Lift Slab Floor Mount
Lifted isolation mounts decouple concrete slabs from non-isolated structural floors.

Adhere resilient interface (PPI by KNC) to all penetrations and perimeters. PPI prevents sound vibration from transferring from the isolated slab to the non-isolated structure.
Cover entire floor with bond breaker (Poly Sheeting by KNC). This ensures that the isolated slab can be lifted into place.
Place Castings with Isolators with per engineered shop drawings (by KNC or KNC Representative). Caulk or tape to bond breaker, preventing concrete from leaking beneath Mount.
Install concrete reinforcement per project drawing and design specifications.
Pour concrete and allow to cure.
Drive Leveling Screws two or three turns for each Mount in sequence until floor is raised. Trim perimeter bond breaker and remove PPI tear strip. Apply sealant in gap.
Our shop drawings include coordination of the live and dead loads, a dimensioned isolator layout including extra isolators for heavy loads, as well as project specific and general installation guidelines for the contractors.
The timely gathering of essential information makes difference in our turnaround time. A guide for helpful information can be found here.
As isolated slabs are by their nature non-structural, they typically reside in the Architectural Plans.
Ensure that the structural slab has the proper depression to include the isolated slab as well as the airspace created after the slab is lifted. Structural slab stiffness and capacity considerations must be made relative to the activity of the floor (e.g. if the floor activity is to include the drop of heavy, a stiffer structural slab is required). The existing floor should be flat as the isolators can only mirror the floor on which they are resting. If there are seismic concerns, designing a curb capable of restraining the isolated slab will eliminate the cost of using in-slab restraints.
If your project isn’t employing a structural engineer of record, then slab design should go to an independent third party firm to avoid any potential conflict-of-interest with isolator layout. Kinetics maintains relationships with independent structural engineering firms experienced in isolated slab design who can seal the reinforcement design in all fifty states.
The FLM system offers flexibility when the construction sequence demands movement of exceedingly heavy loads across a yet-to-be “jacked-up” slab. Otherwise, consider RIM or FIC which allow for faster construction by eliminating FLM’s lift sequence.
