Gallaher, an English Tabaco producer, bought 31.000 m2 land which has a Tabaco processing factory with two floors and a single-floor Tabaco warehouse from Altab Tütün Ticaret AŞ company from Izmir and the current buildings were subject to renovations for new investments about 30 million Euro. Within the scope of project, we undertook the manufacturing of roof coatings and taking rainwater down by creating special details since that water insulation is extremely important for Tabaco processing and Tabaco production. The project was successfully delivered by providing connections of several insulation materials and conjunction with technical systems special for the project.
