One of the most common misconceptions about floor vibration control is that, to fix the problem, you need to reinforce or treat the entire floor. Not so with CALMFLOOR.

With a highly targeted, active floor vibration control strategy, you only need to address critical vibration pain points – not the entire floor area.

Targeted floor vibration control, not inefficient blanket coverage

CALMFLOOR active mass damper (AMD) units deliver targeted multi-frequency vibration control at key vibration hotspots – the areas that need it most. Using advanced floor vibration simulation, CALMFLOOR identifies exactly where performance dips and resonance risks arise.

The ultra-compact 67kg (148lbs) CALMFLOOR AMD units are then positioned at those critical control points – neutralising floor vibration at the source, without structural changes or disruption.

Pinpointing floor vibration hotspots with CALMFLOOR’s specialist simulation service

Every CALMFLOOR project starts with simulation – not guesswork. Our specialist simulation service and floor vibration expertise will analyse and evidence how your floor actually behaves under real conditions, assessing:

  • Floor slab modal properties
  • Grid span, joist and beam layout
  • Construction materials (e.g. steel deck, mass timber, concrete)
  • Natural frequency and mode shapes
  • Causes of vibration (footfall, equipment, traffic)

This data-led approach allows CALMFLOOR to calculate the precise number of AMDs required and pinpoint exactly where they should go for maximum impact.

This is sustainable, discreet active floor vibration control delivered directly to the source.

Once in place, CALMFLOOR AMDs operate in real time with no audible disruption. They self-regulate in real time using embedded sensors and smart feedback loops, meaning no on-site manual tuning and minimal maintenance.

Single-frequency, floor-wide vibration damping wastes time, cost and carbon

TMDs are frequency-specific, tuned to mitigate a single vibration mode. This means multiple dampers are often needed to tackle even moderate floor challenges. In contrast, CALMFLOOR AMDs respond dynamically across a range of frequencies in real time, delivering more effective control with fewer units.

Added mass, another traditional damping method, requires adding concrete, steel, or mass timber to a structure. This often overcompensates, applying damping everywhere, regardless of where the real issue lies. Added mass damping is inefficient, structurally restrictive, carbon-intensive and expensive.

CALMFLOOR eliminates inefficiency by focusing precisely on the areas that matter.

Compact, low-carbon and targeted, CALMFLOOR AMDs reduce floor vibration by up to 90%. No need for structural over-engineering or added mass, CALMFLOOR optimises structural design potential while supporting Net Zero sustainable building goals from the outset.

How much area does one CALMFLOOR AMD unit control?

That depends entirely on your structure.

On typical floorplates, CALMFLOOR AMDs are spaced across grids ranging from 7.5 m × 7.5 m up to 16 m × 9 m. What matters most isn’t the area itself – but the resonant behaviour of that floor. Every floor performs differently, that’s why we simulate before we install.

Through our simulation service, each floor layout is matched with the most efficient number of AMDs to deliver targeted performance. Once installed, CALMFLOOR AMDs respond dynamically based on how your floor behaves.

Strategic data-led AMD placement delivers vibration control where it matters most

By honing in on floor vibration hotspots CALMFLOOR achieves full-floor, multi-frequency vibration control without blanketing the entire slab. Compared with traditional damping methods, CALMFLOOR’s targeted approach delivers floor vibration control with:

Dynamic multi-frequency floor vibration allows each AMD to deliver targeted vibration floor control exactly where it’s needed, eliminating the need for added steel, concrete or single-frequency passive devices. The result: reduced waste, lower embodied carbon and compliance with sustainability frameworks like BREEAM, LEED and Net Zero.

Mitigate floor vibration today without overengineering

Control what matters, not the whole floor.

You don’t need to reinforce or treat every slab to achieve high-performance floor vibration control. CALMFLOOR pinpoints exactly where damping is needed, delivering full-floor, multi-frequency vibration control by targeting the hotspots, not overengineering the rest.

Whether you’re converting offices into labs, designing long-span environments, or retrofitting live buildings, CALMFLOOR vibration control adapts to your structure – not the other way around. Our simulation-led process ensures every unit works harder, every decision is data-backed and every gram of material serves a purpose.
