Manhole

Product
overview

Our manhole product is custom designed and manufactured to accommodate any size and shape of manhole possible, creating an exact match for an existing structure. The top transition section can be manufactured in a cone eccentric or concentric shape or any other shape as requested.

This product can also be designed and produced in multiple panel sections for ease of handling, transportation and installation.

Sections are joined together using a bell and spigot joint mechanism, and the joint is bonded with our high-performance resin adhesive, Channelbond. Once installed and grouted in place, the manhole forms a rigid fully-load-bearing structure, with a service life of 150 years.

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.

Industries

Applications

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.

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.

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.

Tunnels

Channeline’s capability to manufacture large-diameter, multi-segmental products enables the fully-structural rehabilitation of tunnels of any size.

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.
