World Heritage Zollverein Shaft XII, Coal Washing Plant, Essen
Zeche Zollverein is a colliery which was closed in 1986. On 14 December 2001, Zeche Zollverein was officially designated as a World Heritage site by UNESCO. Nowadays, the complex is a centre for creative industries and the international design industry, also offering a wide-ranging cultural programme. An event of considerable symbolic importance for Zollverein as a World Heritage site was the conversion of the former coal washing plant, the largest building in the complex. After three years of work, the converted plant was re-opened in August 2006. The plant now houses the visitor centre for Zollverein and the Route of Industrial Heritage and will also be the home of the Ruhr Museum from 2008 onwards. In addition, an exhibition hall offering outstanding views of the Ruhr region has been created under the roof of the building. For the conversion of the existing building and especially the construction of the new roof, the client opted for high-grade products and professional workmanship. The roof consists of trapezoidal sheet sections with additional armoured Aquapanel boards, in some cases installed almost vertically. The objective was to waterproof the roof without any visible seams or joints. It was decided to use a system that would reliably meet all these requirements on a long-term basis: the CONIROOF 2103 roof waterproofing system from BASF.
