FP McCann designs and manufactures a bespoke range of both Trapezoidal and Expanded Segmental Smoothbore tunnel linings, designed to provide durability, speed and ease of installation in tunnel construction.

Trapezoidal tunnel linings are developed to work alongside technologically advanced tunnel boring machines, with linings designed and manufactured to suit exacting project requirements.

Tunnel segments can be modified to suit a variety of joint fixings, segment thickness and tunnel diameters. The latest manufacturing techniques incorporate steel fibre dosing to guarantee high quality, reliable product. The wedge-shaped design of individual segments eliminates the requirement for a special closure segment.

FP McCann has the in-house expertise to manufacture concrete moulds to meet the latest BTS specification. Alternatively, projects can be supplied utilising specialist manufactured steel moulds, if required.
