wo of the popular rides at Blackpool Pleasure Beach have been upgraded to ensure they continue to thrill families of visitors for another generation thanks to Kemper System’s Kemperol V210 liquid waterproofing membrane.
Opened in 2000 at a cost of £15 million, indoor log flume ‘Valhalla’ is one of the 120-year-old Pleasure Beach’s most popular rides, offering visitors a thrilling Viking-themed journey.
The external façade features a ‘waterfall’ that dispenses 12,000 gallons of water per minute, splashing the covered waiting area below. It was this area of the ride that was upgraded with an overlay of Kemperol V210, a cold liquid applied waterproofing system that bonds directly to the substrate and forms a reinforced monolithic membrane that cannot delaminate and offers a BBA-accredited service life of 25 years.
Blackpool Pleasure Beach’s Construction Manager, Tim Currey, said: “The volume of water constantly pouring on the queue shelter roof for Valhalla is far in excess of what any roof would normally have to deal with, so it needed a robust waterproofing membrane with no vulnerable seams and no risk of water penetration.”
The Kemperol V210 cold liquid resin system was applied by roofing contractor, Castle Roofing, in a single wet-on-wet process, applying resin immediately followed by a flexible reinforcement fleece and then more resin to ensure complete saturation of the fleece before the membrane was allowed to cure.
The same system was used to overlay the roof of the theme park’s Alice in Wonderland family ride, which was originally constructed in the 1950s and was suffering water ingress in some areas. Here, Castle Roofing cut out sections of the existing felt roof where it had split, filling these areas will a repair mortar made of Kemper System’s D Primer and quartz sand, before installing the Kemperol V210 system as an overlay.
Tim adds: “The Kemperol V210 enabled the contractor to work on small sections of roof at a time and manage the programme around the operational demands of the business, while providing a robust, durable and flexible waterproofing solution.”
