Project Background

For the first time since 1948, London will be playing host to the Olympic Games in 2012.

Costing in the region of £496m to build, the Olympic Stadium is on a peninsula, with waterways on three sides. Construction officially started on 22 May 2008. A 20m-high “wrap” will encircle the 900m circumference, decorated with historical sporting champions, participating countries’ flags and sponsor logos.

The 80,000-seat stadium is expected to be converted into a 25,000 capacity venue after the Games.


  • Expansion joints in main stadium:
  • Expansion joint widths range from 50mm to 70mm.
  • Depth 15mm to 30mm deep. Back seal Fireseal 400 to give the fire rating.
  • Top seal Hybriflex SMP to give a tougher seal for extra protection but still giving 25% plus or minus movement accommodation.
  • On completion of the joints a movement plate will be placed over the top of the joint as joints of this size can not take foot traffic.
  • There are 1100mtrs of expansion joint to fill totalling 2200mtrs all together.
