • Full pedestrian access and restricted vehicular access • Absorbed media cannot be extruded or flushed out • Can be used on unpaved surfaces • Easy handling (installation, cutting to size) • Suitable for mobile use • Shock absorbing effect • Noise and thermal insulation • High proportion of recycled raw material • Long service life
