Installation Overview

  • RESILIENT INTERFACE

    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.

  • BOND BREAKER

    Cover entire floor with bond breaker (Poly Sheeting by KNC).  This ensures that the isolated slab can be lifted into place.

  • POSITION MOUNTS

    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.

  • CONCRETE REINFORCEMENT

    Install concrete reinforcement per project drawing and design specifications.

  • POUR CONCRETE

    Pour concrete and allow to cure.

  • DRIVE LIFTING SCREWS

    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.



Design Guidelines


FAQ


  • “What information is included in your shop drawings?”

    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.

  • “What information is needed for Kinetics to create shop drawings?”

    The timely gathering of essential information makes difference in our turnaround time. A guide for helpful information can be found here.

  • “Should isolated floor drawings be in the Structural or Architectural plans?”

    As isolated slabs are by their nature non-structural, they typically reside in the Architectural Plans.

  • “What structural concerns are there?”

    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.

  • “Who should design the rebar spacing in the isolated slab?”

    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.

Structural Floor Flatness

  • FF = 38 (SOV)
  • FF = 25 (MLV)
  • Kinetics requires a specified overall value of Floor Flatness FF = 38 and a minimum local value of Floor Flatness FF = 25. This means that locally the floor is considered “Flat” and globally the floor is considered “Good” (“Flat” and “Good” are terms defined by ACI- American Concrete Institute Guidelines Section 302). Conventionally this means locally a 10 foot straight edge would have 1/4 inch of variation, and globally the variation would be less than 3/16 inch.
  • These requirements are necessary for Kinetics spring lift slabs because the top of the structural floor becomes a pouring form for the bottom of the isolated slab. As the canisters are a fixed height, inconsistencies in the structural floor become reflected in the isolated slab. If the structural floor is not considerably flat then issues can arise that adversely affects the acoustical, and even possibly the structural performance of the isolated, elevated slab. The standard deviation of varying thickness of the slab could be significantly more than was accounted for in the selection of the isolators; this could lead to under or over isolation, incorrect leveling screw set dimensions, and structural stress in the isolated slab. This can also make lifting the slab to a constant elevation very difficult.
  • Normally FL is typically specified with along with these numbers for levelness. While flatness between mounts is critical, the slope of a floor is not nearly as crucial. Please contact Kinetics if a sloped floor is being considered with spring isolated slabs.

    • Load path and load (in pounds or KIPS) of any stationary equipment, millwork, etc.
    • Load path and weights of any operable partitions/curtains, seating, equipment, etc.
    • Identify and provide equipment and materials with their respective weights that may be moved on floor during or after construction.
  • Structural:
    • Framing plan and/or edge-of slab plan
    • Restrictions/requirements of isolator spacing, if any (typically 48" on center each way)
    • Type of concrete (normal weight, lightweight, etc.)
  • Acoustical:From Acoustical Consultant, if applicable
    • Venting Details

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.
