After various failed attempts of different nozzles and cutters, Sewer Robotics was invited to remove the concrete that has been blocking this 400mm sewer main line for the past 10 years.
Years of mineral deposits leaving a layer of calcite and narrow joints inside this 200mm (8”) clay sewer main pipeline. Water jet cutting applies a high pressure low volume water blast from a special designed crawler with camera and pan…
Scaling and tuberculation reduced the flow in cast iron pipelines. The pipe flow was restored with a water jet applied from a robot with camera and rotary nozzle with 500bar (7,250psi) water pressure.
The R125 crawler with WJ125 water jet module, was used to remove the root infiltrations that this failed liner could not prevent from infiltrating this 6 inch (150mm) sewer mainline.
Removing a few thick tree roots that grew into a 200mm (8") VCP sewer pipe from the joint. 500bar (7,250psi) was used in combination with a rotary nozzle on the water jet cutting robot to remove the root infiltration in…
