    PART 3 – EXECUTION

    3.1 PREPARATION

    A. Ensure that subsoil is approved by Architect or Geotechnical Engineer.
    1. Level and compact base material.

    3.2 INSTALLATION

    A. Install vapor barrier in accordance with ASTM E1643 and manufacturer’s instructions.
    1. Unroll Pango Wrap Termite/Vapor Barrier with the longest dimension parallel with the direction of the concrete placement and face laps away from the expected direction of the placement whenever possible.
    2. Extend Pango Wrap Termite/Vapor Barrier to the perimeter of the slab. If practicable, terminate it at the top of the slab, otherwise (a) at a point acceptable to the structural engineer or (b) where obstructed by impediments, such as dowels, water stops, or any other site condition requiring early termination of the vapor barrier. At the point of termination, seal Pango Wrap Termite/Vapor Barrier to the entire slab perimeter using Pango Claw, per manufacturer's instructions.
    3. Overlap joints a minimum of 6 inches and seal with manufacturer’s seam tape.
    4. Apply Pango Tape and Pango Claw to a clean and dry membrane
    5. Seal all penetrations (including pipes) per manufacturer’s instructions.
    6.           For interior forming applications, avoid the use of non-permanent stakes driven through vapor barrier.  Use blunt-end and/or threaded nail stakes (screed pad posts) and insert them into Beast Foot. Ensure Beast Foot’s peel-and-stick adhesive base is fully adhered to the vapor barrier
    7.           If non-permanent stakes must be driven through vapor retarder, repair as recommended by vapor retarder manufacturer.
    8. Use reinforcing bar supports with base sections that eliminate or minimize the potential for puncture of the vapor barrier.
    9. For vapor barrier-safe concrete screeding applications, install Beast Screed (vapor barrier-safe screed system) per manufacturer’s instructions prior to placing concrete.
    10. Repair damaged areas by cutting patches of Pango Wrap Termite/Vapor Barrier, overlapping damaged area a minimum of 6 inches and taping all sides with Pango Tape.
