A high-performance approach to modern pipeline rehabilitation

As infrastructure ages, pipeline owners are under increasing pressure to maintain performance while reducing cost, disruption, and downtime. This is where trenchless pipeline rehabilitation has become a critical solution.


Rather than replacing pipelines entirely, trenchless methods allow operators to restore and extend the life of existing systems with minimal excavation. For pressure pipelines in particular, the right rehabilitation approach must balance structural performance, flexibility, and long-term reliability.


The BulletLiner System® is a close-fit, semi-structural liner designed to meet these demands. As the only close-fit system that meets AWWA Class III requirements, it can function independently or work in conjunction with the host pipe to increase overall pressure capacity.


Common challenges in pipeline rehabilitation

Pipeline rehabilitation projects are rarely straightforward. Many systems were not designed with modern access or repair methods in mind, which creates a range of challenges during rehabilitation.


Typical issues include:

  • Aging infrastructure with reduced structural integrity

  • Bends, diameter changes, and complex geometries

  • Limited access points and difficult installation conditions

  • The need to maintain service during rehabilitation

  • Budget constraints and pressure to reduce project timelines


These challenges make it essential to choose a solution that can adapt to real-world conditions without compromising performance.


Built for real-world pipeline conditions

Trenchless solutions must be able to perform in environments that are far from ideal. Flexibility during installation and consistent structural performance are both critical.

The BulletLiner System® is engineered to navigate complex pipeline conditions while maintaining its integrity.


Key capabilities include:

  • Installation across long distances

  • Ability to move through bends and challenging geometries

  • Reliable performance in varied pipeline environments


Because it is a trenchless solution, installation requires minimal excavation. This helps reduce disruption to surrounding infrastructure, traffic, and ongoing operations, making it especially valuable in urban or high-demand settings.


Improving efficiency without compromising performance

One of the primary advantages of trenchless pipe rehabilitation is the ability to complete projects faster and more efficiently than traditional methods.


Compared to dig-and-replace approaches, trenchless solutions can significantly reduce both cost and project timelines.


With the BulletLiner System®, operators can achieve:

  • Up to 75% cost savings compared to full replacement

  • Shorter installation timelines

  • Reduced system downtime and service interruptions


This combination of speed and performance allows infrastructure owners to address pipeline issues while maintaining continuity of service.


Designed for long-term reliability

Pipeline rehabilitation is not just about resolving immediate failures. Long-term performance is a critical part of any successful solution.


The BulletLiner System® is designed with a 50-year service life and is backed by a 5-year warranty, supporting long-term infrastructure planning.


Performance benefits include:

  • Ability to operate independently of the host pipe

  • Increased pressure capacity when used alongside existing infrastructure

  • Consistent performance under demanding conditions


This approach helps extend the life of existing assets while ensuring systems can meet future demand.

 

Supporting a more sustainable approach

Sustainability is an increasing priority across infrastructure projects. Trenchless rehabilitation plays a key role in reducing environmental impact while improving efficiency.


By minimizing excavation and preserving existing infrastructure, trenchless solutions help reduce overall project impact.


The BulletLiner System® supports this approach by:

  • Limiting surface disruption and excavation

  • Reducing the carbon impact associated with full replacement

  • Extending the usable life of pipeline systems


These factors contribute to a more sustainable and cost-effective asset management strategy over time.


Why it matters

Choosing the right pipeline rehabilitation solution has a direct impact on cost, performance, and long-term reliability. Solutions that can adapt to complex conditions while minimizing disruption are becoming essential.


The BulletLiner System® provides a trenchless option that aligns with these needs, helping operators restore performance, extend asset life, and plan more effectively for the future.
