PGELarge natural gas providers such as Pacific Gas and Electric, have miles of high pressure gas pipelines to maintain. Often pipelines run across private property and access is limited. For this project we utilized the highly pumpable nature of cellular concrete to save the contractor significant money by filling a 4,400 LF run of 16″ abandoned gas main in a single push. This eliminated the need for excavating Pumping pressures never exceeded 15 psi.
