Problem Identification
Sewer lining saved the day for a local elementary school that was experiencing repeated sewer backups. The elementary school, located in Monee, Illinois, began experiencing frequent sewer backups so they called Trenchless Innovations to investigate. The six-inch cast iron main sewer line running under the main hallway and connecting all bathroom lines, was the culprit. School administration was desperate for a solution that wouldn’t cause heavy disruption and inconvenience to faculty and students. That’s where sewer lining from Trenchless Innovations comes in!
Video Inspection and Descaling
A video inspection of the line showed that heavy scale was causing the repeated backups. Descaling the pipes was recommended and performed by Trenchless Innovations’ sister company, Reid & Pederson Drainage. Although descaling helped, another video inspection uncovered pipes in such fragile condition that further cleaning or descaling would be disastrous. In fact, one area of the pipe was so fragile that the top of it fell in, allowing backfilled stone around the pipe to enter. Trenchless Innovations came up with an alternative plan that would solve the problem but not make a mess in the process.
Lining the Sewer
Using powerful commercial vacuums and high-pressure water jetting, our team cleared the stone from the pipe. Installing a patch liner and covering the area where the hole was located, prevented stone from further entering the pipe. With that completed, our team was ready to line the remainder of the compromised pipe.
Our team lined approximately 90 feet of pipe, beginning as a 4-inch pipe that transitioned to 6-inch pipe. Using a special liner that accommodated for this change in diameter, it allowed the entire pipe to be lined in one shot. Our team successfully installed the custom liner in the sewer pipe and cured the resins using steam. All that remained was a solid, cured in place liner with two reinstated lateral connections – and a school that was back in service without any digging or disruption to surroundings, faculty or students.
