From Linear to Circular Cconomy; Using Hollow Piles to Reduce Embodied Carbon and Promote Pile ReuseÂ-Video

Video Transcription

Video Summary

Asha of Kelpbrae and Andrew of City, University of London present the HyperPile, a hollow, impressioned precast foundation designed to make pile reuse more practical and sustainable. Existing piles often clash with new foundations, while removal is costly and reuse is limited by uncertainty about their condition and capacity. HyperPile’s design uses concrete more efficiently and increases ground capacity through impressions along the shaft. Its hollow core allows inspection, sampling and testing, helping engineers decide whether piles can be reused—or extended if needed. A London project using HyperPiles for both building support and energy generation reduced construction and operational carbon emissions.
