Designation:F255109(Reapproved 2016)Standard Practice forInstalling a Protective Cementitious Liner System inSanitary Sewer Manholes1This standard is issued under the fixed designation F2551;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.INTRODUCTIONAsanitary sewer manhole may be repaired or rehabilitated by applying a prepackaged cementitiousliner to the interior surface after it has been properly prepared and cleaned.Sanitary sewer manholescan be damaged by dynamic loading,abrasion,erosion,and corrosion.1.Scope1.1 This specification describes all the work required tostructurally reinforce,seal,and protect sanitary sewer man-holes.Applications include applying a prepackaged cementi-tious liner that can function as a full depth restoration or apartial depth repair.A uniform high-strength,fiber-reinforcedcementitious mortar should be manually sprayed and handtroweled or centrifugally cast in a uniform,prescribed thick-ness to all cleaned,interior surfaces from the bottom of theframe to the bench.The cementitious liner may be applied tomanholes constructed of brick,concrete,block,and variousother materials.1.2 A manufacturers approved applicator shall furnish thecomplete application of the protective,prepackaged cementi-tious liner material.All of the cleaning,preparation,andapplication procedures shall be in accordance with the manu-facturers recommendations.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 and health practices and determine the applica-bility of regulatory limitations prior to use.Manholes arepermit required confined spaces in accordance with OSHAdefinition and should be treated as such,requiring confinedspace entry permits,appropriate monitoring equipment,andthe associated personal protective equipment.2.Referenced Documents2.1 ASTM Standards:2C39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm CubeSpecimens)C309 Specification for Liquid Membrane-Forming Com-pounds for Curing ConcreteC494/C494M Specification for Chemical Admixtures forConcreteC969 Practice for Infiltration and Exfiltration AcceptanceTesting of Installed Precast Concrete Pipe Sewer LinesC1140/C1140M Practice for Preparing and Testing Speci-mens from Shotcrete Test PanelsC1244 Test Method for Concrete Sewer Manholes by theNegative Air Pressure(Vacuum)Test Prior to BackfillC1315 Specification for Liquid Membrane-Forming Com-pounds Having Special Properties for Curing and SealingConcreteF2414 Practice for Sealing Sewer Manholes Using ChemicalGrouting2.2 ACI Standards:3ACI 301-05 Specifications for Structural ConcreteACI 305R-99 Hot Weather ConcretingACI 306R-88 Cold Weather ConcretingACI 308R Practice for Curing Concrete1This practice is under the jurisdiction of ASTM Committee F36 on Technologyand Underground Utilities and is the direct responsibility of Subcommittee F36.20on Inspection and Renewal of Water and Wastewater Infrastructure.Current edition approved April 1,2016.Published May 2016.Originallyapproved in 2009.Last previous edition approved in 2009 as F2551-09.DOI:10.1520/F2551-09R16.2For 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),38800 Country Club Dr.,Farmington Hills,MI 48331-3439,http:/www.concrete.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 ACI 506R Guide to Shotcrete2.3 ICRI Technical Guidelines:4Guideline No.03732 Selecting and Specifying ConcreteSurface Preparation for Sealers,Coatings,and PolymerOverlaysGuideline No.03737 Guide for the Preparation of ConcreteSurfaces for Repair Using Hydro-demolition Methods3.Ordering Information3.1 SubmittalsOrders for all prepackaged materials listedunder this practice shall include the following:3.1.1 Product data,including manufacturer and brand name;3.1.2 Technical data stipulating physical characteristics ofapplied liner material;and3.1.3 Manufacturers Safety Data Sheets.3.2 Delivery,Storage,and Handling:3.2.1 The prepackaged cementitious materials should bestored according to the manufacturers recommendations.Nomodification should be made to the manufacturers r
