The Job
This North Carolina annular grouting project is located in Havelock, North Carolina. Havelock is home to Marine Corps Air Station Cherry Point. US 70 passes through Havelock, providing a critical link between New Bern and the coastal beaches of North Carolina.
The Challenge
As part of North Carolina DOT work to upgrade the capacity and increase safety of US 70, a number of wet utilities were upgraded and relocated. This required a number of jack and bore crossings of the existing roadway to avoid disrupting traffic. NCDOT requires annular grouting for jack and bore crossings of wet utilities, for anything with less than a 100 year design life.
The Solution
This project had two crossings needing annular space grouting. One was 120 linear feet of 42″ steel casing with an 18″ ductile iron pipe water line. The second was 86 linear feet of 42″ steel casing with an 18″ ductile iron water line.
A CJGeo cellular grouting crew successfully filled each of the two casings with CJFill-Ultra Lightweight cellular concrete in a few hours in a single day. Carrier pipe buoyancy was not a concern due the low density of the grout.
