The JSR team were called in to assist the existing civils team, and began work on the project by installing a gas membrane, working closely alongside a structural engineer in order to modify the slab to improve the design effectiveness.
The cast concrete slab was laid in just one day, with the team laying 150 sheets of A252 reinforced mesh ahead of the concrete placement. The 175mm thick concrete slab was laid with a perimeter isolation joint installed to isolate the slab from the steel structure.
To ensure an accurate and level surface was achieved, once the concrete had been pumped in, JSR used a Ligchine Laser Screed machine. Following this, power floating was carried out to leave a smooth, hard surface.
Finally, a surface curing agent was applied to help retain moisture in the curing process, and contraction joints were cut on a 6m gridline.
The project saw JSR deliver a quality job, on time and to budget.
