As part of the Railway Upgrade Plan, Network Rail have invested £50 million into the restoration of stations across the North Wales Coast. Polyroof were chosen to help restore Rhyl railway station to its former glory.
Long standing and rich in history, Rhyl railway station underwent many changes throughout the 19th and 20th Century, expanding its tracks to deal with the huge increases in traffic mostly due to the North Wales Coastline including Rhyl becoming a popular holiday destination.
Only two platforms presently remain at the station due to changes in tourist habits and various new forms of competition, however the station continues to serve as a key station on the Chester to Holyhead line.
The specified areas that were in need of refurbishment included the roof over Platform 2 and the bridge/walkway roof which connected the two platforms. The existing waterproofing on these areas consisted of built-up felt with a mineral cap sheet, which was in an aged condition and beginning to show signs of failure such as splits and blisters. Leaks were now beginning to occur which were in danger of affecting the condition of the roof structure itself.
The survey conducted recommended that the roofing areas would benefit from the installation of a high-performance waterproofing system as a long-lasting protection system for the roof and provide guaranteed protection against further leaks.
Based on the findings of the survey conducted by Polyroof Technical Services, a bespoke specification was designed that would eliminate the current issues through the installation of the BBA-approved Protec system. Due to the roof being situated above unheated areas, there was no requirement for new insulation within the build up.
Firstly the existing built-up felt was stripped and removed from site to expose the original close-boarded timber which was inspected for defects, made good where required and retained where possible. Defective areas where replaced with new timberwork as required. In order to provide a sound, solid substrate a new OSB3 TG4 deck was mechanically fixed across the whole area within a phased approach, ensuring the roof was kept watertight as works progressed.
The Protec system was then applied directly to the timber; with its RapidcureTM technology large areas where able to be made fully waterproof within short periods of time. Polyroof Technical Services visited site regularly to ensure works were being completed to the high standards required and regular reports were fed back to the client.
Upon completion a final inspection by Polyroof led to the roof being signed off and guaranteed, giving the client complete peace of mind that their roof will be fully watertight for at least the 20 years.
