SEWER RENOVATION WITHOUT SURFACE DISRUPTION

The author describes the in situ form method of renovating underground pipework. A tube or bag to fit exactly to the internal dimensions of the pipe to be lined is manufactured from a polyester needled felt. The felt tube is impregnated with a resin mixed with a catalyst. The mouth of the bag is clamped over an inversion ring, the lining is filled with water and turned inside out into the sewer, depositing a layer of felt and resin on the inner wall of the pipe. The water is circulated through a boiler and maintained at a temperature of 70-80 degrees C to cure the resin. Pipes with diameters in the range 100 mm to 1200 mm can be renovated by means of the process, lengths of over 300 m having been done in one inversion. The method of dealing with incoming lateral pipes and methods of cutting the tube are outlined. (TRRL)
