Construction Specialties’ (C/S) Allway® Expansion Joint Covers have
been installed at the new Aviva Stadium in Dublin, the 50,000
capacity venue built on the original Lansdowne Road Stadium site.
The original sporting venue was demolished to make way for the brand
new multi-purpose event stadium. C/S Expansion Joint Covers were
specified for the new stadium to accommodate the movement of the
building (thermal and wind sway) without compromising its structural
integrity. The installation was completed by the company’s in-house
installation team, Conspec Contracts.
Sean Stagg, Contracts Manager at John Sisk & Son Ltd, said: “The
type of building and its purpose as an entertainment venue means
that the expansion joint covers had to meet high performance
requirements and be suitably fire resistant. This was a technically
demanding project, but the C/S Technical Department were able to
address the unique challenges and develop a bespoke solution.
“C/S recommended Expansion Joint Covers for the project and their
Conspec Contracts team installed the system, which was a real
advantage, as we knew we could rely on skilled installers with an
excellent knowledge of the product and its capabilities.”
Internal levels of the building were fitted with the AL-200HD
system, a heavy duty aluminium floor-to-floor cover for 50mm wide
expansion joints. A moisture barrier and drainage system were
installed underneath the expansion joint covers on the new access
podium over the railway line which allows spectators to access the
stadium at premium seat level. Floor to wall versions of the L-200HD
system were also used in other areas.
This high performance joint cover system can accommodate as much as
100mm of overall horizontal movement, significantly more than the
65mm required for the project.
The C/S AL-200HD joint covers are designed to withstand heavy duty
rolling loads and when combined with C/S moisture barriers, are
resistant to water ingress. The specification in internal areas of
the stadium also included C/S Reflex Fire Barrier and SM-200N wall
joint covers. The fire barrier is an insulation layer that provides
a minimum of two hours integrity in a fire, ensuring the complete
solution met the requirements for fire resistance.
