Lift slab floating floor systems that incorporate spring isolator assemblies to decouple four inch thick concrete slabs from non-isolated structural floors are used where vibration and impact are critical and of greater concern than airborne noise transmission.

LiftWrx - 4" Thick Slab Spring Lift Mount

Proven effective for intense impact applications ranging from floors for sensitive lab measuring equipment (e.g. metrology and surgical labs) to sports floors over retail/commercial spaces.

Spring isolators natural frequencies (fn) of 3.13 Hz for 1″ rated deflection springs and 2.21 Hz for 2″ rated deflection spring. Other rated deflection springs are available.

Factory-engineered shop drawings detail consider spacing, spring load/deflections and structural floor flatness requirements.

Rubber cap assembly protects against resonant frequencies.

In-slab or perimeter seismic restraint elements available where required.

Springs ship in ready-to-install sub-assemblies.

Castings are stocked ready to ship.
