  • Method for repairing sewer pipes
    Patent number: 4170248
    Abstract: A sewer pipe is repaired by inserting a thin, flexible liner within the sewer pipe. The liner has an outer diameter less than the inner diameter of the sewer pipe, whereby an annular space is presented between the liner and the sewer pipe. This annular space is filled with a low viscosity magnesium based cement, such as magnesium oxychloride cement or magnesium oxysulfate cement, which has a maximum Marsh funnel viscosity of 40 seconds per quart.
