Sealing Annular Space

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...
Annular Space Grouting - 2014
Chemical grout travels freely between the liner and host pipe to cure in place and eliminate infiltration.
Seal "Lined" Lateral Connection
Sealing a service line 21-ft. from a mainline sewer that has been lined with CIPP. Note: Grouting the lateral/mainline connection will seal the service line as well as stop water flow.
Grouting and Lining Work Well Together
This video shows how grouting and lining work together to prevent Inflow & Infiltration (I&I).
