This practice describes the procedures involved in the structural reinforcement, sealing, protection, and rehabilitation of sanitary sewer manholes by the application of a prepackaged protective cementitious liner system to all cleaned interior surface from the bottom of the frame to the bench. The manholes to which the cementitious liner shall be applied may be made of brick, concrete, block, and various other materials. Detailed descriptions are given for all prepackaged materials necessary for this practice that include materials for substrate repairs, cementitious repair materials, infiltration water control materials, cementitious water control materials, chemical grout materials, and lining materials. Detailed descriptions are also provided for each procedure involved here which includes surface preparation, high pressure cleaning, surface repair, mixing of prepackaged cementitious repair materials, spray application of the cement liner by manual surface sealing or centrifugal cast process, and curing of the freshly applied cementitious mortar.
1.1 This practice covers the procedures to repair, reinforce, seal, and protect storm or sanitary sewer manholes and structures by the installation of a prepackaged cementitious (typically portland or calcium aluminate) or geopolymer-based mortar that can function as a full depth restoration or a partial depth repair. A high-strength, fiber-reinforced cementitious or geopolymer mortar is manually sprayed, hand troweled, or centrifugally cast in a uniform, prescribed thickness to all cleaned, interior surfaces from the bottom of the frame to and including the bench and channel. The cementitious or geopolymer liner may be applied to manholes and structures constructed of brick, concrete, block, corrugated metal, and various other materials.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Manholes are permit-required confined spaces in accordance with OSHA definition and should be treated as such, requiring confined space entry permits, appropriate monitoring equipment, and the associated personal protective equipment.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
