Designation:F241404(Reapproved 2009)Standard Practice forSealing Sewer Manholes Using Chemical Grouting1This standard is issued under the fixed designation F2414;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 practice covers proposed selection of materials,installation techniques,and inspection required for sealingmanholes using chemical grout.Manholes or sections ofmanholes with active leaks shall be repaired.Manholes to begrouted are of brick,block,cast-in-place concrete,precastconcrete,or fiberglass construction.Manholes or sections ofmanholes with active leaks will be designated by the engineer,owners representative,or authorized inspector,for manholegrouting.1.2 The contractor shall be responsible for furnishing alllabor,supervision,materials,equipment,and inspectionfollow-up required for the completion of chemical grouting ofmanhole defects in accordance with the contract documents.1.3 Materials,additives,mixture ratios,and proceduresutilized for the grouting process shall be in accordance withmanufacturers recommendations and shall be appropriate forthe application.1.4 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.1.5 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 acrylamideorganic solid of white,odorless,acrylicresinous material available in flake-like crystals and in liquidform.The greatest use of acrylamide is as a coagulant aid indrinking water treatment.Other major uses of acrylamide arein soil stabilization,in grout for repairing sewers and inacrylamide gels used in biotechnology laboratories.2.1.2 acrylatea general term applied to various water-soluble acrylic resinous materials.2.1.3 authorized inspectorthe person(s)contracted or ap-proved by the owner or owners representative to do inspec-tions.2.1.4 catalystsubstance which markedly speeds up thecure of an adhesive when added in small quantities ascompared to the amounts of primary reactants.2.1.5 chemical groutinjection repair media other thancementitious grout that may be multi-component,with orwithout additives,and based on either polyurethane resin oracrylic resin.2.1.6 control agentsubstance added which controls theviscosity or flow properties of the material it is added to.2.1.7 engineeran engineer registered in the state wherethe work is to be done who has been contracted by or is actingon behalf of the owner or the owners representative.2.1.8 exfiltrationleaking or weeping to the external areasoutside the barrier from a source inside the barrier.2.1.9 expanded gasket procedure(EGP)the sealing ofjoints,cracks,or holes by soaking dry,oil-free oakum withchemical grout and forcing the oakum/resin plug into theopening until it sets.2.1.10 hydrophilic grouthydrophilic grout will absorb andreact with the water it comes into contact with.2.1.11 hydrophobic grouthydrophobic grout will repelwater and push it away.2.1.12 manholevertical shafts that intersect with sewers toallow transitions in alignment and grade and to allow entry forcleaning,inspection,and maintenance.2.1.13 oakumloose hemp or jute fiber,sometimes treatedwith resin or grout,used chiefly for caulking seams instructures and boats as well as packing pipe joints.2.1.14 owners representativethe individual who has beencontracted to act on behalf of the owner for project planningand supervision.2.1.15 polyurethane resinany of various polymer resinscontaining the urethane radical;a wide variety of syntheticforms are made and used as adhesives,plastics,foams,paints,or rubber-like materials.1This practice is under the jurisdiction of ASTM Committee F36 on Technologyand Underground Utilitiesand is the direct responsibility of Subcommittee F36.20on Inspection and Renewal of Water and Wastewater Infrastructure.Current edition approved May 1,2009.Published June 2009.Originallyapproved in 2004.Last previous edition approved in 2004 as F2414 04.DOI:10.1520/F2414-04R09.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.1.16 RCPreinforced concrete pipe.2.1.17 rehabilitated manholea manhole restored to itsintended capacity or use per the specifications.2.1.18 repaired or sealed manholea manhole that hasbeen sealed from detected infiltration or exfiltrations,but notnecessarily restored to its original designed capacity.2.1.
