After applying MAPELASTIC FOUNDATION, either MAPECOAT I 24 or MAPECOAT DW 25 were used for the protection of the waterproofing layers during their service life. MAPECOAT I 24 two-component epoxy paint has a high resistance to aggressive chemical agents. MAPECOAT DW 25 is a two-component epoxy paint used to form a coating on concrete surfaces that are in contact with drinking water and foodstuffs.
MAPEPROOF SWELL single component hydro-expansive paste was used to solve the delicate problem of waterproofing pipe inlets and outlets. MAPEPROOF SWELL has been specially developed to form flexible, waterproof seals in cracked reinforced concrete or in precast elements with infiltration of water.
THE AIR TRAFFIC CONTROL TOWER
The site’s landmark air traffic control tower has been designed by Pininfarina and Aecom, selected from six solutions proposed by international architecture studios, including Zaha Hadid, Fuksas, Moshe Safdie, Grimshaw Architects and RMJM.
The project has won the prestigious International Architecture Award 2016, promoted by the Chicago Athenaeum: The Museum of Architecture and Design and the European Center for Architecture, Art Design and Urban Studies.
The design concept of the tower features elements evocative of Turkish culture and is inspired by the tulip, which has been a symbol of Istanbul for many centuries and an important cultural reference in Turkish history. The shapes of the flower were redesigned and reinterpreted through Pininfarina’s identity, based on its profound knowledge in automotive design and wind tunnel modelling, as well as on the influence inherited from aerodynamic shapes used in aeronautical design.
AQUAFLEX ROOF PREMIUM ready-to-use, water-based polyurethane waterproofing membrane was used for waterproofing several surfaces in the ATC tower as it was the best solution for both old and new surfaces with slopes or irregularities.
MAPECOAT I 600 W two-component transparent epoxy primer in water dispersion was used on the surfaces as an adhesion promoter and MAPEFLEX PU 40 polyurethane sealant with a low modulus of elasticity was chosen for sealing expansion and contraction joints.
KERACOLOR FF high performance, polymer-modified, water-repellent, cementitious mortar was used for grouting joints in all the ceramic tile coverings of the project. ELASTORAPID ,high-performance, two-component, highly deformable, cementitious adhesive with extended open time, was used for bonding ceramic tiles in some piers.
WATERPROOFING THE TERRACES
For waterproofing the green terraces which cover about 75,000 m2 in the departures area, PURTOP 400 M two-component, solvent-free, spray applied, hybrid polyurea membrane was the selected product. It has an excellent resistance to alkalis and diluted acids and an elongation capacity higher than 400%. Besides, it can boast the certification for resistance to root penetration according to CEN/TS 14416 which was mandatory for green terrace application in this project. Before using PURTOP 400 M, PRIMER SN two-component fillerized epoxy primer was applied on the substrates.
MAPEFLOOR FINISH 55 highly flexible polyurethane finish was finally used as a protective layer for a 2000 m2 area where colour protection was needed.
