Bored piles - Designing Buildings Wiki

Introduction . Bored piles, also known as replacement piles, are a commonly-used form of building foundation that provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.. Bored piles are piles where the removal of spoil forms a hole for a reinforced concrete pile which is poured in situ.
