Designation:D595798(Reapproved 2021)Standard Guide forFlood Testing Horizontal Waterproofing Installations1This standard is issued under the fixed designation D5957;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides the user with a method for testingthe watertightness of waterproofing installations applied tohorizontal surfaces having a slope not greater than 20 mm/m(2%slope)(14in.per ft).1.2 This guide is intended for waterproofing installation onparking garages and plaza deck type applications over habit-able spaces or on elevated structures,but is not intended for useon building roofing systems.Applicable waterproofing mem-brane installations that may be tested using this guide are fullyadhered or bonded sheet membranes,liquid or fluid-appliedmembranes,or loose-laid sheet membranes.1.3 The procedures presented here are not intended for useon those waterproofing installation applications that are forlong-termwaterstorageorcontinuouslysubmergedenvironments,such as swimming pools,fountains,tank linerswith hydrostatic pressure,or water storage units(storageperiod greater than 48 h).1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 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.1.6 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 Waterproofing2.2 ACI Document:3ACI 515 Guide to the Use of Waterproofing,Dampproofing,Protective,and Decorative Barrier Systems for Concrete3.Terminology3.1 For definitions of terms relating to roofing andwaterproofing,see Terminology D1079.3.2 Definitions of Terms Specific to This Standard:3.2.1 sacrificial sheeta material used to form a temporaryseal between a containment assembly and the waterproofingsystem.The material used for a sacrificial sheet shall not causedamage nor be detrimental to the primary system.4.Summary of Guide4.1 This guide uses a series of temporary containmentassemblies of pond water on horizontal surfaces to determinethe watertightness of waterproofing installations.4.2 The area to be tested is subdivided as required by thecontainment assemblies,and drains within the subdivided areaare temporarily blocked to prevent water leakage into thedrainage system.4.3 Water is ponded in the subdivided area and maintainedfor a minimum period of 24 h.The space below the testlocation is monitored for leakage during the test period.5.Significance and Use5.1 This guide describes the techniques used to test forwatertightness of waterproofing installations on horizontalservices having a slope not greater than 20 mm/m(2%slope)(14in./ft).See also ACI 515.1This 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 Dec.1,2021.Published December 2021.Originallyapproved in 1996.Last previous edition approved in 2013 as D5957 98(2013).DOI:10.1520/D5957-98R21.2For 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.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?5.2 The structural capacity of the substrate to which thewaterproofing system is to be installed should be reviewed bya licensed structural engineer to verify that the loads associatedwith the use of procedures described in this guide do notexceed code and design restrictions.Lateral loads will beimposed on curbs or walls used for containment of the waterduring the test procedures and their effect should be accountedfor.T
