A low-vibration foundation technique suited to urban and sensitive environments

CFA piles are constructed by drilling with a continuous auger and placing concrete during withdrawal to form a cast-in-place foundation element. This controlled installation process minimizes noise and vibration, making CFA piles well suited to urban sites, sensitive surroundings, and projects requiring efficient and consistent installation.

Key advantages of Continuous Flight Auger (CFA) Piles

Low Noise and Vibration

CFA piles are installed by drilling rather than driving, which significantly reduces noise and vibration, making them ideal for urban areas and sensitive sites.

Efficient and Controlled Installation

Concrete is placed during auger withdrawal, enabling high production rates and consistent pile quality while maintaining control over the installation process.

Reliable Performance in Variable Soils

CFA piles perform well in a wide range of soil conditions and are well suited to projects requiring predictable load capacity and settlement control.

Applications

Continuous Flight Auger (CFA) Piles are commonly used across commercial, residential, and infrastructure projects where construction efficiency, controlled installation, and minimal disturbance are key considerations.

Building Foundations

Used for deep foundations in residential, commercial, and mixed-use developments, particularly in urban environments.

Urban & Sensitive Sites

Well suited to construction near existing buildings, utilities, or infrastructure where vibration, noise, and ground movement must be carefully managed.

Infrastructure & Industrial Projects

Applied to infrastructure and industrial facilities requiring efficient foundation installation and reliable load performance in variable ground conditions.
