Sectional Mainline Repair

LMK’s Performance Liner® Sectional System meets the design calculations found in ASTM F1216, Appendix XI and the standard practice of ASTM F2599, the Sectional Repair of Damaged Pipe by Means of an Inverted Cured-in-Place Liner. It is a unique, one-step, air-inversion spot repair process that prevents resin contamination and loss, which are key to a successful CIPP installation. This system renews mainlines from six to 42 inches in diameter and from three to 100 feet in length. When installed with Insignia O-Rings at the terminating ends, the Sectional Spot Repair offers a watertight as well as structural repair.


LMK Technologies has pioneered CIPP lateral renewal technology and has driven the industry forward with new products and technologies to facilitate sewer rehabilitation of sewers for 20 years. In its relatively small lifespan as a company, LMK has invested time and resources in research and development
