LEISURE & HOSPITALITY
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 liquid waterproofing system is ideal for such a demanding installation because it bonds to the substrate to form a seamless, monolithic membrane that is completely impervious to water.”
“ALICE IN
WONDERLAND IS A POPULAR FAMILY RIDE, DATING BACK TO THE 1950S.”
Before work could begin, the flow of water on the ‘rock face’ was switched off to create a dry working area for installation of the new waterproofing membrane. Castle Roofing installed the Kemperol V210 as an overlay system, which reduced the programme and minimised disruption by avoiding the need for any strip out of the failed membrane.
The Castle Roofing team first cleaned the existing substrate and then prepared it to receive the liquid waterproofing resin using Kemper

System’s D primer. The Kemperol V210 resin was then cold applied with rollers in a single wet-on-wet process, with resin applied to the roof, reinforcement fleece laid in to the wet resin and more resin applied immediately on top to ensure complete saturation of the fleece, removing any creases or air bubbles as the application progresses. The system was then allowed to cure, creating a dark grey, seamless waterproof surface that can withstand the high volumes of constant water flowing down from the adjacent wall.

of water falling onto the roof of the ‘Alice in Wonderland’ ride, ensuring that the roof of this attraction was waterproofed effectively was no less important. A popular family ride, dating back to the 1950s, the attraction was suffering from water ingress in some areas where the surface of its existing felt roof had split, so an effective replacement waterproofing membrane was vital to protect both visitors and the internal features of the building.
The Kemperol V210 installation for this roof was also carried out as an overlay project to minimise disruption. Castle Roofing cut out areas of the felt roof surface that had de-bonded from the
substrate, filling these sections with a repair mortar made from Kemper System’s D Primer and Kempertec KR Quartz. These areas were allowed to cure, creating a continuous 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 more resin applied in a single wet-on-wet process and allowed to cure. The liquid system was ideal for the details and upstands on the roof as it can be applied to match the exact contours of the substrate and has excellent adhesion, even to vertical surfaces.
Throughout both projects, Castle Roofing worked around Blackpool Pleasure Beach’s opening hours to minimise disruption.
Tim added: “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.”
