ASTM F2454-05 (R2022) PDF Download

ASTM F2454-05 (R2022) is a standard practice that guides the testing and sealing of sewer lateral connections and lines from the mainline sewer using the lateral packer method and chemical grouting. The purpose of this practice is to prevent groundwater infiltration and sewage exfiltration in structurally sound gravity flow sewer systems.

This standard applies to mainline sewer diameters ranging from 6 inches to 24 inches, with lateral connections of 4 inches, 5 inches, or 6 inches in diameter. For larger diameter pipes, special packers or man-entry methods may be required. It is essential that both the mainline and lateral pipes are structurally adequate to ensure an effective seal.

Worker safety is emphasized in this practice, as proper training is necessary to address potential biohazards, gases from sewage, confined spaces, and the use of pumping equipment and related apparatus. The chemical grout manufacturer or supplier should provide additional safety considerations, such as handling, mixing, and transporting of chemical grouts. Detailed instructions on personal protective equipment (PPE) relevant to different grouting operations should be provided. Storage, transportation, mixing, and disposal procedures for chemical grouts and additives are also covered.
