Cellular concrete is an excellent choice for pipe abandonment projects. Because lightweight cellular concrete is a single component material, there is no risk of segregation, so the entire volume of an abandoned structure is completely uniform in fill. Concrete Jack performs pipe abandonment using lightweight cellular concrete in Virginia, Maryland, North Carolina, West Virginia and Pennsylvania. Cellular concrete can be installed at very low pump pressures due to its superior flowability and light weight. Thus, it is an excellent choice for annular space grouting around liner pipes installed as part of slip lining.
