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.

Application

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.
