Expanded / Flared Pile Heads
Integral enlarged pile heads when installing CFA piles provide an economic solution for floor slabs, raft foundations and areas of hardstanding.
The enlarged pile head is formed during the pile construction process by the piling contractor and is integral to the pile. This process eliminates the need for pile trimming resulting in further cost savings.
We provide circular piles heads with diameter between 450mm up to 900mm. The enlarged pile head is fully reinforced and can be constructed with projecting reinforcement bars or the reinforcement can be left below the pile head.
Expanded pile heads reduce punching shear forces which results in a reduced slab thickness providing overall construction cost savings.
