HIGH PERFORMANCE UNDER-SLAB VAPOR BARRIERS

VAPOR BARRIER WHAT TO LOOK FORASTM E 1745 (Standard Specification for Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs) standardizes vapor barriers/retarders according to various performance properties. The three classes (A = highest, B = middle, C = lowest) are based on a membranes resistance to punctures, tears and water vapor. When choosing under-slab vapor barriers/retarders it is important to look for products that are independently tested and exceed all ASTM E 1745 requirements. Furthermore, vapor barrier/retarder products should be made from virgin (non-recycled) resin to assure long term protection.

VAPOR BARRIER SOLUTIONVIPER VAPORCHECK II (VIPER II) is the first line of defense against all damaging water vapor and soil gas threats existing below the concrete slab. VIPER II is a multi-layer, extruded, virgin polyolefin under-slab vapor barrier/retarder. The virgin resin used to manufacture VIPER II contributes to it’s long term stability and prevents the material from breaking down when buried below the slab. VIPER II is engineered with superior resistance against punctures, tears and water vapor. The high puncture resistance and tensile strength greatly reduce potential damage when exposed to rigorous job site conditions. Furthermore, VIPER II products have very low water vapor permeance properties which are key to preventing water vapor migration.

VAPOR BARRIER BACKGROUNDWater vapor from sub-slab conditions will pass through the pores of an unprotected concrete slab through vapor diffusion. This vapor transmission creates a conflicted environment for the floor coating or adhesive. Because government regulations were established to reduce volatile organic compounds (VOCs) found in numerous architectural coatings, specifically floor coatings and adhesives, many solvent based flooring materials have been changed to water based. When exposed to water and alkalinity these water based coatings and adhesives are prone to re-emulsification resulting in costly flooring failures. In addition to flooring failures, moisture migration also creates poor indoor air quality (IAQ), mold, mildew, fungi and damage to the slab and its components.

VAPOR BARRIER PURPOSEThe infiltration of water vapor and gas from the earth through concrete slabs is a costly building liability. Under-slab vapor barriers/retarders provide an inexpensive insurance policy to protect floors and other moisture sensitive equipment within the building's interior. The definition of a vapor barrier/retarder, according to ASTM E 1745, "is a material or construction that impedes the transmission of water vapor under specified conditions." By inhibiting moisture and soil gas migration, under-slab vapor barriers/retarders greatly reduce condensation, retard mold growth, provide healthy breathing conditions within a building, prevent flooring failures and aid in controlling structural degradation.

3.1 BASIC USEViper II 15-mil is a unique high strength polyolefin based under-slab vapor barrier specifically designed for preventing moisture migration through concrete slabs-on-grade. Viper II 15-mil reduces water vapor emission transfer and moisture migration from entering the building envelope on commercial, industrial and residential applications. Viper II 15-mil controls condensation, mold, mildew, degradation and prevents costly flooring failures and damage to moisture sensitive furnishings within a building’s interior. Viper II 15-mil may be used to reduce radon and methane gas migration and is resistant to other adverse soil conditions.

3.2 COMPOSITION & MATERIALSViper II 15-mil is manufactured using the latest generation of prime virgin (non-recycled) polyolefin resin, constructed in a multi-layer plastic extrusion process and engineered with physical properties that maintain long term performance.

5.3 SEAMS AND PENETRATIONSSeal around pipes, support columns or any other penetration with Viper VaporPatch, VaporCheck Mastic or at a minimum, a combination of Viper II 15-mil and Viper Vapor Tape. Doing so creates a monolithic membrane between the surface of the slab and moisture sources below.Holes or openings through Viper II 15-mil should be effectively sealed with Viper Vapor Tape, Viper VaporPatch or VaporCheck Mastic to maintain the integrity of the vapor barrier. Overlap joints a minimum of six inches. Seal overlap together with Viper Vapor Tape and/or Viper Double Bond Tape.

5.4 PROTECTIONWhen installing reinforcing steel and utilities, in addition to the placement of concrete, take precaution to protect Viper II 15-mil. Carelessness during installation can damage the most puncture-resistant vapor barriers. Provide for additional protection in high traffic areas. Place standard reinforcing bar supports on Viper II 15-mil. The strength characteristics of Viper II 15-mil will help guard against possible punctures caused by reinforcing bar supports.Avoid driving stakes through Viper II 15-mil. If this cannot be avoided, each individual hole must be repaired. If a cushion or blotter layer is required in the design between the vapor barrier and the slab, additional care should be taken, especially if sharp crushed rock is used. Washed rock will provide less chance of damage during placement.These are very general installation instructions. Instructions on architectural or structural drawings should be reviewed and followed.

APPLICATION TO SUBSTRATECarefully align and unroll Viper Double Bond Tape to substrate. Do not remove release paper until vapor barrier is ready to be installed. This prevents dirt, dust, debris and other foreign objects from interfering with adhesive.

APPLICATION TO TAPEThe release film should not be removed until the moment you are ready to adhere to Viper Double Bond Tape. Never leave Viper Double Bond Tape uncovered once the release film has been removed. This prevents dirt, dust, debris and other foreign objects from interfering with adhesive. Do not leave Viper Double Bond Tape uncovered for more than 8 hours.

When mechanical fasteners are required for permanent holds, such as termination bars, it is suitable to fasten through the Viper Double Bond Tape. The Viper Double Bond Tape will self seal around the fasteners creating a gasket between the substrate and material being fastened.

SPECIAL INSTRUCTIONSIf Viper Double Bond Tape is to be left exposed for an extended period of time, be sure to cover with UV resistant material as Viper Double Bond Tape is not designed for prolonged exposure to direct sunlight. Store Viper Double Bond Tape in the carton and remove only as needed. Store carton of Viper Double Bond Tape on end in a dry place at temperatures not exceeding 100° F (38° C).

VAPORCHECK® MASTIC is 100% free of VOCs, HAPs and Asbestos.

4.3 Physical Properties:

VAPORCHECK® MASTIC is a latex modified asphalt clay emulsion with polymers and colloids to formulate a waterproof coating. The gel consistency of this material allows for a heavy coating to be applied to steep or vertical surfaces with no sagging or running. VAPORCHECK® MASTIC forms an impervious moisture barrier that is not affected by normal alkali or acids found in soils.

5.0 INSTALLATION

5.1 Substrate Preparation:

The surface to which VAPORCHECK® MASTIC is applied must be structurally sound, clean, dry and free of dust, mud, loose mortar, sand, soil, frost or other loose materials. Dry or dusty surfaces should be hosed or mopped clean with water. VAPORCHECK® MASTIC is recommended to be applied to dampened surfaces for better adhesion.

5.2 Application Temperature: VAPORCHECK® MASTIC should NOT be applied if rain is eminent or during cold weather below 50°F (10°C). VAPORCHECK® MASTIC cures in about 24 hours depending on the temperature and humidity.

5.3 Application Procedure:

NOTE: VAPORCHECK® MASTIC needs to be stirred prior to use.

For pipe and rebar penetrations cut and install Viper under-slab vapor barriers tightly to penetration. Apply VAPORCHECK® MASTIC around penetration and over any exposed sub-surface.

For larger openings around penetrations, first install self-adhering VIPER® VAPORPATCH. Then seal remaining exposed areas with VAPORCHECK® MASTIC. Doing so provides a structurally sound, clean and dry area of adhesion to ensure a complete seal around the penetration.

VAPORCHECK® MASTIC has a thick consistency and should be applied by trowel or putty knife around all penetrations in one or two coats. It is recommended that VAPORCHECK® MASTIC be applied to an application thickness of 60 mils wet, which will yield 40 mils dry. These yields equate to an application rate of 25 square feet per gallon. The coating will be dry to the touch within 10 minutes, but should be allowed to cure for 4 to 24 hours after installation.

DO NOT backfill or cover for 24 hours after installation. DO NOT allow more than 10 days to elapse before covering.

NOTE: VAPORCHECK® MASTIC is self priming and does not require the use of a primer. It has been tested compatible with all ABAA certified transition membranes and can be applied below and/or above these membranes.

5.4 Surface Temp. & Chemical Resistance:

VAPORCHECK® MASTIC is resistant to chemical attack and is very resistant to acids and salts. It should not be applied on surfaces that exceed 210ºF.

5.5 Clean Up & Disposal:

VAPORCHECK® MASTIC can be cleaned while wet with soap and water. If the VAPORCHECK® MASTIC has cured; it can be removed with mineral spirits.

NOTE: DO NOT re-use container. DO NOT contaminate water, food or feed by storage or disposal. The open dumping of the container is prohibited. Consult Federal, State or Local disposal authorities for approved alternate procedures.

5.6 Storage & Limitations:

• DO NOT allow material to freeze.• DO NOT thin the material.• DO NOT heat material over 160ºF.

Viper Under-Slab Vapor Barrier

Note: VaporCheck Mastic is suitable for both Viper VaporCheck and Viper VaporCheck II under-slab vapor retarders and barriers. The “Orange” color is used for detail purposes only.





17

Note: The following installation instructions are based off of ASTM E 1643 (Standard Practice for Installation of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs).

1. Install Viper Vapor Barrier over compacted base material. Viper Vapor Barriers are designed to withstand rugged construction environments; therefore it is not necessary to have a perfectly smooth subsurface.

2. Unroll Viper Vapor Barrier with the longest dimension parallel with the direction of the concrete pour. The Viper Vapor Barrier should completely cover the entire pour area.

3. Extend Viper Vapor Barrier over footings and seal to foundation wall, grade beam, or slab at an elevation consistent with the top of the slab or terminate at impediments such as water stops or dowels. (Refer to slab on grade detail).

4. All joints and seams should be overlapped a minimum 6 inches and sealed with 4 inch White Polyethylene Viper Vapor Tape and/or 2 inch Viper Double Bond Tape. (Note: The area of adhesion should be free from dust, dirt and moisture to allow for maximum adhesion of the tape).

5. All penetrations such as utilities and columns should be sealed using Viper Vapor Barrier, Viper VaporPatch and/or VaporCheck Mastic. Doing so creates a monolithic membrane between the surface of the slab and moisture sources below the slab. (Refer to Boot and Patch Details).

6. If Viper Vapor Barrier becomes damaged during or after installation, repairs must be made. Methods of repair include:

A. Create patch using roll of Viper VaporPatch. Peel off release backing and adhere over damaged area (Refer to Boot and Patch Details).

B. Cut a piece of Viper Vapor Barrier large enough to extend 6 inches beyond damaged area on all sides. Secure patch with either 4 inch White Polyethylene Viper Vapor Tape and/or 2 inch Viper Double Bond Tape. (Note: The area of adhesion should be free from dust, dirt and moisture to allow for maximum adhesion of the tape).

7. A secondary protective layer, such as fine washed gravel or sand is not necessary. If used, do so in accordance with American Concrete Institute’s ACI 302 guidelines.

�� / APRIL 2003 85

BY BRUCE A. SUPRENANT

W hen preparing construction documents forconcrete slabs that will receive moisture-

sensitive floor coverings, specifiers must considerboth the benefits and liabilities of any decisions theymake regarding:■ Vapor retarders;■ Concrete materials and properties;■ Concrete surface properties; and■ Protection of the floor surface.

The decisions require compromises—as do mostdesign decisions.

� �� Vapor retarder location is a critical decision, but

material, thickness, and installation methods also mustbe considered.

��

Most specifiers require the vapor retarder to conformto ASTM E 1745 “Standard Specification for Plastic WaterVapor Retarders Used in Contact with Soil or Granular

Design of Slabsthat Receive

��

Part 2: Guide to Specification Issues for Architects and Engineers

Fill under Concrete Slabs.”1 This standard requires specifica-tions for vapor-retarder materials to include the following:■ This specification number (E 1745);■ Class A, B, or C, or alternatively, specific performance

requirements for each of the properties (watervapor permeance, tensile strength, and punctureresistance); and

■ Performance requirements, if any, for special conditions(flame spread, permeance after soil poison petroleumvehicle exposure, and permeance after exposure toultraviolet light).Class A, B, and C vapor retarders must all have the

same 0.3-perm water vapor permeance but have to meetdiffering tensile strength and puncture resistancerequirements. Class A has the highest strength andpuncture resistance and Class C has the lowest.

��

ACI 302.1R-96, “Guide for Concrete Floor and SlabConstruction,”2 gives the following recommendation forvapor retarder thickness:

29

86 APRIL 2003 / ��

“Although polyethylene film with a thickness of aslittle as 6 mils has been satisfactory as a vapor retarder,the committee strongly recommends that a thickness ofnot less than 10 mils be used. The increase in thicknessoffers increased resistance to moisture transmissionwhile providing more durability during and after itsinstallation.”

Tests confirm that a 10-mil thickness provides reasonabledurability during and after installation when the vaporretarder is placed under a granular fill.3 When the vaporretarder isn’t protected by a fill, some specifiers requirea 20-mil thickness, or greater. Use of a vapor barrierinstead of a vapor retarder may be appropriate whenthere is a risk of damage caused by construction traffic.

��

Some specifiers require concrete to be placed directlyon the vapor retarder. Others require placement of a

granular blotter layer between the concrete and thevapor retarder. Choosing a location that minimizeswater-vapor movement may result in finishing delaysand an increased chance of curling or cracking. 4,5

Recently, ACI Committees 302 and 360 published a“Flowchart for Location of Vapor Retarder/Barrier”6 thatis now a part of ACI 302.1R-96 (Fig. 1). Based on theflowchart, concrete slabs to receive a moisture-sensitivefloor covering should be placed directly on the vaporretarder. The committee provides the following explanation:

“Based on the review of the details of probleminstallations, it became clear that the fill course abovethe vapor retarder can take on water from rain, wet-curing, wet-grinding or cutting, and cleaning. Unable todrain, the wet or saturated fill provides an additionalsource of water that contributes to moisture-vaporemission rates from the slab well in excess of the3 to 5 lb/1000 ft2/24 h recommendation of the floor

covering manufacturers.“As a result of these experiences,

and the difficulty in adequatelyprotecting the fill course from waterduring the construction process,caution is advised on the use of thegranular fill layer when moisture-sensitive finishes are to be appliedto the slab surface.

“The committees believe that whenthe use of a vapor retarder or barrieris required, the decision whether tolocate the retarder or barrier in directcontact with the slab or beneath alayer of granular fill should be madeon a case-by-case basis.

“Each proposed installation shouldbe independently evaluated byconsidering the moisture sensitivityof subsequent floor finishes, anticipatedproject conditions and the potentialeffects of slab curling and cracking.

“The following chart can be usedto assist in deciding where to placethe vapor retarder. The anticipatedbenefits and risks associated with thespecified location of the vapor retardershould be reviewed with all appro-priate parties before construction.”

Some specifiers require placingthe vapor retarder directly under theconcrete slab even if initial plans forthe building don’t call for a moisture-sensitive floor covering. They reasonthat if such a floor covering is addedin the future, there is no way to post-install a vapor retarder.Fig. 1: Flowchart for Location of Vapor Retarder/Barrier (Ref. 6)

30

�� / APRIL 2003 87

��

Most specifiers require that the vapor retarder beinstalled in accordance with ASTM E 1643 “StandardPractice for Installation of Water Vapor Retarders Used inContact with Earth or Granular Fill Under ConcreteSlabs.” Referencing this document requires the contractorto follow the manufacturer’s instructions for placement(including laps and sealing around penetrations andfoundation walls), protection, and repair.

ASTM E 1643 requires the contractor to use reinforcementsupports that don’t puncture the vapor retarder and torepair any damaged areas. Effects of holes in a vaporretarder have been measured.7 A 5/8-in.-diameter (16mm) stake hole in 8-mil-thick polyethylene sheet overwet sand allowed a water-vapor emission rate of about3.0 lb/1000 ft2/24 h.

�� There is much speculation—but not much published

data—about effects of concrete materials and propertieson moisture-vapor emission. Two studies—Brewer8 in1965 and Suprenant and Malisch9 in 1998—producedexperimental data on concrete moisture emission.Brewer’s moisture flow data were originally reported asgrains/ft2/h but have been converted to a measurecommonly used today— lb/1000 ft2/24 h. 10

Brewer tested 141 specimens made from 29 differentconcrete mixtures that were moist cured for 7 days. Water-cement ratios (w/c) by weight ranged from 0.4 to 1.0. The4-in.-thick (100 mm) concrete specimens were weighedas they dried with the following exposures: bottomsealed, bottom exposed to water vapor, and bottom incontact with water. As expected, concrete specimensexposed to water vapor or in contact with water dried ata much slower rate. Because it’s recommended that forfloors to receive moisture-sensitive flooring, concreteshould be placed directly on a vapor retarder, this articlereviews Brewer’s data for bottom-sealed specimens.

Specifiers should be familiar with a number of ASTMstandards and some other common references withinthe floor-covering industry. These references aresometimes cited in project specifications, but should becarefully read before they’re cited. Some may not beappropriate for a particular project, and others may notcontain up-to-date information. They can, however,often provide a reasonable method of deliveringinformation to the contractor and product suppliers.

Suprenant and Malisch tested 2-, 4-, 6-, and 8-in.-thick(50, 100, 150, and 200 mm), 3-ft-square concrete slabsmade with w/c of 0.31, 0.37, and 0.40 and cured underplastic sheeting for 3 days. They measured water-vaporemission in accordance with ASTM F 1869, “Standard TestMethod for Measuring Moisture Vapor Emission Rate ofConcrete Subfloor Using Anhydrous Calcium Chloride.”

�!!��!�$%&��$��%��%��

Brewer tested concretes with 300 to about 700 lb/yd3

(178 to 415 kg/m3) of ASTM Type I cement. Differingmixtures contained admixtures that included two air-entraining agents, two calcium chloride solutions, butylstearate, and two water-reducing admixtures (lignosul-fonate and hydroxylated carboxylic acid).

Suprenant and Malisch tested concretes with about600 to 700 lb/yd3 (356 to 415 kg/m3) of ASTM Type I/IIcement, a nonchloride accelerator, and a mid-rangewater reducer. One mixture contained Class F fly ash.

Neither study produced datashowing that the presence of anadmixture altered concrete dryingor water-vapor emission rates. Oneof Brewer’s conclusions was that“…on the basis of concretes withequal water-cement ratios, theadmixtures used neither contributedto, nor detracted from, the measuredvalues to any appreciable degree.”On the other hand, Hedenblad foundthat using 10% silica fume by weightof cement could shorten dryingtime by about 2 weeks for a w/c of0.45 and by about 4 weeks for aw/c of 0.50.11

Hedenblad’s studies also producedtest results showing that air entrain-ment, rapid hardening cement, andsuperplasticizers had little effect onconcrete drying time.11 He noted that“drying largely occurred in the sameway as for concrete without super-plasticizer admixture and with thesame w/c ratio.” 11

Based on the available data, thereis no reason to specifically includeor exclude the use of any admixturesor high-early-strength cements as away of influencing concrete dryingor moisture emission rates. There issome evidence that concretescontaining silica fume dry fasterthan concretes without silica fume.

��'��'��

Brewer tested concretes with air contents between1 and 7%, slumps from 1-1/2 to 8 in. (40 to 200 mm),densities from 139 to 154 lb/ft3 (2230 to 2470 kg/m3), andcompressive strengths from 1300 psi to slightly over8000 psi (9 to 55 MPa). Suprenant and Malisch testedconcretes with air contents between 1.8 and 2.3%,slumps from 7 to 9-1/2 in. (175 to 240 mm), densities from147 to 148 lb/ft3 (2350 to 2370 kg/m3), and compressivestrengths from 7000 to 8000 psi (48 to 55 MPa).

Neither study produced data showing a relationshipbetween measured concrete properties and concretedrying or water-vapor emission rates.

(��%��

Water-cement ratio has a significant effect on moisturemigration through concrete slabs. Figure 2, derivedprimarily from Brewer’s original work, clearly shows thatthe time required to reach a given water-vapor emissionrate depends on w/c. Table 1 shows the interpolated

drying time, in days, needed to reach 3 lb/1000 ft2/24 hfor a 4-in.-thick (100 mm) specimen exposed to anenvironment of 73 °F (23 °C) and 50% relative humidity.12

Table 1 indicates that for concrete with a w/c of 0.40, adrying time of 46 days was needed to produce thecommonly specified water-vapor emission rate of 3 lb/1000 ft2/24 h. This matched the drying time Suprenantand Malisch determined for concrete with a w/c of 0.40and exposed to an environment of 70 °F (21 °C) and 28%relative humidity. They found no additional advantage inusing concretes with lower w/c. Concretes with lowerw/c dried at the same rate as concrete with the 0.40 w/c.

ASTM F 710, “Standard Practice for Preparing ConcreteFloors to Receive Resilient Flooring,” contains w/c recom-mendations in the Appendix (nonmandatory information):

“Moderate to moderately low water-cement ratios(0.40 to 0.45) can be used to produce floor slabs that caneasily be placed, finished, and dried, and which will haveacceptable permeability to moisture. Floor slabs withwater-cement ratios above 0.60 take an exceedingly longtime to dry and cause adhesives or floor coverings, orboth, to fail due to high moisture permeability.

“A 4-inch thick slab, allowed to dry from only one side,batched at a water-cement ratio of 0.45, typically requiresapproximately 90 to 120 days to achieve a moisturevapor emission rate (MVER) of 3 lb/1000 ft2 per 24 h(the resilient flooring industry standard MVER). Theimportance of using a moderate to moderately low water-cement ratio for floors to receive resilient flooringcannot be overemphasized.”

Water-cementitious material ratio (w/cm) of 0.40 to0.45 will typically produce concretes with compressivestrengths of 4500 to 5000 psi (31 to 34 MPa). Thesestrengths are likely to increase the potential for shrinkage,curling, and cracking. If a short concrete drying time iscritical, a w/cm of 0.40 to 0.45 is needed. However, aconcrete drying time of about 3 months is often suitablefor construction projects. This time can be achievedusing concrete with a 0.50 w/cm. Such a concrete is moreeconomical, has enough paste for finishing, and makesit easier to satisfy other specification requirementsrelated to surface finish and flatness. Water-reducing ormid-range water-reducing admixtures can be used toproduce this concrete.

Requiring a w/cm of 0.50 is typically equivalent torequiring a specified compressive strength, ƒ′

c, of 4000 psi

(28 MPa). Don’t specify a w/cm without specifyingthe corresponding compressive strength. ACI coderequirements don’t usually govern design and constructionof soil-supported slabs, but the following quote from thecode commentary should be noted:

“Selection of an ƒ′c that is consistent with the water-

cementitious materials ratio selected for durability willhelp ensure that the required water-cementitiousmaterials ratio is actually obtained in the field.”

This indicates that compressive strength tests can beused to verify the w/cm. Field measurements of w/cm forfresh concrete aren’t reliable enough for use in assuringthat the specified value has been achieved.

��)��

In addition to testing normalweight concrete,Suprenant and Malisch also tested a lightweight concretewith a w/cm of 0.40. 13 Normalweight concrete with a 0.40w/cm reached an emission rate of 3 lb/1000 ft2/24 h in46 days. Lightweight concrete with a w/cm of 0.40 took183 days to dry to the same emission rate. The testresults for lightweight concrete were validated by fieldmeasurements for a structure in which the lightweightconcrete took more than 6 months to dry.14 Specifiersshould realize that obtaining the benefits of lightweightconcrete may also result in significantly longer concretedrying times.

��*��!!��

A common rule of thumb for drying time has been“one month for each inch (25 mm) of slab thickness.”Suprenant and Malisch measured changes in water-vaporemission values with time for 2-, 4-, 6-, and 8-in.-thick(50, 100, 150, and 200 mm) slabs of concrete with threedifferent w/cm values. 9 Regardless of the thickness,water-vapor emissions decreased at about the same rate.Based on these test results, reducing slab thicknesswon’t reduce required drying times.

�#�� Concrete properties at the floor surface affect two

factors related to adhesive performance—moisturecontent and pH.

��!!��

Because cement hydration immobilizes some of themixing water, well-cured concrete contains less freewater that must evaporate before floor coverings can beapplied. But the disconnected void system in well-curedconcrete slows movement of liquid or gaseous water.Drying well-cured concrete thus requires removing asmall amount of water that must exit the concretethrough a winding, constricted path. Which is preferred:a well-cured concrete with little free water but a difficultpath to escape, or concrete with more free water thatcan escape through an easier path?

Experimental work by Hedenblad11 and Jackson andKellerman15 shows that less curing produces faster drying.Hedenblad’s experimental work indicates that a 28-day cureinstead of a 1-day cure increases the required drying timeby about 1 month. Suprenant and Malisch16 and Kanare17

recommend using plastic sheeting to cure the concretefor 3 days. This provides a compromise between improvingthe concrete properties and decreasing the drying time.

33

90 APRIL 2003 / ��

Many specifiers require watercuring for floors—sometimes as longas 28 days. This practice is counter-productive for floors that must drybefore flooring materials are in-stalled. It delays the start of drying,adds water that must later exit theconcrete, and further constricts thepath through which the water mustexit. If drying time is critical to theschedule, don’t specify water curingor curing times longer than 7 days.

��!��!��

When floors will receive coverings,most specifiers require a light powertrowel finish with a light broomtexture. Don’t specify a burnishedfinish, as the surface will be toodense to be marked with a broom.Also, expect some wearing of thebroom finish by the time the floor covering is applied.

There is some anecdotal evidence that concrete witha power-trowel finish dries more slowly than concretewithout a power-trowel finish. In the troweling process,the surface is compacted and densified, apparentlymaking it more difficult for water to evaporate. Wherepossible, consider specifying a bullfloat, straightedge,and broom finish.

�!!��!�'+

ASTM F 710 provides a summary of surface pHchanges with age:

“As Portland cement hydrates, calcium hydroxide andother alkaline hydroxides are formed. The pH of wetconcrete is extremely alkaline, typically around pH of 12to 13. The surface of concrete will naturally react withatmospheric carbon dioxide to produce calcium carbonatein the hydraulic cement paste, which reduces the pH ofthe surface. Results in the range of pH 8 to 10 are typicalfor a floor with at least a thin layer of carbonation(approximately 0.04 inch).”

A totally carbonated layer of concrete has a pH ofabout 8.3.18 However, not all concrete will carbonate to apH as low as 8.3. Measurements by several researchersindicate that the pH in the carbonated layer may drop toonly about 10.5. The concrete slabs tested by Suprenantand Malisch had a pH of 9 after about 3 months of drying. 9

A specified pH less than 10 may require acid etching.This is unlikely to be a good solution, as the acid mustthen be rinsed from the concrete surface. Adding rinsewater rewets the surface and increases the neededdrying time. Because of this, you should specify a floor-covering adhesive that is suitable for use with a substratepH of 9 or 10 and doesn’t require acid etching.

��!��'��'��

Regardless of the floor covering or adhesivemanufacturer’s instructions, no surface preparationshould be allowed without authorization of the architector engineer. ASTM F 710 states that “abrasive removal(shotblasting, sanding, or grinding) of a thin layer ofconcrete can remove [the] carbonated layer and exposemore highly alkaline concrete below. Additional pH tests,waiting time, application of patching compound orunderlayment, or a combination thereof, might berequired after abrasive removal of the concrete surface.”

Unpublished test results by Suprenant and Malischconfirm this. They measured a pH of 9 on dried testslabs, then removed a thin layer of concrete surface bysandblasting. Measurements made immediately after thesandblasting yielded a pH of 12.

Some flooring manufacturers recommend cleaning orpreparing the concrete surface by pressure washing.This adds additional water, and can raise the pH if someof the concrete surface is removed.

Most concrete slabs don’t require surface preparationfor the adhesive to bond. Tensile strengths of concretesurfaces often exceed 100 psi (0.7 MPa). Most floor coveringadhesives, unless made with epoxy, pull off at 20 to 30 psi(0.14 to 0.28 MPa). Specifying a light broom finish shouldallow skipping the manufacturer’s surface preparationrecommendations. If there’s a question about the effect ofsurface condition on adhesive bond, have a testing labmeasure the tensile pull-off strength of the concrete surfaceand of the adhesive used for the floor covering.

Concrete surface repairs can have an adverse effecton flooring-adhesive bond. If the repairs involve grinding

or shotblasting, the low pH could be lost. If the repairsinvolve the use of patching or underlayment materials,these need to dry after placement. Some floor repairproducts reportedly dry quickly, and may be useful forweekend repairs to existing facilities.

�� When drying time is critical to the schedule, it’s

important to protect the slab from external moisturesources. External sources include rainwater, runoff fromadjacent slopes, landscaping water, and water fromcuring or other construction activities such as wet-grinding, sawing, and cleaning.

Figure 3 shows the effects of rewetting on water-vaporemission rates. Low-w/c concrete took 46 days to reachan emission rate 3 lb/1000 ft2/24 h. Adding water to thesurface after the 46-day drying period increased theemission rate to 15 lb, and five more weeks of dryingwere required to return to 3 lb. A second rewetting atthis point increased the emission rate to 8 lb, after whichit returned to 3 lb in 2 weeks.

Hedenblad found that rewetted mature concrete driesmuch more slowly than newly placed concrete.19 Tosimulate mature concrete, he tested concrete slabs thatwere more than a year old. Rewetted mature concretewith a w/c of 0.70—and drying from one side only—took515 days to reach an internal relative humidity target. Toreach the same internal relative humidity, newly placedconcretes with a 0.70 w/c took 184 days when cured for1 day and 258 days when cured for 4 weeks.

When drying time is critical and the moisture-sensitivefloor covering is an important feature of the facility, theslabs should be constructed after the building is en-closed and the roof is watertight. Typically, this extendsthe construction schedule and increases costs, but thesedisadvantages must be weighed against a 1- or 2-monthschedule delay that’s likely if the floors are rained on.
