Firestone completes remote hostel roof in The Lakes
he Lake District is almost as famous for rain as it is for its scenic beauty and waterproofing specialist, Firestone, has helped to protect against the former while preserving the latter at the YHA’s Black Sail Youth Hostel in Ennerdale. Only accessible on foot or by bicycle, with just 16 beds, no electrical sockets and scant mobile phone signal, Black Sail is the most remote of the YHA’s hostels and amongst its most picturesque. The re-roofing scheme not only needed to be robust enough to cope with the high levels of rainfall and the youth hostel’s exposed location, it also needed to be flexible enough to accommodate the penetrations on the substrate for the building’s solar panels, solar heating and solar tubes.

The chosen system also had to be suitable for a green roof
installation and Firestone’s UltraPly TPO waterproofing membrane met the bill for all these criteria. The system was installed by
Firestone licensed contractor,
Goodwin Roofing Ltd, and the company had to
overcome the challenges of the project’s remote location, two and a half miles from the nearest road, and its unpredictable micro-climate in the shadow of one of the region’s most famous peaks, Great Gable. Comments Jeff Goodwin from Goodwin Roofing: “A reinforced membrane of flexible Thermoplastic polyolefin (TPO) that contains neither plasticisers nor halogens, Firestone UltraPly TPO offers the excellent waterproofing performance required for such a demanding location, combined with low environmental impact and ease of installation.”

New Seashell Trust Heating Scheme benefits from Flexalen Pipe Technology
C
PL Building Services chose Flexenergy's Flexalen pipework to install a new underground district heating system for the Cheshire-based charity, Seashell Trust.
The charity provides a creative and secure environment for children and adults with complex and severe learning disabilities, which include little or no language abilities. It is home to the Royal School Manchester, a non-maintained special school, and the Royal College Manchester, an independent specialist further education college. Both the school and college are residential and the new heating scheme will initially serve nine houses from an energy centre, but has capacity to supply another phase of houses and other buildings. The installation was part of an ongoing redevelopment of the site – part of the charity's £20 million Transforming Lives Appeal – and didn't come without its challenges; a high water table meant that the ground was frequently waterlogged
making conditions problematic and often impossible for laying new pipework. "Cost, quality, efficiency and our previous experience of working with Flexalen pipework were all important factors when choosing the best pipework for this project," explains Geoff Ferguson, Senior Project Engineer at CPL.
"The Flexalen pre-insulated pipe system installed was the ideal technology for this situation being lightweight and highly flexible making it easier to install, especially in the often atrocious ground conditions we were faced with. The water tight bond between the corrugated outer pipe and the polyolefin insulation offers additional protection against water seeping in, helping to maintain the robust technical qualities of the pipe system."
As a result of this project, the Seashell
Trust now benefits from an efficient heating system with low carbon emissions and pipework that is guaranteed for 50 years.

D
rainage survey camera technology provided by Lanes Group has been used to carry out a structural inspection of one of the deepest railway tunnel shafts in the UK.
A CCTV drainage survey team supported the inspection of the 120m ventilation shaft for the Ffestiniog tunnel on the Conwy Valley Line in Snowdonia, North Wales. The tunnel is Britain's longest single track railway tunnel,
as well as Britain's longest natural rock rail tunnel. The Lanes Group team's ROVVER robot drainage survey camera was lowered down its ‘Number 2 Shaft'. It recorded HD quality video footage of the oval brick and stone shaft which could then be viewed by civil engineers as part of a planned maintenance programme. Ian Clapham, Area Development Manager for Lanes Group's Chester depot, which carried out the work, said: "This is a more unusual use for our CCTV drainage survey team. It shows the wide range of applications our CCTV camera technology can be used for. If you need to survey or inspect something inside a pipe, shaft or chamber, whether underground or not, we can almost certainly help.
Safer
"The success of this project demonstrates how using this method to inspect deep shafts is safer and generates better data for assessing the structure's condition." Lanes Group was commissioned to support the shaft inspection by engineering consultants Amey, working on behalf of Network Rail.
The Ffestiniog tunnel is 2.1 miles long and takes the Conwy Valley Railway under Moel Dymogydd, a 1,700ft high mountain close to Blaenau Ffestiniog. The previous survey, in 2012, had been carried out in the conventional manner, by an operative abseiling down the 393 ft deep shaft, checking the structure and taking pictures as he went.
Methodology However, a review of the risk assessment and methodology for the work resulted in a decision to carry out the inspection remotely, to avoid risks associated with rock falls in the shaft.
The Lanes Group CCTV drainage survey team worked with a rope access team on the project, supervised by Amey's project manager. The mainline drainage survey camera was prepared by the Lanes drainage engineers, then attached to a rope and taken into the shaft by the rope access team.
The camera's wide angle lens recorded HD quality footage of the entire shaft as it was lowered down the shaft, which is 1.5m wide and brick-lined at the top and rock-walled at the bottom.
The Lanes team and Amey's structural engineer viewed the images on the camera system's screen back on the surface, giving directions to the rope access team to hold the camera in position or change the speed of descent. Ian Clapham said: "The whole process was completed in a day, providing Amey with excellent images they can use to prepare their survey report. "If necessary, we could attach a laser profiling tool to the camera, which would create a highly accurate laser- generated sectional image of a shaft, allowing precise measurement of its dimensions, distortions and structural defects."
