  • Inteplast Group, the largest plastics extruder and resin producer in the world is the manufacturer of the Barrier Bac product line. Barrier Bac is a 12 year old product line has been the fastest growing vapor retarder in the United States for the past 4 years. The entire Barrier Bac product line is manufactured in the United States with 100% US resins and labor.
  • My name is Dave Zill. A graduate of the University of Tennessee (Geology), I have spent my career in the geotechnical engineering and construction business.
  • These are the 2 reason you’d typically use a vapor barrier – slab on grade, beneath conditioned space OR slab on grade under moisture sensitive flooring. This is essentially the most important information to take away from this presentation.
  • Table of values used in HUD Research Paper #28. This technical research is one of the most referenced in the industry.
  • Based on the data provided in the previous slide, as a concrete slab dries and cures, nearly 12 gallons of moisture is released by the slab every 24 hours for every 1000 SF of slab.
  • It’s expensive to condition a space. The HVAC system in your project is typically designed to condition the space by removing humidity.
  • The ground water in reference is on-site moisture – by definition, soil is 100% humid. Water vapor travels from areas of high humidity to areas of lower humidity. With a “dehumidifier” running above the slab, the HVAC system “pulls” water vapor from below the slab and into the building, thus forcing itself to run longer and more expensively. A vapor retarder will effectively shut off the water vapor entering from the building site.
  • A typical water-cement ratio would be ~ .50. Here, three scenarios are presented: Bottom in Contact with Water (Concrete is placed directly on wet ground) Bottom exposed to water vapor (concrete placed on bare soil with no visible moisture – but remember soil is, by definition 100% humid) Bottom Sealed – (Concrete place vapor retarder)
  • The latest avenue for pipe bank sealing is the place granular sodium bentonite around the penetrations and simply saturate with a water. It works and it is quicker and easier than tape and mastic.
  • These are the current codes for vapor retarders.
  • There’s really no reason to use anything but a Class A vapor retarder.
  • This chart is from the American Concrete Institute (ACI). Please note, ACI has recently changed it’s stance on Figure 3. Due to the relatively large risk of water (irrigation, rain, etc…) filling the space below the slab and the vapor barrier acting as a bathtub, ACI recommends Figure 3 ONLY when the building site is totally in the dry (shell built) and the slab and granular material are fully encapsulated on all sides.
  • Example of a cross laminted LDPE membrane being installed.
  • Cross laminated membrane installation. Note the number of hazards on this jobsite. Will your vapor retarder survive construction?
  • Again, constructability and proper installation is key.
  • On the slab on grade, notice the vapor retarder has pulled away from the concrete. This is called “pocketing” and is caused by settling of the building pad or granular materials. ACI clearly states the vapor retarder should remain in direct contact with the concrete at all times. Pocketing is common and nearly impossible to prevent, thus peal adhesion (how well does the vapor retarder “stick” to the concrete is critical. Some may say hydrostatic pressure will “push” the vapor barrier upward, but the nonlinear nature of this pressure over a building site would make this virtually impossible.
  • It is important to understand that cross laminated LDPE samples provide, on average, more than 8 lbs of peel adhesion. Remember ACI recommends constant constant contact with the slab – Do you know the peel adhesion of your current vapor retarder?
  • There are many composite vapor retarders on the market as well. Many are used for expansive soils, very high dollar floor ($25 / SF and up), and very heavy slabs.
  • The added strength of the geotextile on this cross laminted LDPE membrane allows for greater constructability, peel adhesion, and a higher coefficient of friction providing for improved safety.
  • This inspector is showing the geotextile on a cross laminated LDPE composite vapor retarder is placed to receive the concrete (black side up in other words).
  • Leed description.
  • Geogrid reinforced Segmental Wall and slope technology can earn credits under Sustainability of sites, energy and atmosphere, materials and resources, and innovation and design, out of the 69 points available.
  • Leed requires submittal of the design concept for points in this category.

    45. 59. Recommendations <ul><li>Under slab vapor retarders are recommended for slabs below conditioned spaces and slabs that are covered with flooring systems. </li></ul><ul><li>Under slab vapor retarders should have a perm rating at least equal to the flooring system’s, inclusive of its adhesive. </li></ul><ul><li>Cushions and blotters of sand, gravel or trimmable fill should not be installed on top of under slab vapor retarders. </li></ul><ul><li>The vapor retarder should have all laps, seams, penetrations and terminations sealed. It should either carry across footings, pile caps, grade beams and foundations or be turned up to the top of the slab at these elements and sealed. </li></ul>
