4Course Objectives After completing this course the participants will have a better understanding of thefollowing:Waterproofing Solutions that Protect the Owner’s Investment By…Improving Indoor Air QualityProtecting Your Concrete Floors And WallsPreserving Structural IntegrityState the Learning Objectives for this presentation. See slide. Note that this educational program is designed to be an interactive program and as such we want to encourage audience participation. We will pose a series of questions throughout this presentation to encourage interaction. Suggestion: Use a flip chart to record architect responses to questions. Write one question on each sheet and record answers below.
5“Do You Know Why Most Vapor Barriers Fail?” Ask the participants “Do You Know Why Most Vapor Barriers Fail?”The solutions available now extend beyond vapor barriers. Since vapor barriers have been the status quo for so long it is good to review common issues with them.
6"85% of Vapor Barriers Fail" Vapor barriers are a well known problem area in the design and construction field.The problem comes from damage during construction.There is significant disagreement on what materials to use, where to place vapor barriers, and how to specify construction methods to avoid damage.What do we mean ?Did you know a vapor barrier on a commercial job may be as thin as the layer of poly placed under a house?Vapor barriers are a well known problem area in the design and construction field.The problem comes from damage during construction.There is significant disagreement on what materials to use, where to place vapor barriers, and how to specify construction methods to avoid damage.
7Where does the "85 %” failure rate come from? The specific quote is taken from a consultant's report to the city of Los Angeles Department of Building and Safety:"…With respect to HDPE (vapor barriers), please be aware that under normal field applications it has been observed to experience a high failure rate reported to be as high as 85% in some cases."The full report, along with a listing of nine large projects known to be leaking and a Los Angeles Times article, can be found at this weblink:Read slideFailure is very common but often is not recorded because the damaged membrane is covered up so quickly.
9Need More Proof ? ASTM E 1643 - 98 SPECIFICATION: Standard Practice for Installation of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete SlabsFROM THE EXCERPTS ABOVE, IT LOOKS LIKE:1. Everybody on the ASTM committee agrees that these vapor barrier materials are likely to fail.2. The committee does not agree on a solution.Read slideThe reason they have a tough time agreeing on a solution is because until now there hasn’t been other good options.
10The following slides include: I. A definition of vapor barriersII. A discussion of current vapor barrier standardsIII. A series of construction photographs which demonstrate the potential for construction abuse and damage to vapor barriersIV. Extracts from materials standards, construction specifications, and engineering bulletins:ASTMPortland Cement Association (PCA)American Concrete Institute (ACI)Read slide
12DEFINITION OF VAPOR BARRIERS The industry uses various terms for vapor barriers:Vapor RetardersVapor BarriersHDPEPolyethylene FilmReinforced polyethylene filmsMembranes, etc.Most of the industry considers the terms to be interchangeable.This presentation will use the term "Vapor Barrier"Read slideAnother common phrase is simply a piece of plastic laid on the ground.
13Vapor Barriers are virtually impermeable polyethylene films which, according to ASTM E 1643"...provide a method of limiting water vapor transmission upward through concrete slabs on grade…”Read slide
15Damage to flooring above the slab by moisture Historically, few construction projects used vapor barriers. However, use has increased in recent years because of concerns about:Damage to flooring above the slab by moistureConcerns about toxic moldIntrusion of chemical vapors and other hazardous contaminants from undergroundRead slideRemember concerns now of moisture causing tile floors to come loose. Also causing gym floor problems. Also with the current mold issue the indoor air quality is coming into play. Some areas are having tough problems dealing with methyns and other types of gas.
16PROPERTIES FOR COMMERCIAL GRADE VAPOR BARRIERS In other words the puncture resistance rating for vapor barriers by ASTME 154 & ASTM1745 is so low there is little chance for protection of a abuse by foot traffic or puncture by almost anything on the slab grade.Discuss Slide chartNote: Puncture resistance requirements are expressed in GRAMS, instead of pounds. (2200 grams = 4.85 pounds, 475 grams = 1.05 pounds)
17Notice how thin this vapor barrier is There are some films that are suitable for some jobs. Obviously moisture, gases, and interior air quality would need to be of minimum concern.Notice how thin this vapor barrier isSource: Portland Cement Association (#V2/144_5)
18Read slideThe next slides should help us be reminded of what we are asking simple vapor barriers to protect against regular slab on grade construction. You should move through slides without a lot of discussion as these are self explanatory. This is where you show but don’t talk much and make up good time to go on through the presentation.On most large projects, steel reinforcement (REBAR) is installed over the vapor barrier.The purpose of rebar is to minimize future cracking of the concrete slab, and to reduce warping or curling.Source: (#a00305)
19Read slideRebar installation includes cutting, which creates both sparks and sharp edges.Source: (#204602)
20Rebar must be fastened at intersections to keep it evenly spaced. Read slideRebar must be fastened at intersections to keep it evenly spaced.In this photo, the rebar is being welded together. If this job had used a vapor barrier, holes could have been burnt.Source:
21Read slideAfter rebar installation is complete, there are usually many areas where sharp edges touch the vapor barrier.Source: (#a00306-section zoom)
22There is also a lot of foot traffic on jobsites, as well as equipment. Read slideThere is also a lot of foot traffic on jobsites, as well as equipment.Source: Portland Cement Association (#82_5a)

26Vibration of the concrete is a widely used method of consolidation. One manufacturer, Vibco, offers vibrators with head diameters between 1-3/8” and 3”.Read slideAnd describe chartSources: Wycotool (Vibrator Drawing) Vibco (Vibrator Specifications)
27"Avoid use of stakes driven through vapor retarder" If you haven't seen enough unintentional construction damage, we should mention intentional vapor barrier damage:ASTM E , section 6.3:"Avoid use of stakes driven through vapor retarder"PCA Engineering Bulletin 075, page 15:"The practice of intentionally punching holes through a vapor retarder to allow bleed-water to exit the slab bottom is unacceptable because it defeats the purpose of the membrane."Read slideEvery job has people driving stales through the vapor barrier. The concrete association says it’s not good to allow the vapor barrier to bleed. Yet, there is often major disagreement between engineers concerning this.
28Summary of the problem: Increased concerns about vapor penetrating slabsA. Moisture damages flooringB. Toxic mold from moisture vaporC. Chemical vapor intrusionD. Lawsuit potentialThe industry standard is Vapor Barriers made of polyethylene:A. ThinB. Industry standard for puncture resistance: so low that it is expressed in GRAMSASTM E 1643 states that polyethylene vapor barrier materials are highly vulnerable to construction damage.The big problem is construction damage.Walk through this slide. This is important to those that have slept on you so far in the presentation. Wake ‘em up again right here before you go further.
29THE INDOOR AIR QUALITY PROBLEM Now we’ll show you new technology that corrects a lot of the problems we have seen.Under-Slab Membrane
30The Next Generation of Under-sealing Waterproofing Membranes Presenter: Remember the beauty of this presentation is that the “ Underseal” products are named generically. So as you talk about each one you are actually getting to say the product names. Remember, not to call these Polyguard products, but refer to them as solutions.Read Slide
31Problems: Sick Office Solutions: Happy Office These Products Act As Barriers To:Moisture/WaterMethane GasRadon GasToxic ContaminantsTermitesPesticidesStress CracksThe solution is a protection package.Read slideBelow grade self-sealing membrane system with a level of protection never before available.
32THE UNDER-SLAB MEMBRANE ACTS AS A BARRIER TO WATER & MOISTURE PolyethyleneRubberized AsphaltGeo-textile Fabric- Under Slab Membrane ( Hand out physical sample ). Break down the product by layer and thickness.1. The poly is tough. It is also white in color which helps ease the application during the hot months.2. The asphalt gives self-healing properties for puncture wounds and waterproofing mentality.3. The fabric has been used in highway applications for years and is extremely tough and durable.4. The concrete penetrates the fabric to create a 28 lb. psi pull adhesion. With compression by the weight of concrete, when the concrete cures the asphalt also gains adhesion directly to the slab.5. The material is totally cured so there are no concerns about spraying chemicals in the air.6. Typically this is used horizontally , but may also be used vertically for a stiffer wall support for uneven lagging or for shot-crete applications to help eliminate rebounding.7. Also helps reduce cracking in the slab.8. Remember you’re getting waterproofing and not just a vapor barrier.9. A built in lap system on the side of the sheet reduces expensive labor and costly side lap tapes.Reduces the amount and severity of cracking-more facts

37THE BLIND SIDE MEMBRANE ACTS AS A BARRIER TO WATER & MOISTURE PolyethyleneRubberized AsphaltGeo-textile Fabric– Blind Side Membrane is the little brother to underslab membrane. Typically for vertical negative side waterproofing. Walls need to be basically smooth. If not then it may be necessary to use the underslab material.Break down the product by layer and mills.2. Remind audience this is typically applied after the drain board and gains extra support by this. Therefore, this eliminates the need for a heavier piece and explains why you only have a four mill poly instead of a twenty mill poly as the underslab membrane does.3. Obviously this also helps reduce unnecessary cost.4. Built in lap system reduces labor and costly taping of side laps.

42THE SPLIT SLAB MEMBRANE ACTS AS A BARRIER TO WATER & MOISTURE 20 mil. PolyethyleneRubberized AsphaltProduct Detail 1 - Split Slab MembraneThis is used between two layers of concrete. Often seen in parking garages.Break down the layers and mills.The twenty mill of poly gives an extra toughness to help keep the membrane from getting torn up before it is covered with protection board and or drain board. May projects with typical 60 mill membranes get damaged. This extra protection also may help to reduce how thick a protection board is used to balance cost issues. The sheet is a white poly, which helps the ease of application in summer for handling.

46THE PROTECTED WALL MEMBRANE ACTS AS A BARRIER TO WATER & MOISTURE 20 mil. PolyethyleneRubberized Asphalt- PROTECTED WALL MembraneGo over layers and mills.This sheet has an advantage: it may be used in place of typical 60 mill sheet and a separate protection board.The puncture resistance is far superior to 1/4” fan-fold protection board.Eliminates the need for a worker to have to stand and hold protection board in place while the back-filling is going on.Puts 20 mills on the exterior and the sheet won’t get torn up so easily by working crews before the backfill gets done.Eliminates another step of labor putting up protection board and the problem of trying to keep the board in place.Costs are similar between this new solution and the old method.
49ANTI-FRACTURE MEMBRANES Anti-fracture membranes protect ceramic tile by providing a stress absorbing layer between the substrate and the tile. If the concrete substrate underneath cracks, the stress of the crack is not transferred up to the brittle ceramic tile. The stress is absorbed by the rubbery nature of the rubberized asphalt.Read SlideThis and the next two slides help show the mentality of the toughness and stress reduction in the new technology of solutions for under the slab and blind-side applications.
