More work is being performed on lateral connections than ever before, whether it be grouting or lining. In some cases, lateral connection lining requires stopping the infiltration prior to performing the lining work. Chemical grouting is easy with the lateral connection sealing kit which includes a push grout packer and a special flow-thru plug.
With an above ground access and standard manhole, it is possible to position a special flow thru plug that will straddle the connection and insert a special push grout packer from the cleanout. By inflating the plug and packer, the connection is isolated from the rest of the system. Chemical grout can be pumped and the service connection sealed from infiltration.
