Standard liner
Multi-segmental liner
Product
overview
Our multi-segmental liner product uses panels manufactured in two or more longitudinal sections. The panels are then bonded on site, above or below ground, using our patented tapered tongue and groove longitudinal joint and a bell and spigot radial joint, positioned at the points of intersection. Once the segments are assembled using our high-performance resin adhesive, Channelbond, our multi-segmental liner provides the same structural performance as a Channeline liner manufactured as single piece, with a service life of 150 years.
Our multi-segmental liner is an ideal solution where transportation problems, access difficulties (for example, entry only via manholes), or particularly large structures make it hard to produce and install the product in one panel.
Why
Channeline?
Unrivaled experience
Channeline has over four decades of experience specialized in the design and manufacture of circular and non-circular buried infrastructure for our clients worldwide.
150 year service life
Longevity is important to us, and a key part of our vision. Our products have been proven via independent testing (using the long-term creep retention test) to have a service life of at least 150 years.
Any shape, any size
Our completely bespoke design and manufacturing capabilities mean we can provide fully-structural liner products at any shape, and any size. We also offer multi-segmental products that are perfect for large-diameter projects or more complex logistical needs.
Thinner than standard GRP
Our patented technology uses a sandwich panel method combining a unique polymer and aggregate core. This means that our product is remarkably stiff and strong, but with a relatively thin wall. This is important as we maintain as much cross-sectional area as possible.
How we work
Project evaluation
Our expert team take care to understand the requirements and nuances of each project. This usually involves surveying the host pipe, which we can help arrange, and a site visit.
Bespoke design service
Our in-house design team creates a custom design to fully satisfy project requirements and specifications. If required, the design can be validated using finite element analysis.
Manufacture, with quality in mind
The bespoke manufacture of product begins. Quality control is undertaken both during and on completion of the manufacturing process. If required, third party inspection and validation can be arranged.
Dedicated logistics support
The finished solution is prepared for shipping and dispatched to the project location. Our dedicated logistics team and client liaison provide end-to-end support until the arrival of goods.
Installation supervision
Training and support for installation can be provided by our team on request.
Product features
Logistical advantage
Thanks to their smaller size and ablity to be nested, our multi-segmental liners reduce transportation costs and enviromental impact.
Ideal for larger diameters
Many large diameter pipes simply can't be manufactured or transported in one piece. Our multi-segmental liners offer a solution to this problem.
Installation benefits
Easier installation compared to a one-piece large diameter pipe means that this product offers cost savings in time, as well as reduced impact on local communities, for example road closures.
Industries
Applications
01
Wastewater
Buried, large-diameter pipelines and culverts have represented the backbone of any city’s utility network, in some cases for hundreds of years, but many of these are failing due to age. Channeline's fully-structural rehabilitation solutions give a new life to existing structures.
02
Stormwater
Heavy rainfall and impervious surfaces such as roofs and asphalt roads leading rain directly into sewer systems often cause sewers and wastewater treatment plants to reach their full capacity. An effective and reliable network of stormwater drainage infrastructure is needed to combat this challenge. Channeline offers a fully-structural rehabilitation solution for stormwater drainage systems.
03
Rail and road culverts
Culvert design has to consider a number of factors like the weight of the surrounding soil and roads, the soil type of the foundations, and the expected water properties including their flow rates. Channeline products are custom designed and manufactured, meaning we can take all of these factors into consideration, producing a fully-structural solution that effectively rehabilitates each unique culvert.
04
Seawater cooling networks
Usually seawater cooling systems use steel pipes and replacement is very expensive. Channeline offers a cost-effective alternative to replacement, instead rehabilitating the existing structure using our fully-structural liners.
05
Tunnels
Channeline’s capability to manufacture large-diameter, multi-segmental products enables the fully-structural rehabilitation of tunnels of any size.
06
Custom
Channeline excels in crafting bespoke solutions tailored to meet diverse client needs. Leveraging cutting-edge technology and extensive expertise, we meticulously design and manufacture custom products for various applications.
