M. Tucker and Sons install junction seals and top hats to repair lateral connections within sewer and stormwater pipes. The process involves using a robotic packer system, which positions a resin-impregnated fiberglass liner at the junction between the main pipe and the lateral connection. The packer inflates, pressing the liner against the pipe walls, sealing any leaks or defects. Once cured, the resin forms a watertight, durable seal, preventing infiltration and root intrusion. This trenchless method is quick and minimally invasive, ideal for maintaining the integrity of underground infrastructure without extensive digging.
