NOISE CONTROL BUILDING MATERIALS

INSTALLATION OVERVIEW

DOWNLOAD
  • 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 CANISTERS

    Place Canisters with Wooden Lid per engineered shop drawings (by KNC or KNC Representative).  Caulk or tape to bond breaker, preventing concrete from leaking beneath Canister.

  • CONCRETE REINFORCEMENT

    Install concrete reinforcement per project drawing and design specifications.

  • POUR CONCRETE

    Pour concrete and allow to cure.  Remove and discard wooden lid and screws.

  • ASSEMBLE ISOLATORS

    Grease Lifting and Leveling Screws.  Place Spring Assembly into cavity per engineered shop drawings.  Balance Steel Lid on Leveling Screw, insert and engage (do not tighten) Lifting Screws. 

  • DRIVE LIFTING SCREWS

    Drive Lifting Screws two or three turns for each isolator in sequence until floor is raised.   Trim perimeter bond breaker and remove PPI tear strip.  Apply sealant in gap.
