<p><strong>&nbsp; PART 3 - EXECUTION</strong></p>
<p>&nbsp;3.1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PREPARATION</p>
<p>A.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Ensure
that subsoil is approved by Architect or Geotechnical Engineer.</p>
<p>1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Level and compact base material.</p>
<p>&nbsp;3.2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; INSTALLATION</p>
<p>A.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Install
vapor retarder in accordance ASTM E1643.</p>
<p>1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Unroll vapor retarder 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.</p>
<p>2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Extend vapor retarder 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, waterstops, or any other site condition requiring
early termination of the vapor barrier. At the point of termination, seal vapor
retarder to the foundation wall, grade beam or slab itself.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [Specifier
note: The perimeter seal can be handled several ways.&nbsp; When sealing to the slab, </p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; Crete Claw is the best option.&nbsp; When sealing to a stem wall or wall, </p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; the best option is to use StegoTack Tape or
both StegoTack Tape and Stego Term Bar.]</p>
<p>a.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Seal vapor retarder to the entire slab
perimeter using Stego Crete Claw, per manufacturer's instructions.</p>
<p>b.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Seal vapor retarder to the entire
perimeter wall or footing/grade beam with double sided StegoTack Tape, or both
Stego Term Bar and StegoTack Tape, per manufacturer's instructions.&nbsp; Ensure the concrete is clean and dry prior to
adhering tape.</p>
<p>3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Overlap joints 6 inches and seal with
manufacturer's seam tape.</p>
<p>4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Apply seam tape/Crete Claw to a clean
and dry vapor retarder.</p>
<p>5.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Seal all penetrations (including
pipes) per manufacturer's instructions.</p>
<p>6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For interior forming applications,
avoid the use of non-permanent stakes driven through vapor barrier.&nbsp; 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 retarder.</p>
<p>7.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If non-permanent stakes must be
driven through vapor retarder, repair as recommended by vapor retarder
<p>8.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Use reinforcing bar supports with
base sections that eliminate or minimize the potential for puncture of the
vapor retarder.</p>
<p>9.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Repair damaged areas with vapor
retarder material of similar (or better) permeance, puncture and tensile. </p>
<p>10.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For vapor barrier-safe concrete screeding
applications, install Beast Screed (vapor barrier-safe screed system) per
manufacturer's instructions prior to placing concrete.</p>
