Reliable protection against vibration and noise

Effective isolation to protect buildings against vibration and noise is crucial in urban environments where high-quality building plots are becoming increasingly scarce. The construction of buildings on dynamically loaded land requires intelligent solutions. The main sources of mechanical vibrations are often transport routes in the vicinity, especially underground railway lines such as subway or rapid transit sections that lead to disruptive noise and noticeable vibrations in surrounding structures.

This presents planners, investors and developers with major challenges when it comes to targeted solutions for effective soundproofing and minimising vibrations that occur. This is where innovative solutions for dynamic decoupling and acoustic separation are required: not a patchwork of individual measures, but rather well thought-out concepts for effective building base isolation.

Our customised sound control solutions are individually adapted to specific requirements. The materials Sylomer® and Sylodyn®, developed specifically for sustainable vibration control in buildings, are durable, maintenance-free and are evidenced by numerous successful reference projects around the world. The elastic bearing protects the building structure and the residents in equal measure, increasing the quality of life and working environment and in turn the value of the property.

Advantages of building base isolation with Getzner

Effective protection against vibration and noise: Our solutions provide effective protection against vibration and noise, in particular for buildings in the vicinity of very busy transport routes such as railway lines and roads.
Increased value and improved health for residents: The base isolation of buildings on Sylomer® or Sylodyn® ensures effective shielding against vibration and noise. This creates a quieter and more pleasant environment in the building and can increase the residents’ quality of life over the long term.
Bespoke protection for building foundations: Our applications can be tailored to the situation, protecting the building structure and minimising secondary airborne noise
Expert service: Our experienced team is available to provide comprehensive advice and answer any questions on vibration protection and vibration isolation. We work closely with planners and engineers during the design phase to develop custom solutions.

The complexity of vibration and oscillation control for buildings

The base isolation of buildings is a reliable method for permanently minimising vibration and oscillations, and improving the quality of life for residents.

The effective vibration shielding and soundproofing ensure that there is no impact from noise and vibrations. This is particularly relevant for railway station complexes and buildings in the vicinity, where railway traffic can generate significant vibrations.

By targeting the causes of vibration and providing effective protection measures, elastic building bearings play a significant role in ensuring the stability of buildings and the wellbeing of their residents. This is a complex challenge that requires a differentiated approach using a range of applications such as full-surface bearings, discrete bearings or bearings alongside walls. Custom design by our team of experts in line with the specific requirements for each building is crucial to make these protection measures as effective as possible.

Materials in the building base isolation

Our materials have all the properties required for the effective elastic shielding of buildings. With a precisely defined degree of elasticity that can retain its dynamic properties for decades, they are maintenance-free and have been tried and tested over the long term.

Sylomer® is a leading material for vibration insulation. It reduces vibrations, noise and maintenance costs in building bearings and increases comfort in rooms subject to vibrations.

Sylodyn® is used for vibration protection in buildings, impact sound insulation and the mounting of machinery. The closed-cell elastomer does not absorb water and offers better dynamic properties than Sylomer®. The material properties can be customized to meet specific requirements.

Relomer® this granulate-based polyurethane elastomer combines resilience and damping characteristics and offers a resource-efficient alternative for many vibration protection applications – and while retaining the advantages of conventionally produced polyurethane.

Our materials provide planners with technical materials for elastic bearings that enable a wide range of different designs.
