When critical infrastructure begins to fail, traditional dig-and-replace methods are costly, disruptive, and time-consuming. At DL VEWS, we provide advanced trenchless solutions using the BulletLiner System® by CPM, allowing municipalities, engineers, and contractors to rehabilitate pressure pipelines quickly and efficiently—without tearing up roads, landscapes, or infrastructure.
The BulletLiner System is a close-fit, semi-structural liner designed for pressure pipes, delivering long-term performance while minimizing downtime and cost.
What is the BulletLiner System?
The BulletLiner System® is an innovative trenchless technology used to rehabilitate water, wastewater, force mains, gas, and industrial pipelines without excavation.
It works by installing a flexible fabric reinforced pipe (FFRP) inside an existing pipeline, creating a durable “pipe within a pipe” that restores structural integrity and extends service life.
Unlike traditional methods, this system:
Requires only two small access points
Maintains pipe diameter and flow capacity
Provides semi-structural (AWWA Class III) support
Is NSF 61 certified for potable water use.
DL VEWS provides Bullet Liner installation and consulting for:
This solution is ideal for pipelines located under:
BulletLiner eliminates the need for full trench excavation, reducing traffic disruption, permitting challenges, and environmental impact.
Projects can be completed at approximately one-third the cost of traditional dig-and-replace methods, making it ideal for budget-conscious municipalities.
50-year design life, corrosion-resistant internal barrier, and handles surge pressures up to 2x operating levels
Unlike many trenchless methods, BulletLiner is specifically engineered for: Force mains Water transmission lines Industrial pipelines
DL VEWS works alongside municipalities, engineers, and contractors to deliver data-driven trenchless solutions. With deep expertise in inspection, condition assessment, and rehabilitation planning, we ensure the right solution is applied to every project.
We don’t just install—we help you:
Bullet Liner is used to rehabilitate pressurized pipelines such as water mains, sewer force mains, and industrial pipelines without excavation.
While CIPP is widely used for gravity sewer lines, BulletLiner is specifically designed for pressure pipes, offering higher strength and performance in pressurized environments.
No—its close-fit design maintains flow capacity, unlike some sliplining methods that reduce internal diameter.
No—its close-fit design maintains flow capacity, unlike some sliplining methods that reduce internal diameter.
Only minimal excavation is needed—typically two small access pits, instead of full trenching.
Yes. The system is NSF 61 certified, meaning it is approved for potable water applications.
Costs vary by project, but it is typically significantly less expensive than pipe replacement, often around one-third of the cost.
