Granite Inliner is a leading provider of trenchless water and wastewater system renewal services
From our flagship Inliner® Cured-In-Place Pipe (CIPP) to our glass-reinforced Inliner STX® UV-cured liners and technologies, we rehabilitate a broad range gravity and pressure pipeline systems. Our approach reduces disruption to the public and the environment, while completing the project in less time and less cost than traditional excavation.
Granite Inliner teams have successfully installed more than 35 million feet of CIPP throughout the United States and Canada. Performing in various geographic and climatic conditions, our teams have rehabilitated both circular and non-circular piping structures ranging from 4” to 120” in diameter.
Inliner STX is manufactured in the United States and incorporates a fiberglass reinforced tube that provides a higher-strength and thinner wall designs. This design maximizes hydraulic capacity and reduces resin consumption – significant benefits as the diameter increases.
In addition to our flagship Inliner® CIPP product for gravity wastewater applications, Granite Inliner also offers pressure pipe rehabilitation and potable water main rehabilitation solutions.
Granite Inliner’s lateral lining service, developed by LiquiForce, is a key process of our trenchless technology portfolio. Our process includes cleaning the existing lateral, electronically measuring it for a new custom liner and installing the new lateral liner from the mainline sewer. All work is completed without access to a property line clean-out or within the home.
Granite Inliner performs manhole renewal installations that meet each client's specifications, using both Cured-In-Place Manhole (CIPMH) and a variety of cementitious, epoxy-based applications. Granite Inliner also provides extensive manhole inspections.
Our geopolymer lining is a trenchless rehabilitation method applied by using monolithic mineral polymer with ceramic properties to repair existing pipelines. These applications will adhere to any structure surface, and unlike traditional cement- based mortars, they are also capable of bonding and building to great thicknesses.
Liner Products is a Granite-owned liner manufacturing operation that provides reliable and high-performance CIPP products to installers throughout the U.S. These products include tubes for inversion and pull-in-place methods for mainline CIPP, calibration hoses, lateral liners, as well as pre-liners.
Inliner Technologies is a known, trusted resource within Granite Inliner and serves as the research and development group, providing innovation to the marketplace and supporting current product applications with design recommendations, feasibility and field process controls.
LiquiForce joined Granite Inliner in 2018, and is a leader in no-dig pipeline rehabilitation for clean water, wastewater and other pipeline systems. Our sustainable pipeline rehabilitation systems provide new pipe standards and durability, and significantly reduces pipeline repair time with minimal disruption. LiquiForce is pipeline service provider offering complete pipeline system inspection, assessment, rehabilitation and maintenance. Granite acquired LiquiForce in 2018, and currently maintains Canadian operations, serving all provinces, as well as U.S. operations.
Granite Inliner's Combined Strength Through Acquisition
