Strip-mounted polyurethane quality spring system

Damping soundproofing mat

● Closed-cell polyurethane
● Point support, line support, surface support
● Low water absorption
● Surface static stiffness up to 12 N/mm²
● Extremely high dynamic efficiency
● Excellent mechanical properties
● Outstand

Main features and advantages
The VIAB mass-spring system can effectively reduce the vibrations and noise caused by railway sections. It can be used wherever it is necessary to isolate disruptive vibrations.

VIAB offers three types of mass-spring support structures: plate, strip, or point. The specific type is mainly chosen based on economic and technical considerations. The effect is obvious. In numerous completed short- and long-distance traffic mass-spring systems, the lowest natural frequency can reach 5 Hz.

So far, VIAB’s supported mass-spring systems have been widely used worldwide, covering more than forty cities as well as numerous high-speed traffic sections and entire railway lines.

Advantages
● Effectively isolates vibrations and prevents structural noise
● Selects the most suitable materials for the project to optimize costs
● Easy to install
● Improves the quality of living and working for residents

Application scenarios:

  • Seismic Isolation for Public Buildings
