The Top 3 Pipe Bursting Myths
Trenchless pipe replacement solutions are mostly used when the other classifications of trenchless sewer line repair–the trenchless pipe rehabilitation methods–cannot be applied in some sewer pipe problems. Pipes that are corroded, crumbling, or on the verge of collapsing are impossible to rehabilitate because of its fragile condition.
A better and more effective solution is to replace the pipes with the use of trenchless pipe replacement methods; since it’s far more effective and removing the old pipes can be done easily. The excavation done in trenchless pipe replacement is far lesser than the usual open excavation that actually destroys the property. A popular method that belongs to trenchless pipe replacement is pipe bursting. There are a lot of misconceptions and false information surrounding this method. Learn more of the top pipe bursting myths below.
1. Pipe bursting can be only applied if the pipes are impossible to excavate
Although this is one of the situations in which using pipe bursting is optimal, there are actually many conditions in which this method is very applicable like:
- Repairing the damaged pipes is needed but extensive excavation is too costly and must be avoided
- High volume of traffic in the surrounding work site
- The repair must be done as quickly as possible
- Interruption from the pipe replacement must be kept at minimal or zero
- The size of the whole pipe structure needs to be increased
2. It’s messier than pipe relining or other pipe rehabilitation techniques
There are some situations in which before a pipe bursting is started, there must be certain dig sites needed to be created first, this is due to the fact that there was no suitable entry point for the new pipe, or a collapsed section of the main pipeline needs to be taken out. You really can’t compare pipe bursting with pipe relining or any other pipe rehabilitation method out there since they’re completely different solutions in pipe repair. Of course pipe bursting is a tad bit messier, it’s because the pipes need to be removed the main pipeline, while rehabilitation techniques will only insert a pipe structure or liner to take over the sewer pipes.
3. Pipe bursting is very expensive and must be a last resort when it comes to pipe replacement
Back in the 2000’s, pipe bursting was indeed expensive since it wasn’t widely practised among contractors and the method wasn’t refined yet. Today, pipe bursting is one of the most affordable solutions offered under trenchless pipe replacement. In fact, the entire cost of using pipe bursting is significantly lower than major excavation pipe replacement. The reason for this is that the excavation needed in pipe bursting is actually too small to be considered a destructive process–it’s even a negligible amount of digging. Pipe bursting is a competitive and economical replacement procedure which has a lot of benefits. It continues to become a favoured choice when replacing pipes.
4. HDPE is the only pipe used in pipe bursting
This is a very common myth or misconception when it comes to pipe bursting. HDPE is the only pipe used in the pneumatic type of bursting method. Static pipe bursting on the other hand can use different types such as PVC, ductile iron, and many more.
