FSN Jack Up Floating Floor Isolation Mounts

We believe that the most fool-proof and safest way to establish the air gap is the jack-up or lift-slab method. The FSN system ensures there is no bridging of the two elements due to slurry ingress.
Plastic sheeting is placed on the sub-floor as a breaker layer, isolators are placed on the plastic sheeting, reinforcing steel or mesh rests on the isolator housings and the concrete floor is poured. After the concrete has cured, the slab is lifted to elevation by turning adjustment bolts above each isolator to any specified air gap between 25mm -100mm.

The Mason FSN Jack Up floor system does not need to be jacked into position immediately. It can be left sitting on the structural slab enabling upper floor props to be installed and formwork cycle to continue for floors above.

All of the Mason FSN Jack Up Floor rubber mounts have a 3X overload built in to enable heavy equipment to be rolled over the slab into position.

FS Jack Up Floating Floor Isolation Mounts

Situations arise where there is a requirement for a lower natural frequency in the floating floor elements that what can be achieved by a rubber isolator.
We have engineered purpose build jack up isolators which house springs. The springs are installed once the concrete is poured. The slab is jacked into position in the same manner our our FSN type jack up isolators.
Plastic sheeting is placed on the sub-floor as a breaker layer, isolators are placed on the plastic sheeting, reinforcing steel or mesh rests on the isolator housings and the concrete floor is poured. After the concrete has cured, the slab is lifted to elevation by turning adjustment bolts above each isolator to any specified air gap between 25mm -100mm.
