Designation:D5295/D5295M18Standard 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.NOTE1Once installed,it is difficult to visually identify the differencebetween normal weight and lightweight concrete.It is recommended thata review of contract documents,concrete batch or delivery tickets orsimilar effort be performed to identify the concrete type.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD4258 Practice for Surface Cleaning Concrete for CoatingD4262 Test Method for pH of Chemically Cleaned or EtchedConcrete SurfacesD4263 Test Method for Indicating Moisture in Concrete bythe Plastic Sheet MethodF2659 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.310.2R(2013)Concrete Sur-face Preparation for Sealers,Coatings,and Polymer Over-lays3.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 mechanical,chemical,and blast1This 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 March 1,2018.Published March 2018.Originallyapproved in 1992.Last previous edition approved in 2014 as D5295/D5295M 14.DOI:10.1520/D5295_D5295M-18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 cleaning methods in order to provide good adhesion betweenthe waterproofing system and the concrete as well as the effectand control of various surface contaminants.It also addressesthe evaluation
