Rydon sets record breaking concrete pour

Rydon has set a new record within the company for the largest ever concrete pour, delivering a volume of approximately 450 cubic metres within a single sitting.

The achievement was reached at the redevelopment of the Queen Elizabeth Hospital on Hackney Road in Tower Hamlets, and involved 60 concrete deliveries with a delivery every 10 minutes for the whole 10 hour day.

Such a large pour was required deliver a raft foundation for one of the new blocks, around a metre in thickness. This part of the development site is located above a sewer, which runs underneath the site, and meant that the team could not use the piling foundation technique deployed elsewhere on the project.

Whilst a new record for Rydon, it is still some way from the UK record for a slab pour, which currently stands at 3,200 cubic metres in the UK at the One Blackfriars site in central London. But it still represents a remarkable effort from all of the team involved to ensure this enormous task, including all of the logistical planning, was executed successfully.

The site team will shortly conclude foundation works at and below ground level over the coming weeks. We will then continue our focus on the concrete structures, rapidly emerging from the ground and already reaching the fifth floor in some places.

In other numbers, the construction of the project will require a total of 8,000 cubic metres of concrete. At 2.4 tons per cubic metre this equates to almost 20,000 tons, equivalent to the weight of around 14,000 family cars.

Rydon’s redevelopment of 188 new homes at the former Queen Elizabeth Hospital is being delivered with Family Mosaic and will provide 38% affordable homes (43% by habitable room), for rent or for purchase through shared ownership. The remainder have been fully sold by Rydon through Mettle&Poise.
