Project Focus: Liquid Roofing Continued from page 34 Airport’s permission, a 53.5m high crane was used to lift three cages onto the roof, which were each filled with 25 flags at a time and then transferred into five large roll-on, roll-off skips. In total, 76 tonnes of flags were removed, revealing the rubber membrane underneath. Securing the membrane to the roof presented the next challenge. The flags had been installed onto plastic footings which, when removed, had left square prints which were still visible across the roof. These were used as the locations for 2,600 concrete fixings each measuring 122mm long with steel spreader plates, which were installed into the roof deck providing the required resistance to wind uplift. The next step was to wash the roof using power washers which, given its size, took just over a week. This makes it stronger and greatly reduces the risk of air bubbles under the fleece allowing the resin to saturate the fleece more quickly and improving the speed of application. The waterproofing was required around extensive detailing including gutters, outlets, pipe penetrations, and structures required for a large Above: Front of the hotel. The project presented some difficult challenges with regards to access to the roof area. window cleaning mechanism surrounding the roof, as well as anti-slip walkways. Adding to the challenges, the process required the removal of very wet insulation prior to the new insulation being installed and secured using the spreader plates and fixing screws. A large roof deck was also waterproofed which had been designed with a concave in the middle. When faced with bad weather and rain, the LRWA Awards 2022 finalist The Radisson Blu hotel project has been shortlisted for the LRWA Awards & Gala 2022, within the Liquid Roofing Project of the Year >1000m² category. Find out more about this year’s LRWA Awards at: www.lrwa.org.uk contractors were able to blow the water into the concaved centre area to continue the waterproofing and avoid any delays. Innovative thinking Further cost and time savings were achieved thanks to a two-metre safe zone and roof safety lifeline system developed by the roofing contractors. This avoided the need for costing scaffolding which could have cost over £100K and was used as an alternative to barriers which could have moved in the strong winds. The zone was created around the centre of the roof using large cones which were screwed into some of the flags that had been kept on the roof, preventing them from blowing off. These were then placed two metres from the edge of the roof with high visibility tape between each one. The contractors could work safely and freely to apply the waterproofing in this zone. For the final part of the installation, harnesses and long ropes were connected to the roof safety lifeline system. The roofing contractor’s creative thinking, skill and workmanship ensured the project was a success, overcoming many challenges. The liquid waterproofing has resulted in an aesthetic and highly durable finish which will remain watertight for decades, avoiding the risk of future costly repairs and maintenance.
