Robotic Rebar Removal Avoids Excavating Clay Drain Morning cleaning information

Bespoke robotic cutting tool removes two re-bars

Two re-bars had been inadvertently forced through a clay sewerage pipe during the construction of a new lecture hall at Nottingham University. Construction contractors needed re-bars removing and the pipe made serviceable as quickly as possible in order to avoid costly excavation, replacement and building delays.


  • While reinforcing a wall, 2 re-bars were drive3n into a clay sewerage pipe on site.
  • The first rebar went completely through the pipe, the second only 2 inches in.
  • With tight deadlines, the re-bars needed removing and pipe repaired quickly.


  • Tube Tech were contacted via the web and given the challenge
  • Access points and distances were quickly established
  • Bespoke robotic cutting tools were able to remove both re-bars located 1m and 6m from the nearest manhole.
  • The pipe was immediately lined to leave a pipe ready to be put into service.
  • The contract was completed to the clients’ satisfaction within hours of arrival.
