Designation:D810917Standard Guide forWaterproofing Repair of Concrete by Chemical Grout CrackInjection1This standard is issued under the fixed designation D8109;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 describes the selection of materials,installa-tion methods,and inspection required for sealing leaks atcracks in concrete building walls and slabs using chemicalgrout.The process discussed in this guide is a waterproofingrepair in which voids in a concrete element are sealed with areactive solution,installed by pressurized injection throughdrilled or surface-mounted ports.1.2 This guide does not address the use of chemical groutfor waterproofing by curtain grouting or injection into pre-placed permeable waterstop tubes.Injection of masonry ele-ments presents additional factors beyond the scope of thisguide.This guide does not address the use of injectablematerials for structural repairs,or for geotechnical applicationssuch as soil stabilization.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 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.1.5 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:2F2304 Practice for Sealing of Sewers Using ChemicalGroutingF2414 Practice for Sealing Sewer Manholes Using ChemicalGroutingF2454 Practice for Sealing Lateral Connections and linesfrom the mainline Sewer Systems by the Lateral PackerMethod,Using Chemical Grouting2.2 International Concrete Repair Institute(ICRI)3Guideline No.340.1 Guide for the Selection of Grouts toControl Leakage in Concrete Structures2.3 U.S.Army Corps of Engineers:4Manual No.1110-1-3500 Chemical Grouting2.4 U.S.Department of the Interior,Bureau of Reclama-tion:5Leaking Crack Repair Using Chemical Grouts3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 acrylamide,norganic solid of white,odorless,acrylic resinous material available in flake-like crystals and inliquid form.3.1.2 acrylate,na general term applied to various water-soluble acrylic resinous materials.3.1.3 acrylic resin,na type of resin polymerized fromacrylic acid,methacrylic acid,esters of these acids,or acrylo-nitrile.3.1.4 chemical grout,ninjection repair media other thanparticulate or cementitious grout that may be multi-component,with or without additives,and based on either polyurethaneresin or acrylic resin.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.1,2017.Published December 2017.DOI:10.1520/D8109-17.2For 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 the International Concrete Repair Institute(ICRI),10600 WestHiggins Road,Suite 607,Rosemont,IL,60018,www.icri.org.4Available from the U.S.Army Corps of Engineers,www.publications.usace.army.mil.5Available from U.S.Department of the Interior,Bureau of Reclamation,www.usbr.gov/research/projects.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 3.1.5 cohesion,nthe state in which the constituents of amass of material are held together by chemical and physicalforces.3.1.6 control agent,nsubstance added which controls theviscosity or flow properties of the material it is added to.3.1.7 curtain grouting,ninjection of grout into a sub-surface formation in such a way as to create a barrier of groutedmaterial transverse to the direction of the anticipated waterflow.A grout curtain on the positive side of the leakingsub-gra
