ASTM F2454-05 (R2016)e1 PDF Download

ASTM F2454-05 (R2016)e1 is a standard practice that outlines the procedures for testing and sealing sewer lateral connections and lines from the mainline sewer using chemical grouting with the lateral packer method. The purpose of this standard is to reduce infiltration and exfiltration in sanitary sewer systems, while minimizing disruption to traffic and environmental impacts.

The practice involves the use of television or optical inspection to assess the condition of the sewer lateral connections and document any necessary repairs. Chemical grouting is then used to seal the connections and a predetermined portion of the lateral lines. It is important to note that this practice should not be used in cases where the mainline or lateral connections exhibit cracked, structurally unsound, flattened, or out of round pipes.

The standard applies to mainline sewer diameters ranging from 6 to 24 inches, with 4, 5, or 6-inch diameter laterals. For larger diameter pipes with lateral connections, special packers or man-entry methods may be required. It is essential that both the mainline and lateral pipes are structurally adequate to effectively create a seal.

Worker safety is a crucial consideration in this practice, and proper training should be provided on biohazard and gas exposure from sewage, confined spaces, pumping equipment, and related apparatus. The chemical grout manufacturer or supplier should also provide guidance on the safe handling, mixing, and transportation of the grouts and associated containers, as well as the appropriate personal protective equipment for various grouting operations.
