The lateral grouting plugs are installed on the lateral packers to test & seal the lateral connection & joints of the lateral line from the mainline sewer. The grout migrates along the restricted expansion of the lateral plug and seals defects, leaving only a tiny layer of grout in the lateral. The lateral grouting plugs can be changed on the site in a few minutes.
Lateral grouting plugs come in different lengths in one foot increments starting at 2 feet up to 30 feet, for 4″, 5″ or 6″ diameter laterals.
Flexible Housing Extensions are necessary for most lateral grouting plugs. These extensions provide a storage area for the inversion and retraction of the lateral grouting plug within the mainline packer. The minimum length of the Flexible Housing Extension is determined by the length of the lateral grouting plug.

|Product #||Deflated Length* (DL)||For Service Lateral Size||Approx. Grouting Distance in Lateral (GD)|
* Longer Lateral Grouting Plugs are available up to 30 feet.
To choose the proper lateral grouting plug, use these formulas:
4″ diameter lateral: DL = GD desired x 1.15 + 14″
5″ diameter lateral: DL = GD desired x 1.20 + 14″
6″ diameter lateral: DL = GD desired x 1.23 + 14″
The use of a 3-6 A Logiball pneumatic plug facilitates the strapping of the lateral plug onto the screw type adaptor.
