Eliminator® protects the world’s longest combined motorway and railway bridge.



Project Overview

Built in the north of Istanbul - Turkey between 2013-2016, the Yavuz Sultan Selim Bridge, or ‘Bosphorus 3’, as it is often called is part of the projected 260km long Northern Marmara highway. Once complete, the highway will bypass urban areas of Istanbul in the north connecting Kınalı, Silivri in the west and Paşaköy, Hendek in the east.

This suspension cable bridge is designed for both rail and cars. It is the longest combined motorway / railway bridge in the world and is the eighth longest suspension bridge.

Aside from its sheer length and size, the bridge is equally significant for its powerful logistical positioning: when it is finished, the new rail system running over the bridge will include Marmaray and Istanbul Metro connecting Asia and Europe, Ataturk Airport, Sabiha Gokcen Airport and the third airport set to be opened in 2018. This is important, not only for Turkey, but for the rest of the world, as it will be part of a ‘New Silk Road’ linking China and Europe by rail.

Product Selection

Over the past fifteen years, the state highways agency, KGM, has specified Stirling Lloyd’s Eliminator system for several successful high profile collaborations in Turkey. Such celebrated schemes include the Osman Gazi Bridge, Fatih Sultan Mehmet Bridge, Bosphorus Bridge and Haliç Bridges. As a result, it was the obvious choice for KGM to select the Eliminator system for this project, too.

For work of this scale and size, it was essential that the bridge deck waterproofing would not only provide proven long lasting protection, but also allow quick and easy application. Stirling Lloyd’s Eliminator system addressed both of these objectives.

The coating process began on 28th March 2016 and was completed on 24th April 2016, in time for the bridge’s inauguration ceremony on 26th August 2016. In total, the Eliminator system was used to cover 37,435m2.  


For this project, there were two separate areas to which the Eliminator system needed to be applied: the main orthotropic steel bridge deck and the walkways.

There were two elements to the waterproofing process: the preparation, directly followed by the application of the waterproofing system itself. Firstly the steel bridge deck was prepared by shot blasting using metallic grit. An inspection by Stirling Lloyd’s Technical Team confirmed that the preparation had provided the Sa 2.5 Standard specified. This was followed by the cold, spray application of the Eliminator system, the speed of which was paramount to meet the tight deadline on the project.

The authorised contractors, ICA, were able to apply 1500m2 on average of the bridge waterproofing system per day, enabling quick contract progression. This was facilitated by the fact that each element of the Eliminator system cures in under an hour, allowing the next element to be applied immediately afterwards.

Positive Results

Daghan Erel, Regional Sales Manager at Stirling Lloyd Polychem, for Turkey and Central Asia comments: “The Yavuz Selim Sultan Bridge is an extremely important, high profile project. The bridge will play a key role in international trade for many years to come, so we were pleased to have been chosen to provide the protection. As well as being a major element of the new rail system that will connect Europe and Asia, highway traffic on the existing Bosphorus bridges will also be significantly reduced as a result of this construction.

“Given all the hard work and time that has gone into constructing the bridge, there was added pressure to ensure the Eliminator was applied effectively to optimise protection of the bridge for years to come. We had a skilled team of workers on board to make sure this objective was met. With an impressive track record on major projects across the world, we are confident that our product will stand the test of time, reducing future maintenance costs and the inherent disruption."


Based on their positive experiences in the past, KGM turned to the Eliminator system to provide the long-lasting protection that this high profile structure required. The system’s ease and speed of application, rapid curing, toughness, durability and ability to withstand difficult site conditions meant that the strict project programme was maintained, while these physical attributes of the system will in turn help to minimise long-term maintenance costs and extend the service life of the bridge.
