VIP-Polymers Ltd. has won contracts to provide tunnel seg- ment gaskets for two major tunneling projects, one in the United Kingdom and one in India. The global specialist rubber seals and gasket manufacturer has been commissioned to supply its latest cast-in gasket for the 12.7- km Thames Tideway Central wastewater tunnel in London. VIP, based in Huntingdon, Cambridgeshire, U.K., has also won a contract to supply tunnel segment gaskets for a project to extend um o. tthew Levitt, VIP Technical Business Dev - er, said: "Our success with both projects demonstrates our ability to deliver a wide range of innovative products and technologies for supporting major water and transport infrastructure projects anywhere in the world. "These are exciting tunneling projects that are vital to the sus- tainable development and growth of two great cities, and we're delighted to be involved with them." Thames Tideway Central is the longest of three sections of a 25 km tunnel, due for completion in 2024, designed to prevent the discharge of untreated storm water and sewerage from 34 com- bined sewer overflows into the tidal River Thames. VIP is supplying its cast-in gasket referenced VIP028CI with patented corners to tunnel segment pre-caster Pacacar for the sec- tion, which will be 12.7 km long, with an inner diameter of 7.8 m. Supply commenced in December 2017. A consortium made up of Ferrovial Agroman and Laing O'Rourke (FLO JV) is the main contractor for the central section, which runs from Fulham to Blackfriars and will have 6,100 tun- nel segment ring sets. VIP's compliant compressible corner technology for cast-in gaskets delivers consistent load performance along the entire pe- rimeter of the gasket. This eliminates the risk of high loads at one or more of the gasket's corners during installation, which could contribute to segment cracking. The technology has already been proven on other tunneling projects, including the 5 km Shieldhall wastewater tunnel in Glasgow, commissioned by Scottish Water. VIP has been commissioned by J Kumar Infraproj- ects to supply tunnel segment gaskets f umbai o Line 3 (Packages 5 and 6) tunnel, which is being built f um o Rail Corp., a joint venture between the Indian Government and the Government ashtra. The project involves the construction of a 4.5 km twin tunnel, with an outside diameter of 6.6 m, requir- ing a total of 17,800 tunnel segment ring sets. Production of the glued-in gaskets selected for the tunnel has already begun at VIP's factory in Hunting- don. This latest contract continues VIP's long-standing position as a major supplier of TSGs in India, having previously supplied four phases of the Delhi o project and the Ghatkopar High Level T um- bai. Levitt said: "The gasket has been specifically devel- oped as a modification of our VIP024 gasket to provide additional sealing assurance sought by project engi- neers as the tunnel pass er."
