Art gets proper housing
The renovation of a complicated roof and the maintaining of the original design represented a tough re-waterproofing project. The cold applied, liquid membrane A Decothane Delta 25 system offered the ideal solution.
Oldest gallery of the Tate network
Tate Britain is a renowned art gallery and part of the British Tate gallery network. Located in the Tate’s original premises on Millbank, London on the site of Millbank Prison, it is the oldest gallery in the network, dating from 1897. It is visited by around 1.5 million people every year. Tate holds the national collection of British art from 1500 to the present day as well as international modern and contemporary art.
International first-class art
The collection embraces all media, from painting, drawing, sculpture and prints to photography, video and film, installation and performance. The galleries seek to portray significant developments across all areas of fine art with works of outstanding quality and importance. British art is represented by artists chosen for their contribution to its history and development, rather than their nationality alone. While it has traditionally focused on art from Western Europe and North America, Tate has recently expanded its holdings with modern and contemporary artworks from Latin America, South-East Asia and Eastern Europe.
Re-waterproofing the roof
A large-scale renovation was recently carried out on the museum building. This sought to do justice to its architectural style while also enhancing its advantages. The front part of the building has a classical portico and dome behind, including a lead rotunda roof which had fissured and split over the years. This 600m2 roof presented a very complex re-waterproofing challenge due to the difficult details over the existing lead rolls, and required the installation of a product that was heat tolerant and able to deal with high levels of movement whilst maintaining the waterproof integrity.
Complications made simple and aesthetics kept original
The Solution A Decothane Delta 25 system from Sika Liquid Plastics was specified for the project. This is a cold applied, liquid membrane that cures to provide guaranteed waterproof protection. The membrane is seamless membrane that can be installed quickly and easily even around complex detail areas, making it ideal for use on complicated roofs. Once installed, it meets the highest fire ratings available for a roof system. The color used is also very similar to that of lead, and because it was applied over the existing lead work the finished aesthetics are very similar to those of the original roof.
