Reliable under

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 products are a fully-structural rehabilitation solution for stormwater drainage systems. Our unique technology means that our solutions are much thinner than standard GRP linings, maximizing the possible cross-sectional area. Plus, the smooth lining of Channeline products has been shown to increase hydraulic capacity by up to 25%, so stormwater drainage remains effective for flooding and other extreme events.

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.


Fully-structural solution, any shape, any size, 150-year service life

Bespoke design to maximise cross-sectional area

Multi-segmental capabilites for logistical and installation benefits
