Pipe Bursting
Trenchless Pipe Bursting — A Modern Way to Replace Underground Pipes
Tell us what you need
Replace aging underground pipes.
Minimal disruption compared to traditional excavation.
Overview
Full Pipe Replacement Without Digging
When your underground water pipe or sewer line has reached a point where repair is not the best option, replacing it becomes the only solution. However, replacing it does not always mean you will need to disrupt your entire yard, as the process will require large trenches, heavy equipment, and extensive property restoration. Thanks to trenchless pipe-bursting, a modern replacement method that replaces aging underground pipes with brand-new ones with minimal disruption compared to traditional excavation.
This trenchless replacement method does not dig long trenches to remove old pipes; instead, it creates small access pits at each end of the damaged section to break apart the old pipe while simultaneously installing a new one in its place. A specialized bursting head is used to break the old pipes outward into the soil around them. Simultaneously, new pipes are pulled and installed.
Since the replacement is done on the old pipe path, technicians need only a few entry points instead of excavating the entire length and breadth of your yard. This way, a full pipe is replaced without extensive disruption as in the traditional method.
Whether you are struggling with a collapsed sewer line, experiencing tree root intrusion, or your pipeline has reached the end of its lifespan, a professional pipe-bursting service is the most preferred replacement solution designed to last for a long time. Seek a reliable trenchless pipe-bursting service to restore your underground plumbing while preserving much of your property’s landscaping, sidewalks, and hardscaping.

How Trenchless Pipe Bursting Works
Trenchless pipe bursting is a surprisingly simple process and not as complex as it sounds. Experienced professionals follow a tried-and-true method instead of removing damaged pipes one by one. Specialized equipment is used to break the pipes apart underground and simultaneously install a brand-new pipe on the same path. The process is designed to be efficient while minimizing disruption.
Here is how the process is undertaken.
01
Initial Inspection
02
Create Access Points
03
Insert Pulling Rods or Cable
At this step, a pulling system is fed through the existing pipe. This may involve hydraulic rods, steel cables, or a specialized pulling mechanism, depending on the equipment in use.
04
Bursting the Existing Pipe
A bursting head (or expander head), attached to the pulling system, is guided through the existing pipe. As it moves forward through the old pipe, the head expands and breaks the damaged pipe material outward into the surrounding soil.
Simultaneously, the new replacement pipe is pulled into the exact path of the original pipeline and connected directly behind the bursting head. Thus completing the pipe-bursting sewer replacement process in a single continuous operation without entire-premise excavation. The replacement pipe is installed in one continuous length, hence, it has fewer joints and a lower risk of future leaks.
05
Final Inspection
Less digging. Better direction.

When Is Pipe Bursting Recommended?
Not all plumbing problems are the same. Hence, one rule does not fit all! Trenchless pipe bursting is an ideal option for fully replacing your pipeline with brand-new pipes when selective repair of damaged pipes is no longer sufficient.
A pipe-bursting service is the best option when:
- The sewer line has suffered a serious structural failure.
- The existing pipeline has severe cracks or is broken.
- Certain sections of pipe have cracked or are close to falling apart.
- The life span of the pipe has reached its end.
- Multiple and frequent repairs are no longer sufficient to solve ongoing problems.
- The existing pipe material has worn out beyond normal repair.
- Tree root intrusion has caused widespread foundational damage.
- The overall condition is prone to failure.
- The existing pipe diameter is not enough for the property's needs.
- The existing pipeline requires replacement with a larger diameter.
One of the key positive aspects of pipe-bursting sewer replacement is that it installs an entirely new pipe by removing the old and damaged pipeline. This removes long-term future complications that come with faulty plumbing systems.
When Pipe Lining May Be a Better Option
Pipe lining is another trenchless solution used for a different application. Instead of replacing the pipe, pipe lining repairs an existing pipe by creating a new interior surface inside the existing pipeline by installing a resin liner inside it. This method is effective when the original pipe still has sufficient structural strength to support its overall shape.
However, if the pipe has collapsed or is severely damaged, lining may not be feasible due to missing structural support. In such a condition, pipe-bursting sewer line replacement is the more practical long-term solution. Pipe bursting installs entirely new pipe instead of repairing the existing one.
Comparison
Pipe Bursting vs. Pipe Lining
Both trenchless pipe bursting and pipe lining are advanced trenchless technologies, but which one you choose depends on your plumbing problems.
Objective
Completely new pipe replacement.
Restore the internal problems in the existing pipeline.
Best option for critically damaged or broken pipes.
Needs a reliable host pipe.
Yes.
No.
No.
Yes.
Often feasible.
Usually, this is not possible.
Often feasible.
Usually no.
Small access points
Minimal access points
A new pipeline can last for decades, depending on the material.
Excellent when installed correctly.
Extensive damage, replacement needs, failed pipes, and upsizing.
Minor to average structural defects, like cracks, minor leaks, root intrusion, etc.
If your existing pipeline has sufficient piping strength, trenchless pipe lining may be a faster and more cost-effective rehab option. However, when damage is severe and beyond minor correction, complete replacement is necessary. Pipe-bursting sewer line replacement is preferably the most suitable trenchless option for a long-lasting solution with minimal disruption.
Materials
Materials Used for Pipe Bursting
The quality of materials used largely determines the effectiveness of a new sewer line. Generally, pipe bursting services use durable materials that can ensure consistent performance for decades.
HDPE
High-Density Polyethylene (HDPE)
HDPE is the most widely used material for trenchless pipe-bursting projects, as it offers excellent strength, robustness, and flexibility.
The benefits include:
- Corrosion resistance
- Highly durable
- Excellent impact strength
- Flexible
- Root-resistant
- Heat-fused joints that minimize leak possibilities
These factors ensure the underground pipeline can handle decades of normal daily use.
PVC
Other Suitable Materials
PVC is another common choice, depending on project requirements, installation conditions, and local codes. PVC can be a great alternative, as it offers smooth inner walls, exceptional robustness, and lasting corrosion resistance. What replacement material is right for a project depends on factors like pipe size, soil quality, utility requirements, project specifications, and municipal standards.
Your contractor can determine the most suitable material for your property's plumbing system.
Pricing Factors
Cost Factors & Typical Price Ranges
The cost of trenchless pipe bursting sewer replacement depends on the specific factors of a project instead of a single flat rate.
Usually, contractors estimate the costs of a project based on the total length of the pipeline (price calculated per linear foot) and also by region. Overall investment may differ according to factors like accessibility, soil conditions, pipe depth, pipe diameter, local labor rates, installation complexity, and restoration needs. An on-site inspection by an experienced professional ensures the most accurate estimate.
Factors that influence the final pricing include:
- Length of the pipe
- Pipe diameter
- Existing pipe material
- Installation accessibility
- Ease of equipment access
- Underground obstacles
- Installation depth
- Soil conditions
- Permit requirements
- Site restoration after installation complexity
- Region
Inspection-first pricing.
Although trenchless replacement may have a higher initial cost than a temporary repair, many property owners appreciate the reduced excavation, shorter project timeline, and lower landscaping restoration costs.
Although a professional pipe bursting service may involve a higher upfront investment than isolated spot repairs, it often reduces the overall project cost by minimizing excavation and restoration work.
