Designation:C898/C898M09Standard Guide forUse of High Solids Content,Cold Liquid-AppliedElastomeric Waterproofing Membrane with SeparateWearing Course1This standard is issued under the fixed designation C898/C898M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide describes the use of a high solids content,cold liquid-applied elastomeric waterproofing membrane thatmeets the criteria in Specification C836,in a waterproofingsystem subject to hydrostatic pressure for building decks overoccupied space where the membrane is covered with a separateprotective wearing course.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C33 Specification for Concrete AggregatesC578 Specification for Rigid,Cellular Polystyrene ThermalInsulationC717 Terminology of Building Seals and SealantsC836 Specification for High Solids Content,Cold Liquid-Applied Elastomeric Waterproofing Membrane for Usewith Separate Wearing CourseC920 Specification for Elastomeric Joint SealantsC1193 Guide for Use of Joint SealantsC1299 Guide for Use in Selection of Liquid-Applied Seal-ants(Withdrawn 2012)3C1471 Guide for the Use of High Solids Content ColdLiquid-Applied Elastomeric Waterproofing Membrane onVertical SurfacesC1472 Guide for Calculating Movement and Other EffectsWhen Establishing Sealant Joint WidthD1056 Specification for Flexible Cellular MaterialsSponge or Expanded RubberD1751 Specification for Preformed Expansion Joint Fillerfor Concrete Paving and Structural Construction(Nonex-truding and Resilient Bituminous Types)D1752 Specification for Preformed Sponge Rubber Corkand Recycled PVC Expansion Joint Fillers for ConcretePaving and Structural ConstructionD5295 Guide for Preparation of Concrete Surfaces for Ad-hered(Bonded)Membrane Waterproofing SystemsD5957 Guide for Flood Testing Horizontal WaterproofingInstallationsD6134 Specification for Vulcanized Rubber Sheets Used inWaterproofing SystemsD6451 Guide for Application of Asphalt Based ProtectionBoardD6506 Specification for Asphalt Based Protection Board forBelow-Grade WaterproofingE1907 Guide to Methods of Evaluating Moisture Conditionsof Concrete Floors to Receive Resilient Floor Coverings(Withdrawn 2008)32.2 American Concrete Institute Standard:ACI 301 Specifications for Structural Concrete for Build-ings43.Terminology3.1 For definitions of terms used in the guide,refer toTerminology C717.3.2 Definitions of Terms Specific to This Standard:1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.22 on Water-proofing and Dampproofing Systems.Current edition approved June 15,2009.Published July 2009.Originallyapproved in 1978.Last previous edition approved in 2001 as C898 01.DOI:10.1520/C0898_C0898M-09.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from ACI International,P.O.Box 9094,Farmington Hills,MI4833-9094.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.1 cold-appliedcapable of being applied without heat-ing as contrasted to hot-applied.Cold-applied products arefurnished in a liquid state,whereas hot-applied products arefurnished as solids that must be heated to liquefy them.3.2.2 curing timethe period between application and thetime when the material reaches its design physical properties.3.2.3 deflectionthe deviation of a structural element fromits original shape or plane due to physical loading,temperaturegradients,or rotation of its supports.3.2.4 drainageboardseeprefabricateddrainagecomposite,the preferred term.3.2.5 drainage coursesee percolation layer and Fig.1.3.2.6 flashinga generic term describing the transitionalarea between the waterproofing membrane and surfaces abovethe wearing surface of the building deck;a terminal closure orbarrier to prevent ingress of water into the system.3.2.7 freeze-thaw cyclethe freezing
