ASTM Committee Votes to Renew ASTM F2561 for another Five Years

Ottawa, IL (June 1, 2016) – In April, the ASTM International committee F17 , Plastic Piping Systems and subcommittee F17.67, Trenchless Plastic Pipeline Technology, voted to renew the ASTM F2561 standard of practice an additional five years. ASTM F2561 was first published in 2006, first renewed in 2011 and now again in 2016.

ASTM F2561-16 is the standard practice for rehabilitation of a sewer service lateral and its connection to the main using a one piece main and lateral cured in place liner. The practice covers the requirements and test methods for the reconstruction without excavation. The lateral pipe is accessed remotely from the main pipe and from a lateral cleanout, if available. A resin impregnated one-piece main and lateral CIPP lining is installed by the use of air and inversion. The CIPP liner is pressed against the host pipe by pressurizing a bladder and is held in place until the thermoset resin has cured. The result is a verifiable non-leaking structural continuous, one piece, tight fitting, corrosion resistant connection lining and seal that extends over an 18″ section of the mainline and into the lateral for a predetermined length.

LMK Technologies is one of two industry companies that provide a lining system that fully meets the ASTM F2561 standard of practice. The patented, T-Liner® Main-to-Lateral Connection System, has been installed in over 50,000 service laterals by a growing network of independent distributor-contractors based throughout the United States, Canada and Europe.

T-Liner® incorporates the use of Insignia® hydrophilic swelling gasket seals at the connection and the lateral termination. When exposed to water, the gaskets swell in 36 to 48 hours providing a verifiably sealed system, preventing water from re-entering the collection system. Other lining systems try to use the thermoset resin as the watertight solution. The ASTM F2561 ensures a water-tight solution that equals the 50 plus year design life.

“To have a prestigious body of industry experts continue to renew the ASTM F2561 standard since 2006 indicates that the T-Liner lining system provides the highest degree of quality and long term results,” according to LMK Vice- President of Sales, Rick Gage. “We continue to educate the marketplace about the need to utilize ASTM standards when developing any construction or rehabilitation project. Using an ASTM standard ensures that the rate payers and owners are getting full value for their money.”

ASTM (American Society for Testing and Materials) was established in 1898 and today has more than 12,000 ASTM standards and a membership of over 30,000 of the world’s top technical experts and business professionals representing 140 countries. Working in an open and transparent process and using ASTM’s advanced IT infrastructure, the members create the test methods, specifications, classifications, guides and practices that support industries and governments worldwide.

LMK Technologies, a world leader specializing in trenchless methods to renew lateral sewer infrastructure has more than 100 worldwide issued patents for its advancements in trenchless technology. Headquartered in Ottawa, IL since 1993, LMK serves the municipal and residential markets through a network of licensed and certified contractors. For more information regarding LMK please visit,
