Instant vibration control for Japan’s high-performance buildings
箱から出してすぐに設置できる、世界唯一の床振動制御ソリューション
GERB Japan
CALMFLOOR
CALMFLOOR’s revolutionary AMD technology is proven to reduce vertical floor vibration by up to 90% to lab-level sensitivity standards. CALMFLOOR transforms floor vibration performance, enhances the building’s asset value and considerably reduces embodied carbon. Low cost, low carbon, and virtually maintenance free by design, CALMFLOOR is the floor vibration solution for the critical challenges of modern buildings, including how to lighten floor weight while improving vibration performance.
CALMFLOOR AMDs are ultra-compact, lightweight (just 67kg) and designed to deliver active floor vibration reduction directly, and only, to the areas that need it. Units can be installed in under a day to deliver high-performance, vibration-controlled environments instantly. No disruption, no delays, no downtime.

CALMFLOOR AMD technology can be experienced first-hand through local demos delivered by the GERB Japan team. Arrange a demo today and see how instant vibration control can transform your building.
BOOK A DEMO
Case study: F1 Arcade gaming experience centre, Boston, USA
When 62 F1 driver simulators generated excessive vibration in a tall building in Boston, USA, peak-time restrictions were imposed. Our challenge was to remove these restrictions and resolve the problem fast.
Our UK Technical team flew to the USA within days, conducting tests, structural dynamic FE modelling and simulations that proved CALMFLOOR would bring vibrations to within acceptable levels – without structural intervention, downtime or disruption to operations. 11 AMDs were installed in strategic locations on the floor, reducing vibration instantly by 76% and restoring comfort and calm to neighbouring occupants. All this within just six weeks.

Case study: Multi-use commercial building, London, UK
An existing composite steel-concrete office floor set within a multi-use commercial building in London, UK, was experiencing human-induced vibration problems. With conventional structural solutions unviable due to ongoing works, we knew we could significantly reduce vibrations and upgrade floor performance.
AMD units were deployed to significantly reduce excessive floor vibrations and achieved a vibration reduction of almost 75%. The building’s long floor span design, versatility and comfort remained intact and the environment was instantly upgraded to a high-performance, high-quality, feel-good space with successfully controlled vibrations.

CALMFLOOR technology explained
CALMFLOOR AMDs use an inertial mass driven by an electric motor to deliver active vibration control by simultaneously sensing and reducing structural motion continuously. This generates the requisite control force to deliver unprecedented damping force – precisely to the identified hotspots on the floor that need it. Key to it all is CALMFLOOR’s unique ability to control several vibration frequencies simultaneously.
Technical specifications
Typical frequency range: 3-30Hz
Dimensions: 630 x 385 x 122mm
Power: 100-240V, 50/60Hz AC single phase 5A supply required
Network connection: Cat 5e/6 Ethernet
Weight: 67kg total, internal moving mass 35kg
Mounting options
CALMFLOOR units can be mounted in the ceiling void to control the floor plate above, placed directly on the surface of the floor plate to be controlled or attached to the web of the beam supporting the floor. Every mounting method delivers the same standard of floor vibration control.
