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 20 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.
