Michigan Pipe Abandonment

Michigan Water Main Abandonment

Saginaw, Michigan

The Job

This Michigan water main abandonment project is located in Saginaw, Michigan. It is a 2900LF of 8″ grouted abandonment for the local municipality.

The Challenge

The utility contractor who installed the replacement water main was required to fill the old pipe with grout after tying in the new pipe. Because of the relatively small diameter, they were going to have to dig approximately 15 access holes if they used traditional flowable fill. The contractor really didn’t want to have to do that. So, they sought a highly mobile grout that would eliminate the need for digging access points.

The Solution

CJGeo proposed using CJFill-Ultra Lightweight cellular grout for this Michigan water main abandonment. Because the project volume is approximately 40 cubic yards. CJGeo proposed using wet batch generation, with a local ready mix provider supplying the raw slurry.

Wet batch generation is well suited for projects like this because the volume of slurry required is much less than a full load of cement. The equipment for wet batch generation is very portable–typically just two pickup trucks, one pulling a 20′ trailer with equipment.

Confirmation of fill for this Michigan water main abandonment project was material venting a fire hydrant at the far end of the placement. Pumping pressures were less than 20psi for the duration of the grouting process.
