Sewer Penetration Sealing

Sewer wall penetration sealing, Williamsburg, Virginia

Polyurethane foam jacking to seal sewer pipe penetration through wall.

Sealing sewer pipe penetration with polyurethane.


Water was leaking through the wall of a residential home around the sanitary sewer’s wall penetration.  Previous repairs by the builder included caulking the joint between the wall & pipe multiple times.  This was never successful at completely stopping the water intrusion.


High density polyurethane injection to seal the pipe penetration.


Concrete Jack foam jacking crew successfully sealed around the pipe.  Some water was squeezed out of the joint between the pipe and wall, and foam came to the surface on the outside.
