Overview

The Hiperpile is a suite of innovative solutions developed by Keltbray which can combine to deliver significant sustainability benefits and the ability to harness the grounds geothermal energy within the building foundations themselves.

The Hiperpile comprises a hollow void which is constructed through the use of “stacked” precast units, thus reducing the material volume and embodied carbon required to construct piled foundations. The central void is then utilised as a geothermal exchange mechanism, providing the building with highly efficient heating and cooling.

The heating and cooling potential of the Hiperpile system is not limited to the building or development it is used on but also extends to adjacent plots or heat networks, acting as an additional energy source as well as a large thermal store.

This redefines piled foundations as energy enabled assets which provide significant value to the development and surrounding region and are a step change in the move towards net zero.

Stuart Norman

Stuart Norman is a Chartered Engineer and Fellow of the Institution of Civil Engineers, with more than 25 years’ experience in the piling and foundations industry.

In 2026 he became Chair of the Federation of Piling Specialists and is currently Director of Hiperpile Ltd, where he leads the continued development and commercialisation of Hiper solutions.

In 2019, while managing Keltbray’s piling division, Stuart identified the opportunity to develop a next-generation thermal energy pile.

With support from Innovate UK through the Transforming Construction Challenge, the concept was taken from an initial idea through an extensive programme of laboratory testing, field trials and full-scale development.

Almost seven years later, Hiper has evolved into a combined structural and thermal energy solution, designed to turn foundations into valuable long-term energy infrastructure.

In 2025, the Hiperpile was awarded the ICE London Brunel Medal for low-carbon solutions in the built environment.

Throughout his career, Stuart has been involved in the delivery of major UK infrastructure and building projects, including the Silvertown Tunnel, 8 Bishopsgate, London and the new Tottenham Hotspur Stadium.

He also oversaw the first-ever successful implementation of zero-cement, ultra-low-carbon concrete in permanent works foundations at Canada Water, London.

His career has been shaped by a belief that engineering innovation is not simply about having good ideas, but having the resilience, teamwork and determination required to turn them into reality.
