The Macallan installs Flowcrete flooring
THE new distillery for luxury whisky brand The Macallan has installed Flowcrete UK floors to create surfaces to reflect its visual identity and maintain the functional properties required to produce the iconic product.
When Edrington, the international spirits group that owns The Macallan, decided to build a £140m facility to meet increasing global demand, it knew no ordinary site would suffice.
Instead, Edrington worked with the architectural practice Rogers Stirk Harbour + Partners to build an architectural monument on The Macallan’s traditional Speyside estate to house a distillery and visitor centre.
The development consists of five cells that seamlessly blend into the surrounding countryside as undulating, green-roofed earthworks. Four would house the brand’s production operations (three still houses and a mash house) and one would be the visitor centre.
The distillery would merge The Macallan’s centuries old traditions with cutting-edge thinking in a way that allows visitors to see each step of the process, surrounded by a sustainable, luxurious environment. This meant creating a facility to meet the challenging industrial concerns inherent to making some of the world’s best whisky while constantly conveying an inviting, on-brand aesthetic.
This was a challenge for the floor area in the four production cells that house the copper stills, mash tuns, stainless steel wash-backs, distillation and fermentation vessels, pipes and assorted distillery apparatus. The flooring in these areas will likely face spillages of hot, corrosive by-products alongside point loading from heavy equipment, frequent foot traffic, intensive cleaning, impacts and more.
George McKenzie, Edrington’s UK engineering manager, said: ‘We look on Macallan as a world luxury brand, and so the whole feeling and aesthetics, including the floorcoverings, had to match that.’
To ensure the surface would maintain a functional, visually attractive finish, 5,570sq m of the polyurethane system Flowfresh HF LT was applied. ‘This robust, chemical resistant system would be able to withstand the onsite conditions and provide additional benefits such as easy cleanability, slip resistance and an in-built antibacterial agent,’ says the company.
A sleek grey colour was chosen to match the production area’s industrial aesthetic. The application of the Flowfresh HF LT around the intricate pipework was tricky, but thanks to the easy applicability of the system, the floor was completed on schedule and to The Macallan’s exacting standards.
George added: ‘During the commissioning of the process area, we’ve had spillages of alcohol, malt, malt dust, caustic, which are all pretty hard on the floorcoverings and the floors are still pristine.’
Visitors to The Macallan’s whisky tour would not only experience Flowcrete UK flooring in the production areas, as its screeds and decorative finishes were widely applied.
Before the resin finishes could be applied, 3,669sq m of Isocrete K-Screed and 4,890sq m of Flowscreed Industrial Top were used to create robust screed layers that would provide level and reliable platforms for the decorative coatings.
The main internal tourist routes and viewing gallery were then coated with the fast curing, methyl methacrylate (MMA) resin floor topping Flowfast Quartz Structure. This system combines decorative colour stable quartz granules in a clear resin binder to create a durable floor with an attractive, textured finish.
A stony, dark grey shade was chosen to match the natural tones and hues of the site. This choice was also a great way to use the floor as a backdrop on which the colours of the timber roof, copper stills, wooden barrels and golden whisky bottles could pop and stand out. The grey Flowfast Quartz Structure finish was even applied on the innovative suspended walkway that runs across the top of the distillery’s large tanks.
Areas that are usually just functional spaces have been reimagined into ‘stunning works of art’ in The Macallan’s facility. This is especially true of the barrel room (or cave privee), where the sherry cask maturation of the distilled spirit takes place. This has been turned into a private cellar that displays each cask like a gallery exhibition, putting the visitor in the centre of a semi-circle of back-lit barrels.
303sq m of the self-smoothing epoxy system Peran SL in a glossy black finish was applied to create a sleek floor that would reflect the cellar’s lights and the outlines of the barrels above in a dynamic, eye-catching manner. 745sq m of Isocrete Isopol SBR was installed in this area to produce a reliable and durable polymer modified wearing screed for the Peran SL coating to bond to.
Toby Jeavons, project architect and associate partner at Rogers Stirk Harbour + Partners, said: ‘This acts as a centre piece exhibit and the ‘holy of holies’ for visitors and fans on the Macallan pilgrimage. The design required the ceiling and floor of this space be black in colour and highly reflective so providing the illusion of an endless array of vertical casks. The use of a black coloured Peran SL has again achieved this aim successfully.’
The bonded gravel system Naturewalk was utilised for the distillery’s external perimeter walkway. Naturewalk is a seamless, slip resistant coating designed to reflect the natural beauty of the outdoors. This combination of properties was ideal, as it would tie into the venue’s aesthetics and ensure a safe finish able to survive heavy foot traffic and the inclement Scottish weather.
The site will enable The Macallan to increase production by about a third and thanks to its design and the use of materials that combine aesthetics with practicality, it’s created a working museum to display its traditional craft to visitors in a modern, atmospheric setting.
