The Job
This Georgia pipe abandonment project by CJGeo is located on Old Alabama Rd, in Roswell. It involved installing a new water main that was routed away from GA-19 into a more accessible location. After the new pipe was installed, 5280LF of 48" water main needed to be completely filled.
Generating and placing the CJFill-UL cellular grout.
The Challenge
Cost, speed, and minimizing the number of access points were the most important factors on this project. Access was tricky, due to the adjacent highway, residential areas, and the Chattahoochee River National Recreation Area.
The Solution
Venting water from the pipe.
CJGeo proposed 30lb/cuft CJFill-Ultra Lightweight cellular grout to the general contractor. The relatively few placement points required, along with the cost, were both very attractive alternatives to flowable fill.
CJGeo mobilized a single dry batch cellular grout plant. Over a period of 7 days onsite, CJGeo generated and pumped 2,328 cubic yards of cellular grout. The large cement pig shown in the photo above was used to address traffic disruptions in the daily supply of dry bulk cement.
