Frequently Asked Questions
What is CFA Piling?
CFA (Continuous Flight Auger) piling is a foundation technique where concrete is pumped through a hollow auger as it is withdrawn from the ground, creating a strong and continuous pile without leaving the borehole open.
Where is CFA piling commonly used?
CFA piles are used in residential, commercial, and industrial projects, especially where surrounding structures need low vibration and minimal noise during construction.
Is CFA piling suitable for all soil types?
CFA piles work best in soft clay, sand, loose to medium soils, and mixed ground conditions. Extremely hard rock may require alternative piling methods.
How deep can CFA piles go?
Typically, CFA piles can reach depths of up to 30 meters, depending on project requirements, soil conditions, and equipment capacity.
