Lanes Rail gutter lining saves London Underground maintenance costs

Posted: Tuesday 13th January 2015

Lanes Rail is extending the life of drainage systems on London Underground buildings by introducing a gutter lining system that prevents leaks and avoids the need for roof assets to be replaced.

In 18 months, more than 2,000 metres of guttering at train maintenance depots across London have been lined in a programme of work that London Underground (LU) says has been a significant success.

It is the first time gutter lining, which supports sustainability by extending the life of roof assets, has been used on LU buildings.

Lanes Rail, part of Lanes Group, the national drainage solutions provider, is responsible for maintenance and repair of a wide variety of roofs and roof spaces across LU.

Lanes Rail Planned Maintenance Manager Mark O'Leary said: "We are always seeking innovative ways to solve maintenance problems efficiently and cost-effectively.

"The gutters were installed in the 1930s and 40s and are at, or beyond, their life expectancy. By lining them, we give them at least another 25 years of life, making this a very cost-effective repair solution."

Lanes Rail is using the UK-made Plygene Gutterline lining system. A pliable membrane is made-to-measure in the factory, so is joint-free. It does not use adhesives, or need structural work during its installation.

The liner can be fitted inside any shape of guttering. Downpipe connections are made waterproof by being sealed with a heat gun.

The gutter reline technique has been used, so far, on five London Underground depots - Acton, Ruislip, Upminster, Tufnell Park, and Hainault.

Mark O'Leary said: "We now have a full-time team working on gutter lining for London Underground. Maintaining roof drainage systems is a top maintenance priority, to protect buildings and maintain asset values.

"Rainwater getting into maintenance depots is a significant health and safety risk, and is detrimental to the welfare of maintenance staff. It has the potential to disrupt maintenance work, adding to LU costs and putting at risk the efficiency and quality of passenger rail services."
