Annular Space Grouting - 2010
While liners, when properly designed and constructed, will stabilize the structural integrity of the host pipe, even close-fit liners will not eliminate the problem of infiltration. The use of injection grout will seal both the annular space between the host pipe and liner and any leaks at the later...
