5 Reasons Why Corrective Action is Needed When Pipe Bursting

There are times when a pipe bursting operation fails. Many factors can affect the success of this trenchless pipe replacement method. It could be from a human or machine error during the procedure. Soil conditions can also affect the whole operation. A failed pipe bursting doesn’t mean there can’t be anything done. Experienced contractors know the ins and outs of pipe bursting. They will be able to take corrective action to successfully install the new pipeline. There are many reasons why corrective action may is required such as:

  1. The bursting pressure used was too much

Bursting pressure is applied to old pipes in order to break them; however, there are times when there is excessive use of force. The bursting head might move forward to continue and break other sections. Miscalculation is a common reason but there are other causes as well. This includes alternating soil conditions, equipment failure, etc.

  1. Crumbled and collapsed pipe line

This is a big issue when it comes to replacing pipes since it causes the project to extend. The purpose of pipe bursting is to break the old pipes not the entire pipeline. A collapsed pipeline would require the repair team to excavate it. Collapsed pipes will stop the bursting head from pushing forward to other sections. This will also make it impossible for the new pipes to be pulled into position. Evaluation of the pipe is done before the bursting method to check if pipes have collapsed or not. There may be instances in which a pipeline will break before or during the pipe bursting method. The collapsed pipe line must be removed to proceed with the operation.  

  1. The pipe that needs to be replaced is different in the original plan

It’s important that the contractor knows what the materials the old pipe is made of. You see, some standard bursting equipment isn’t able to break certain pipe materials. One good example is ductile iron.  This material is very tough and requires specialised treatment in order to be broken. Contractors need to add splintering tools to bursts the iron material. It’s most likely that there is misinformation when the old pipe isn’t the same with the plan.  

  1. The ground is toxic

It’s clear that sewer systems aren’t the most sanitised which is why cleaning it is essential. Hydro jets cleanse the sewer from impurities. The tool is also helpful in removing clogs that are found in the sewer line. Occasionally, a toxic ground will force contractors to delay their work. A more thorough clean-up is required and permissions to continue. It’s also likely that the pipes they’re supposed to be inserted will be changed. You see, some pipe materials aren’t suitable for toxic exposure while others can withstand chemicals and toxic corrosion for a long time.    

  1. The new pipe is damaged during the procedure

The new pipe can be impaired due to mishandling the equipment. Abrasions can also occur due to improper setup. It’s also possible that the new pipe is damaged during its insertion in the access point.
