M25 Widening Between Junctions 27 to 30

Location:London

Sector:Infrastructure & Civils

Date:2012

Project Background:One of Europe’s busiest motorways, the M25 handles around 200,000 vehicles every day on its busiest sections. At the core of the UK motorway network, it is one of Europe’s busiest roads and the widening is delivering much needed extra capacity to tackle congestion and improve journey times. In 2002 the London Orbital Multi Model Study (ORBIT) was tasked with addressing the problem. The ORBIT report recommended that most of the dual 3 lane sections of the M25 should be widened to 4 lanes.

Works Completed:Fastglobe Mastics was appointed as a specialist contractor by Skanska Balfour Beatty Joint Venture to carry out the sealing of movement joints as part of the M25 Widening between junctions 27 to 30. Sikaflex Construction, a high performance product, was approved by Skanska Balfour Beatty Joint Venture to be used as a joint sealant on the M25 Widening from junctions 27 to 30. This product has been used to seal the vertical movement joints of the newly constructed reinforced concrete walls at the Emergency Access Routes situated behind the embankment piers. It has also been used to seal the horizontal movement joints of the newly constructed reinforced concrete pier protection and pier strengthening at various bridge locations between junctions 27 and 30 of the M25.
