Lower Northwest Interceptor Sacramento, CA
Annular Space Grouting
This project consisted of a 19-mile sewage conveyance pipeline and pump station system that required micro-tunneling methods to install the new lines anywhere pipe could not be installed in an open-cut trench, such as under the Sacramento River or I-80.
The micro-tunneling operation was completed by filling the annular space around the pipe with Geofill LD cellular concrete to prevent corrosion and movement. This flowable material also reduced potential flotation or collapse of the carrier pipe.
