Since 1999 PLI has developed systems to rehabilitate existing sewer systems without excavation.
HOW'S IT DONE?
TELEVISE THE PIPELINE. Pipeline is inspected with camera to find problem.
CLEAN THE PIPELINE. Pipeline must then be cleaned out to remove roots, dirt, debris and any potential objects that could disrupt lining.
TAKE MEASUREMENTS. Measurements of the pipelines diameter, depth and length are taken. The liner and calibration tube is then cut on the job site according to acquired measurements.
MIX & MEASURE RESIN. Resin is also measured and mixed according to the acquired measurements
POUR INTO LINER. The resin is then poured into the liner and rolled or “wet out" many times to ensure complete impregnation of resin to liner.
LOAD INTO INVERTER. Impregnated liner and calibration tube is then loaded into the inverter.
INSERT INTO EXISTING PIPELINE. The liner is then inserted into the existing pipe using directional hoses and inversion heads. These ensure proper insertion.
INVERT WITH AIR PRESSURE. Air pressure then inverts inside out allowing resin to bond and seal with existing host pipe. The calibration tube acts as a balloon to keep the liner in place as it cures.
READY FOR SERVICE. Once cured, the calibration tube is removed and the pipe is ready for service.
