Qatar: Stirling Lloyd waterproofs Lusail Tunnel
Stirling Lloyd has waterproofed 77,416m<sup>2</sup> of the recently constructed Lusail Tunnel, which forms part of Qatar’s $30bn integrated transportation system
Stirling Lloyd was selected by Lusail Real Estate Development Company (LREDC) to waterproof the recently constructed Lusail Tunnel.
The firm used its Integritank coating to waterproof 77,416m2 of the cut-and-cover tunnel, which forms part of Qatar’s $30bn (QAR109bn) integrated transportation system.
Lusail Tunnel and its troughs, construction of which will begin in spring 2017, will carry both road traffic and light rail.
Commenting on the project, James Hopper, Middle East regional sales manager for Stirling Lloyd, said: “Faced with challenging ground conditions and a fast-track construction process, the ease, speed, and effectiveness of the Integritank fully bonded, seamless waterproofing system was integral to the success of the project.
“For the client, it had also been important to have the reassurance of the system’s efficiency before beginning work. As Stirling Lloyd had already completed several other similar projects in this area, it was a natural decision to choose Integritank when further protecting the investment in the region’s below-ground infrastructure,” he added.
After finding that a number of un-bonded waterproofing systems had leaked on other Lusail sites, LREDC implemented a new set of standards on its projects, according to Stirling Lloyd. The construction of Lusail Tunnel also faced challenging ground conditions and fast-track construction programmes due to an aggressive and high water table, according to the firm.
Stirling Lloyd has supported several previous tunnel projects in the GCC, including Yas Tunnel and Bainuna Street in the UAE.
Once completed, Qatar’s 38km2 Lusail City will accommodate 175,000 people, with 25,000 residential units.
Lusail Tunnel is scheduled to open in spring 2017.
