Mainline Cured-in-Place Pipe

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. 

Structures

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. 

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.

Pressure Pipe Technology

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. 

 

 

Lateral Cured-in-Place Pipe

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.
