When installing new machinery or expanding a manufacturing facility, vibration from heavy equipment can affect nearby machines, processes and building structures.
Bilz offers vibration-isolated foundation solutions designed to reduce vibration transmission and improve machine stability.
How Isolated Foundations Work

Instead of isolating only the machine, the equipment is mounted on a large concrete foundation block that is itself vibration-isolated.
This indirect isolation method helps improve rigidity, stability and dynamic behaviour, particularly for large machines and applications with changing loads.
Bilz can support projects with:
- On-site vibration analysis
- Foundation design and simulation
- Construction supervision
- Isolation system installation
- Final commissioning

Benefits of Isolated Foundations
A properly designed isolated foundation can help provide:
- Reduced vibration transmission
- Improved machine stability
- Lower vibration amplitudes
- Better equipment performance
- Reduced stress on machine components
- Improved stability for robots and material-handling systems
Isolation Pad Foundation Systems
Bilz isolation pads can be installed in multiple layers beneath a concrete foundation block.
Depending on the configuration, natural frequencies below approximately 10 Hz can be achieved.
This is a practical solution for many industrial machine foundation applications.
FAEBI® Rubber Air Spring Foundations
FAEBI® air springs can be used beneath precast concrete foundation blocks.
They are commonly used for machinery such as punching presses and can help reduce vibration transmitted into surrounding areas.
Depending on the system design, natural frequencies around 5 Hz can be achieved.
BiAir® Low-Frequency Foundation Isolation
BiAir® membrane air springs are designed for very low-frequency vibration isolation, typically around 1–2 Hz.
With automatic level control, the system can maintain foundation height even when operating loads change.
Typical applications include:
- Ultra-low-vibration laboratories
- High-end metrology
- Sensitive testing equipment
- Precision manufacturing
Complete Foundation Isolation Solutions
Bilz provides isolated foundation solutions ranging from isolation pad systems to FAEBI® and BiAir® air spring systems.
The most suitable option depends on machine weight, vibration levels, required natural frequency and operating conditions.
