ASTM F2551-09 (R2016) is a standard practice that outlines the procedures for installing a protective cementitious liner system in sanitary sewer manholes. The purpose of this standard is to provide guidelines for structural reinforcement, sealing, protection, and rehabilitation of manholes using a prepackaged cementitious liner system.

The standard covers manholes made of various materials including brick, concrete, and block, and provides detailed descriptions for all the materials needed for the installation process. This includes substrate repair materials, cementitious repair materials, infiltration water control materials, cementitious water control materials, chemical grout materials, and lining materials.

The practice outlines various procedures involved in the installation process, such as surface preparation, high-pressure cleaning, surface repair, mixing of prepackaged cementitious repair materials, spray application of the cement liner using either manual surface sealing or centrifugal cast process, and curing of the freshly applied cementitious mortar.

The standard emphasizes the importance of following the manufacturer's recommendations for all cleaning, preparation, and application procedures. It also mentions that a manufacturer's approved applicator should be responsible for the complete application of the protective cementitious liner material.
