Layne Inliner® has successfully installed over 16 million feet of CIPP throughout the United States in diameters ranging from 4-inch up to 90-inch. This trenchless rehabilitation process allows for the no-dig renovation of existing pipelines and can add a service life of over 50 years to the buried pipeline.


We began as the first U.S. licensee of the Inliner® technology in the early 1990's and have grown to a position of national prominence since that time. As owners of both the technology company – INLINER TECHNOLOGIES – and the liner manufacturer – LINER PRODUCTS – we have unique control over the QA/QC of raw material purchasing, design, manufacturing and ultimate product installation. We are committed to research and development, have years of experience with innovative forms of project delivery, and maintain the highest degree of safety management in our industry. While we have several solutions to choose from, the Cured-in-Place pipe process (CIPP) is our most sought-after solution. It is a cost effective alternative to traditional dig and replace, and eliminates or greatly minimizes the inconveniences associated with roadway and private property open cut digs.


After cleaning and televising the existing pipeline, a liner tube is ordered that will later be installed via manhole or other access point into the damaged or leaking pipe. The liner is designed to become a fully structural pipe within a pipe or can serve as an infiltration barrier only – this determination and existing load conditions govern the final thickness of the CIPP tube. Once delivered to the jobsite, the resin impregnated tube is installed either by direct inversion (ASTM F1216) or pulled in place (ASTM F1743). An application of heat begins to cure this liner after it is in place within the host pipe and this heat source can be steam, hot water or ultraviolet light. Following the cure and subsequent cool down, customer laterals if present are reinstated from the inside using robotic cutters and the pipeline is placed back into active service.
