CFA Piling & Auger Equipment

At Delta Concrete Products, our CFA piling and auger equipment is engineered to deliver dependable, high-performance foundations with minimal environmental disruption. The process uses a hollow auger to drill into the ground while concrete is pumped through the centre as it’s withdrawn, forming strong, continuous piles without the need for casing. This controlled, vibration-free approach makes it ideal for projects in built-up or sensitive areas. Because CFA operations depend on consistent, high-pressure concrete flow, durable components such as concrete steel pipes, pipe elbows, and clamps are essential for reliable performance and long service life on demanding sites. 

Features of Our CFA Piling & Auger Equipment 

Built for performance and precision, Delta’s CFA piling equipment combines robust materials with practical engineering. Each feature is designed to keep projects running safely and efficiently on demanding construction sites. 

  • Hollow-stem auger allows drilling and concreting in a single process, reducing installation time and improving pile quality. 

  • High-pressure pipelines and concrete connecting systems deliver smooth concrete flow from the pump to the auger, minimising blockages. 

  • Hardened elbows and pressure-rated clamps prevent leaks and wear during continuous operation. 

  • Modular coupling design offers fast setup and easy adjustment for varying pile depths. 

  • Integrated monitoring sensors provide live readings of flow, pressure, and torque for precise control throughout each pour. 

Benefits of Using CFA Piling Equipment 

Using Delta’s CFA piling equipment helps contractors achieve reliable results with less waste and lower maintenance demands. It’s an efficient, low-impact solution for deep foundation work in both commercial and infrastructure projects. 

  • Continuous pile formation creates a solid foundation with fewer weak points or air gaps. 

  • Low vibration and noise output make it suitable for built-up or sensitive environments. 

  • Reduced spoil generation helps cut disposal costs and supports sustainable site management. 

  • Abrasion-resistant components extend service life, reducing downtime and repair needs. 

  • Fast installation speeds improve productivity, especially when used with concrete formwork systems and other foundation equipment. 

Why Choose Delta CFA Piling & Auger Equipment 

Delta’s CFA systems are designed for real-world reliability and long-term performance. Every component, from the auger assembly to the pipe supports for concrete pumps, is built to withstand the rigours of continuous concrete delivery under pressure. Our systems provide consistent output, high accuracy, and the flexibility to adapt to different soil conditions or pile lengths. This combination of quality and versatility helps contractors complete projects efficiently while maintaining safety and performance standards. 

Environmental & Regulatory Compliance 

CFA piling offers a cleaner, lower-impact alternative to driven or bored piling systems, reducing waste and protecting nearby structures. Because the process produces minimal spoil and vibration, it’s ideal for environmentally sensitive sites and urban construction. Using sealed pipelines and flexible hoses helps prevent leaks and contamination, ensuring responsible handling of concrete wash water. Delta Concrete’s focus on durability and containment supports environmentally conscious building practices and aligns with industry expectations for site safety and sustainability.

CFA Piling FAQs

  • CFA piling combines drilling and concreting in a single continuous operation, forming strong, vibration-free piles. It’s used for deep foundations in projects where speed, accuracy, and minimal disruption are required, such as commercial builds or infrastructure work.

  • We supply hollow augers, abrasion-resistant pipelines, elbows, pressure clamps, and monitoring systems built for high-demand concrete flow conditions. Each component is designed to integrate seamlessly with existing CFA rigs for reliable, consistent performance on site.

  • It performs well in sands, gravels, clays, and mixed soils where borehole stability and low vibration are essential. The method is particularly effective in urban or confined areas where other piling techniques may cause excessive disruption.

  • CFA piling may not be ideal for very hard rock or extreme depths requiring heavy casing or specialist equipment. However, with proper site investigation and planning, it remains a highly adaptable option for most ground types.

  • It minimises spoil, vibration, and noise, making it ideal for sensitive or urban environments. By reducing waste removal and avoiding dewatering, it also lowers carbon emissions and improves overall site sustainability. 

  • After concrete is pumped through the auger, the auger is withdrawn and reinforcement cages are placed into the fresh concrete to form a strong structural core. This ensures excellent bond strength and consistent pile integrity from top to base.
