Common Misconceptions about Pipe Bursting
Pipe bursting is a great way to replace pipes by using minimal excavation. Unfortunately, because it’s a pipe replacement method and has a bit of digging involved, people often dismiss this sewer pipe repair technology. There are a lot of common misconceptions in pipe bursting that should be eliminated; you can read about it below.
- Trenchless doesn’t mean it’s trench-free
Because of other methods in modern pipe repairs that have no digging at all, a few people consider pipe bursting as less effective to other pipe repairs since excavation is obligatory in pipe bursting. People need to understand that it’s ‘trenchless’ not ‘trench-free’. Pipe bursting is actually an effective pipe replacement method since it has 80-90% less digging than its traditional counterpart. Furthermore, there are cases in which other methods like inversion, pipe relining, and slip lining won’t be able to fully fix a sewer pipe since it’s collapsing due to severe damage. In this situation, the only way for the sewer system to become functional and safe is to replace the pipes.
- Comparing pipe bursting with other trenchless methods
Comparing pipe bursting with other trenchless methods is like comparing apples and oranges. You see, pipe bursting is under trenchless replacement technology while CIPP, CML, PIPP, and other popular pipe repair methods are under trenchless rehabilitation.
- Pipe bursting must only be done if the pipe can’t be dug
It’s a common misconception that pipe bursting should only be applied if the pipes are impossible to be excavated, when in fact this method can actually be used in various situations such as; pipes that need replacement is located at areas that have heavy traffic, replacing pipes in conventional methods is too expensive, interruption against public area must be avoided, and many more.
- HDPE is the only pipe used in pipe bursting
When it comes to pipe bursting using the pneumatic method then HDPE is required, but for static pipe bursting, other pipes like thermally fused PVC, restrained joint PVC, and among others are actually utilised. Therefore, HDPE isn’t the only pipe applicable to general pipe bursting.
- It can only be used to enlarge the diameter of the sewer line
The pipe bursting application may increase the diameter of the sewer line through the use of the force from bursting, but that doesn’t mean it should only be applied for expanding a sewer pipeline. Pipe bursting has something called “size on size” pipe which basically means that the replacing pipe has the identical proportions of the old pipe.
- It is very costly
In the past, pipe bursting may be considered as an expensive pipe repair technology since it wasn’t much a popular method and the equipment that was needed is not readily available. Because of this occurrence, people immediately conclude that pipe bursting is expensive. Also, the notion that pipe bursting is only used when digging wasn’t possible for a project made it gain an “exclusive” and costly reputation. However, pipe bursting today has become more applicable and affordable.
