About the Technology:
CFA (Continuous Flight Auger) technology is a modern method of installing bored piles without soil excavation, providing high load-bearing capacity and minimal environmental impact. This method combines drilling, concreting, and reinforcement in a single continuous process, making it one of the most efficient solutions for creating deep foundations on various soil types.
- Preparation and Layout — precise determination of pile locations according to the project.
- Continuous Drilling — lowering the auger (hollow helical stem) to the design depth.
- Concrete Supply — injecting concrete mix under pressure through the hollow auger.
- Reinforcement Installation — placing the reinforcement cage into the freshly placed concrete.
- Pile Head Formation — final works on arranging the upper part of the pile.
Key Features and Advantages of CFA Technology
-
Speed and Quietness
The continuous cycle of drilling and concreting eliminates downtime, and the low noise level allows work in confined urban conditions near existing buildings.
-
Borehole Stability
The auger serves as temporary support, preventing borehole walls from collapsing even in water-saturated and loose soils, thus eliminating the need for casing pipes.
-
Reinforcement
The ability to place reinforcement cages into fresh concrete to full depth ensures high pile load-bearing capacity and reliable bonding of materials.
-
Drilling Parameter Control
Onboard electronics precisely control verticality and concrete volume, guaranteeing void-free filling and improving soil adhesion through pressure.
-
Versatility of Application
The method is effective in a wide range of soils (including high groundwater levels) and allows piles of various diameters and depths for any type of facility.

Prices
The cost of installing CFA bored piles is determined by project parameters and construction site conditions. The price is influenced by the diameter and depth of piles, the volume of the pile field, soil characteristics, reinforcement requirements, and equipment access conditions. To calculate the cost, data from engineering-geological surveys, a pile field project, or initial pile parameters, estimated foundation loads, and information about the construction site are required.

-
Is CFA technology suitable for urban development?
Yes. The method is characterized by low vibration levels and can be used near existing buildings and utility networks.
-
Can work be performed on weak soils?
Yes. The technology allows piles to be installed in a wide range of soils, including water-saturated and weak foundations.
-
Is a completed pile field project required?
It is desirable, but if geology and loads are available, we can prepare a technical solution and preliminary pile parameters.
-
How is pile quality controlled?
Control is carried out based on drilling and concreting parameters, as well as the volume of concrete supplied and the depth of pile installation.
