What LMK Technologies, LLC does

LMK Technologies, LLC is an Ottawa, Illinois-based manufacturer of cured-in-place pipe (CIPP) lining systems and equipment for trenchless sewer rehabilitation, founded in 1993 by Larry Kiest Jr. The company's core technology is one-piece main-and-lateral CIPP connection lining paired with its proprietary Insignia hydrophilic gasket sealing system, which is engineered to prevent water migration behind liners — the dominant failure mode in CIPP rehabilitation. The product portfolio centers on the T-Liner family (Original T-Liner, Shorty, Stubby), the Performance Liner Lateral and Sectional systems, the VAC-A-TEE cleanout installation system, the Lapel Liner for large-diameter mains (27-60 inches), and the LightRay LRS UV-curing system, plus accessories such as the Lined Main Tap (LMT) Saddle. The company holds more than 100 U.S. and foreign issued patents and has driven the development of multiple ASTM standards (F2561, F3240, F3097, F2599, F1216), making it the reference implementation for engineers who specify main-to-lateral CIPP work.

LMK generates revenue through four primary streams: (1) sale of proprietary CIPP liner consumables and Insignia gasket products, (2) sale of custom trenchless installation equipment (wet-out trailers, steam trucks, launch tanks) and complete turn-key system packages, (3) per-state license fees and mandatory 4-day training programs charged to authorized independent contractors, and (4) direct sales to utility owners and municipalities, including licensing of patented technologies for self-installation and equipment resale for Picote and Schwalm robotics as the North American distributor. The company serves four primary customer segments — utility owners/municipalities, specifying engineers, trenchless rehabilitation contractors, and plumbers/drain cleaners — and has been recognized with a Chicago Innovation Award (2015), WEF Citation of Excellence awards, and an NASTT Ralston Award (2017). Since April 2019, LMK has operated as a subsidiary of Waterline Renewal Technologies, a platform consolidator in trenchless infrastructure rehabilitation that also owns PLI/Perma-Liner.
