Designation:D5295/D5295M14Standard Guide forPreparation of Concrete Surfaces for Adhered(Bonded)Membrane Waterproofing Systems1This standard is issued under the fixed designation D5295/D5295M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides recommendations for the prepara-tion of concrete surfaces prior to the application of adhered(bonded)waterproofing.1.2 This guide is directed primarily toward installations ofnew concrete,but is also applicable for existing concreteinstallations.(See also ACI 116 and ACI 546.)1.3 This guide does not apply to loose laid systems,ben-tonite systems,lead,or the like.1.4 This guide does not apply to applications involvinginsulating concrete.1.5 This guide does not apply to applications involvinglightweight structural concrete.1.6 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.1.7 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:2D1079 Terminology Relating to Roofing and WaterproofingD4262 Test Method for pH of Chemically Cleaned or EtchedConcrete SurfacesD4263 Test Method for Indicating Moisture in Concrete bythe Plastic Sheet MethodF2420 Test Method for Determining Relative Humidity onthe Surface of Concrete Floor Slabs Using RelativeHumidity Probe Measurement and Insulated HoodF2659 Guide for Preliminary Evaluation of ComparativeMoisture Condition of Concrete,Gypsum Cement andOther Floor Slabs and Screeds Using a Non-DestructiveElectronic Moisture Meter2.2 ACI Standards:3ACI 116 Cement and Concrete TerminologyACI 301 Specifications for Structural Concrete for Build-ingsACI 311 Guide to Inspection of ConcreteACI515A GuidetotheUseofWaterproofing,Dampproofing,Protective and Decorative Barrier Systemsfor ConcreteACI 546 Repair of Concrete2.3 ICRI Standard:4ICRI Technical Guideline No.310.2 Concrete SurfacePreparation for Sealers,Coatings,and Polymer Overlays3.Significance and Use3.1 The success of a waterproofing application depends on,among other things,the type,smoothness,and cleanliness ofthe concrete surface being coated.This guide describes condi-tioning or repairing of the concrete surface by the removal orother constructive modification of those surface defects thatcan affect the performance of the waterproofing system.Itcovers surface preparation by chemical and blast cleaningmethods in order to provide good adhesion between thewaterproofing system and the concrete as well as the effect andcontrol of various surface contaminants.It also addresses theevaluation of concrete moisture content to ensure optimalinitial bond.(See also ACI 515.)3.2 This guide is not intended to offer guidelines for theselection of a suitable waterproofing system;the use of specific1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofingand is the direct responsibility of Subcommittee D08.22 on Water-proofing and Dampproofing Systems.Current edition approved July 1,2014.Published August 2014.Originallyapproved in 1992.Last previous edition approved in 2006 as D5295 00(2006).DOI:10.1520/D5295_D5295M-14.2For 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.3Available from American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333.4Available from International Concrete Repair Institute(ICRI),10600 WestHiggins Rd.,Suite 607,Rosemont,IL 60018,www.icri.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 application techniques;or the design and installation offlashing,terminations,expansion joint details,etc.(For defini-tions of terms,see Terminology D1079.)3.3 This guide is not intended to offer guidelines for thecontrol of water vapor drive through the concrete which couldaffect long term performance of the bond between the concreteand waterproofing.3.4 The recommended procedures described herein areminimums;the waterproofing materials manufacturer mayrequire more strict or specific procedures for the preparation ofconcrete surfaces for the application of the manufacturersspecific system.4.Adhesion Inhibitors4.1 GeneralAmong the item
