Zink FLAT ROOFING & WATERPROOFING 01992 801927 www.almhm.co.uk Waterproofing solution takes centre stage at Capital theatre refurbishment in Greenwich When the roof of a popular London theatre was no longer watertight, cold-applied liquid waterproofing specialist Kemper System provided the ideal solution. Roofing contractors Capital Roofing Co, of Blackheath in Greenwich, specified Kemperol 2K-PUR to refurbish the existing 500m² asphalt roof at the Greenwich Theatre, South East London, to stop water ingress into the four-storey building. The company says Kemperol 2KPUR was an obvious choice for refurbishment works on the occupied building thanks to its solvent-free and odourless qualities. In addition, its quick installation benefits meant Capital Roofing Co was able to meet its tight project deadline, and the works on the theatre were completed in time for the start of the festive show season. Once Capital Roofing Co carried out extensive repairs and cleaned the surface, they primed the existing roof surface then applied the Kemperol 2K-PUR resin in a single wet-on-wet process. The coldapplied resin was rolled onto the roof with a reinforcement fleece laid directly into the wet resin, immediately followed by more resin to ensure complete saturation of the reinforcement fleece. Once cured, the resin formed a seamless, elastomeric waterproof membrane that cannot delaminate, is UV stable and bonds directly to the substrate. Because the Kemperol 2K-PUR system can be used for complex detailing, this meant a new, up-andover 068 MAY 2017 RCIMAG.COM staircase was able to be installed whilst still providing a seamless liquid waterproofing solution. A Kemperdur anti-slip walkway for safe maintenance traffic was added to complete the waterproofing works. The installation team at Capital Roofing Co completed the refurbishment of the Greenwich Theatre roof on time, to budget and specification. Chris Shulver, of Capital Roofing Co, said: “The existing roof at the theatre was failing, resulting in water leaking through onto the seats inside. We had some very tight deadlines to adhere to, which is why we choose Kemperol 2K-PUR because of its quick and easy installation system. “The fact that the waterproofing solution is eco-friendly as well as odourless was an added bonus for the client, as work was able to be carried out whilst the building was still occupied. The theatre could carry on as normal with minimal waste removal or nuisance odours to disrupt employees or guests to the theatre, and without the fire risk of hot works. “With a BBA accredited 25-year service life, Kemperol 2K-PUR provided the ideal solution for the Greenwich Theatre refurbishment.” Greenwich Theatre is a popular, local playhouse located in Croom’s Hill, close to the centre of Greenwich in South East London. The theatre first came to Greenwich at the beginning of the 19th century during the famous Eastertide Greenwich Fair at which the Richardson travelling theatre annually performed. Since then, it has seen the likes of Mia Farrow, Charles Dance and Susannah York perform. www.kempersystem.co.uk The waterproofing on the roof of footwear manufacturer Hotter Shoes’ head office and manufacturing facility in Skelmersdale, West Lancashire, had exceeded its serviceable life and begun experiencing significant water ingress, requiring urgent remedial work. Prior to any work commencing on site, Bauder undertook a condition and moisture mapping survey of the roof area to help identify the exact extent and locations of water ingress so that a fully-informed decision could then be made to best suit the client’s needs. As a result, the optimal solution was for approved contractor BBR Roofing to strip off the existing deteriorated and delaminating, oxidised bituminous capping sheet and overlay the underlayer with 12,500m² of Bauder’s two layer bituminous system Bauderflex. The company says this partial strip allowed for a quick and undisruptive installation, which was important to the client as they wanted the factory below to remain fully operational throughout. One of the major challenges for this project was the quantity of intricate detailing requirements given the sheer scale of the roof. As part of the necessary works, redundant vents and associated frameworks also needed to be removed and replaced prior to new cladding being added to the perimeter and 69 of Bauder’s structural glazed units being expertly fitted to give essential daylight to the building’s interior. Moreover, asbestos was found within the redundant vent apertures and therefore required specialist disposal. Because the factory workers have variable shift patterns it meant that the roofing works programme had to be regularly changed and all deliveries needed to be timed as not to conflict with vehicles moving in and out of the facility. However, despite the logistical challenges encountered, all works were completed on time and to budget, much to the delight of the client. Upon completion, an additional moisture mapping survey was performed to confirm to the client that the overlay was performing as specified and the roof was now completely watertight. Andy Glover, health safety & facilities manager at Hotter Shoes, stated: “The readings from Bauder’s moisture mapping survey provided us with objective information and a visual representation of the exact condition of the roof, enabling us to take the best remedial action and save money in the process. The resulting overlay solution was expertly installed without causing any disruption to ongoing work at our facility. We are delighted with our refurbished roof and the technical support we received throughout.” www.bauder.co.uk/roofsystems/ refurbishmentprojects/ roof-survey-anddiagnostics Hotter Shoes starts off on the right foot Copper Stainless The optimal solution was for approved contractor BBR Roofing to strip off the existing deteriorated and delaminating, oxidised bituminous capping sheet and overlay the underlayer with 12,500m² of Bauder’s two layer bituminous system Bauderflex Because the Kemperol 2K-PUR system can be used for complex detailing, this meant a new, up-and-over staircase was able to be installed whilst still providing a seamless liquid waterproofing solution
