Lateral Bellows for Airport Expansion

The London City Airport terminal expansion is being built on a concrete deck supported on over 1000 piles. Between the sections of the deck there can be movement and where critical services pass between sections a fully enclosed expansion joint is required.

Installation
Designing the expansion joints for installation at site into the existing concrete sections was a challenge. FlexEJ designed and supplied installation tooling which allowed the expansion joint to be inserted into the concrete from one side – complete with internal removable pre-extension bars – and then finally seal welded.
