Sewer Overflows

Annular Space Grouting - 2014
Chemical grout travels freely between the liner and host pipe to cure in place and eliminate infiltration.
Leaking Lateral Connection Sealed
View footage of leaking lateral connection before and after it is sealed with chemical grout.
Probe Grouting
View how probe grouting makes a positive seal on the perimeter surface of the manhole to eliminate infiltration.
Manhole: Vertical Crack Injection
View Avanti chemical grout being injected to stop vertical leaks within the manhole wall to stop infiltration.
Manhole: Horizontal Crack Injection
View Avanti chemical grout being injected to stop horizontal leaks within the manhole wall to stop infiltration.
Sewer Grouting: Mainline Sewer
View how to seal a mainline joint between two manholes.
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.
Stop Infiltration in Subways and Tunnels
View animation of curtain grouting to stop water infiltration in subways and tunnels.
Grouting Overview
Municipalities treat 50% groundwater which can be eliminated by sealing mains, manholes, and laterals.
Grouting and Lining Work Well Together
This video shows how grouting and lining work together to prevent Inflow & Infiltration (I&I).
Curtain Grouting
Curtain grouting technique is proven to stop groundwater infiltration.
Lateral Leaks in Lined Pipe Sealed
