        PART 3 - EXECUTION

       3.1        PREPARATION

      A.          Ensurethat subsoil is approved by Architect or Geotechnical Engineer.

      1.           Level and compact base material.

       3.2        INSTALLATION

      A.          Installvapor barrier in accordance ASTM E1643.

      1.           Unroll vapor retarder with the longestdimension parallel with the direction of the concrete placement and face lapsaway from the expected direction of the placement whenever possible.

      2.           Extend vapor retarder to the perimeterof 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 byimpediments, such as dowels, waterstops, or any other site condition requiringearly termination of the vapor barrier. At the point of termination, seal vaporretarder to the foundation wall, grade beam or slab itself.            

                    [Specifiernote: The perimeter seal can be handled several ways.  When sealing to the slab,

                    Crete Claw is the best option.  When sealing to a stem wall or wall,

                    the best option is to use StegoTack Tape orboth StegoTack Tape and Stego Term Bar.]

      a.           Seal vapor retarder to the entire slabperimeter using Stego Crete Claw, per manufacturer's instructions.

      OR

      b.           Seal vapor retarder to the entireperimeter wall or footing/grade beam with double sided StegoTack Tape, or bothStego Term Bar and StegoTack Tape, per manufacturer's instructions.  Ensure the concrete is clean and dry prior toadhering tape.

      3.           Overlap joints 6 inches and seal withmanufacturer's seam tape.

      4.           Apply seam tape/Crete Claw to a cleanand dry vapor retarder.

      5.           Seal all penetrations (includingpipes) 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'speel-and-stick adhesive base is fully adhered to the vapor retarder.

      7.           If non-permanent stakes must bedriven through vapor retarder, repair as recommended by vapor retardermanufacturer.

      8.           Use reinforcing bar supports withbase sections that eliminate or minimize the potential for puncture of thevapor retarder.

      9.           Repair damaged areas with vaporretarder material of similar (or better) permeance, puncture and tensile.

      10.        For vapor barrier-safe concrete screedingapplications, install Beast Screed (vapor barrier-safe screed system) permanufacturer's instructions prior to placing concrete.
