HS2 Euston Station

Keltbray delivered the specialist piling and groundworks package for the Maria Fidelis development, supporting the HS2 Euston programme through the construction of a welfare facility and Construction Skills Centre.

The project marked the first full-scale deployment of Keltbray's proprietary HIPER® pile technology, incorporating hollow, impressed, precast and energy-generating foundation solutions within a single scheme. A total of 40 HIPER® piles were installed to support the piled raft foundation while protecting sensitive underground services beneath the site.

Working within a constrained urban environment, Keltbray combined innovative foundation engineering with integrated thermal pile technology to create a lower-carbon foundation solution that improved structural performance while significantly reducing material consumption.

Key Facts 

• First full-scale deployment of HIPER® technology:
  The project marked the first live implementation of Keltbray's proprietary HIPER® piling system, incorporating all elements of the technology including hollow, impressed, precast and energy-generating piles.
• Significant carbon and material savings:
  The HIPER® solution reduced concrete consumption by 41% and delivered a 35% reduction in embodied carbon compared with the original foundation design, demonstrating the potential for more sustainable foundation engineering.
• Integrated structural and thermal foundations:
  All 40 piles were designed to operate as thermal heat exchangers, supporting a ground source heat pump system and combining foundation and energy infrastructure within a single engineering solution.
