Advantages of CFA piling
Piles are constructed by drilling with a long continuous auger to the designed depth. Concrete is then pumped through the hollow stem of the auger during its extraction. Steel reinforcement is then plunged directly into the wet concrete.
Introduced to the UK by Cementation in the early 1980’s, the technique allows construction of piles in granular soils and below groundwater level, without the need for temporary casing. Production is generally quicker than for rotary bored piling and involves very little vibration.
Cementation Skanska has a range of dedicated and multidisciplinary rigs of various sizes, capable of installing CFA piles for a multitude of applications. All are fully computerised and equipped with the technology necessary to provide a fully quality-assured piling solution.
