Testing Manhole Linings Can Be Dirty Work

As part of the G-100 Sewer Repair project in Washington D.C., several manholes were lined with cementitious materials to prevent inflow and infiltration which was costing millions of dollars a year in extra water treatment. As part of this repair process, Balter tested the cement lining for it's adhesion strength as well as the pullout resistance of newly placed steps. This, along with laboratory testing of Cured In-Place Pipe (CIPP) and video inspection of storm and wastewater sewer lines, is part of Balter's expanding role in the testing and inspection of city sewer infrastructure projects.
