Thinking outside the Box ! In June of 2004 Logiball received a call from the Village of Brown Deer, WI.. Mr. Nietzel wanted to know if laterals could be sealed, using chemical grout, from the mainline sewer up 30 feet from the connection. There were no cleanouts on these lines and all the work had to be performed from the mainline sewer. At that time, the longest that had been done was 20 feet. Logiball decided to build the Lateral Packer and tested it successfully above ground. The packer could be built and proved to be effective in an above ground setup, but we all know that field conditions and above ground conditions are two different animals. Logiball insisted that all the laterals to be tested & sealed had to have a pre-cctv inspection on at least 40 feet from the connection with a satellite camera from the mainline. Also any obstructions or pipe conditions that would prevent the full inversion of the lateral bladder be corrected prior to attempt using the lateral packer. Great Lakes TV Seal Inc. (Green Bay based) used the LETS system from Aries industries to inspect the laterals from the 8” mainline sewer up to 45 feet from the connection. Indeed there were roots, grease & mineral deposits that had to be removed.		Logiball Lateral Launcher to clean 45 feet of the lateral from the mainline. Post CCTV inspections confirmed that the cleaning of the laterals proved to be very effective, roots, pieces of clay tile and other build-ups were removed restoring the lateral pipes capacity. An above ground pipe assembly was installed at Great Lakes TV Seal facilities where the final preparations were done with the Aries rig (confirming the inversion and vacuum of the lateral bladder, volume of the void, adjusting pumping rate, grout gel time, etc). The next step was to insert the 42 foot long assembly into the mainline sewer. Once positioned over the lateral, the lateral bladder was pressurized and inverted 38 feet up the lateral (all laterals were at least 45 feet long). With the mainline bladders inflated 30 feet of the lateral was isolated. The grout pumps were turned on (approx 6 gpm) for two minutes and then slowed down to 3 gpm with gel times (acrylamide grout) varying from 2 to 3 minutes until a satisfactory void pressure was obtained. In some cases it was decided to stage the grout until the 6 psi void pressure was reached and held. Laterals sealed required anywhere from 18 up to 75 gals. The laterals were then air tested at 5 psi. In most cases a flush from the occupants was obtained confirming the flow was not obstructed. The sections where the two dozen laterals cleaned and sealed 30 feet from the mainline will be closely monitored for infiltration reduction. Congratulations to & Great Lakes TV Seal for a job well done !
