Channeline - Slip Liner

We use in-line high-strength joints with solid wall gaskets, ensuring easy connection and a reliable pressure-tight seal.

Our optional mounted centralizing skids simplify the correct positioning and jacking of the liner. Straight line lengths of 1,000 m (3,280 ft) and more can be accommodated in a single jacking process.

Our slip liners are also available in a multi-segmental version, whereby the pipe is produced in three separate segments that can be assembled on site, thereby enabling a substantial reduction in transportation costs. The panels are joined with our patented tongue and groove system, and bonded using our high-performance resin adhesive, Channelbond.

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.

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.

Live flow installation
Thanks to slip-line entry, this product is able to be installed with live flow. That means no need for bypass, reducing time, cost and disruption to local communities and the enviornment

Long-length jacking
Our GRP can sustain vast jacking loads, meaning lengths of 1,000 m can be inserted from a single point. This means fewer access shafts are required, reducing time, cost and disruption.

Installation expertise
Channeline can offer expert assistance, advice and jacking equipment to aid the successful installation of slip liners.
