No spills, but all thrills

Retaining visitor numbers at Blackpool Pleasure Beach means maintaining the structures on the 42 acre site to a high standard, which is no small task.

FOUNDED in 1896, Blackpool Pleasure Beach is still one of the most visited amusement parks in the UK. Maintaining the structures on the 42 acre site to a high standard is critical to the success of the business with recent projects including upgrading two roofing schemes at the park with Kemper System’s Kemperol V210 waterproofing membrane. Opened in 2000 at a cost of £15m, the

Valhalla Viking-themed indoor water ride is one of the most popular attractions at Blackpool Pleasure Beach. Visitors queue for the ride next to an artificial rock face façade that features a ‘waterfall’ dispensing 12,000 gallons of water per minute. All of the water falls onto a roofed queuing area which was in need of repair. “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 needs a robust waterproofing membrane with no vulnerable seams and no risk of water penetration. The Kemperol V210 wet-on-wet system is ideal for such a demanding installation because it bonds to the substrate to form a monolithic membrane that cannot delaminate and has a BBA-accredited service life of 25 years,” says Tim Currey, construction manager at Blackpool Pleasure Beach. The Kemperol V210 was installed as an

overlay system. The existing substrate was cleaned and prepared ready to receive the liquid waterproofing resin using Kemper System’s D primer. The Kemperol V210 resin was then cold applied with rollers and a flexible reinforcement fleece was cut to size and shape on site and laid onto the wet resin. The installation team then rollered more resin on top of the fleece in a

single wet-on-were process to ensure complete saturation, and removing any creases or air bubbles before leaving the system to cure. The same system was used for the 1950s

Alice in Wonderland family ride, which was also suffering from water ingress in areas where the surface of its felt roof had split. The new waterproofing for the roof was

also carried out as an overlay project but areas of the roof that had de-bonded from the substrate had to be cut out and filled with a repair mortar made from Kemper System’s D Primer and sand. These areas were allowed to dry, creating a level surface onto which the Kemperol V210 system could be installed. The roofing system was then installed in the same way, with resin, flexible reinforcement fleece and resin applied in a single process and allowed to cure. “There is no such thing as a quiet time of

year at Blackpool Pleasure Beach so the contractor came in early for public-facing areas so that they could be off site by the time visitors started arriving at 10.30am. The Kemperol V210 enabled them to work on small sections at a time and manage the programme around the operational demands of the business while providing a robust, durable and flexible waterproofing solution,” says Currey. 25
