Piling Methods

What are the different piling methods?

A range of piling methods can be used to create strong foundations by reaching deep, stable layers of ground. This is important when topsoil is too weak to support a structure. The best method of piling will depend on the type of ground, the weight of the foundations required, and the level of space and access available. Each method has its benefits and is suited to different situations.

Driven Piling – Solid piles are driven into the ground using impact, delivering a high load capacity. This method is efficient across a range of soil types.
Screw Piling – Steel piles with helical plates are screwed into place, creating minimal soil disturbance and allowing for fast installation in confined areas.
Augered Piling – Flight augers drill into the ground before concrete is pumped in, while the auger is withdrawn. This reduces noise pollution and vibration.
Vibro Piling – Piles are inserted through the use of controlled vibration, reducing noise pollution and soil displacement in sensitive locations.

By selecting the right method of piling, engineers are able to create strong, long-lasting foundations that meet structural requirements and minimise the impact on the environment.

Pile Installation Methods

Explore key pile installation methods, each offering unique advantages to suit varied ground conditions, constraints and structural requirements.

Driven Piling

Driven piling is a widely used method, chosen for its reliability, installation speeds and project suitability. The process involves forcing pre-formed piles made from concrete, steel, or rarely, timber, into the ground by using impact. These piles are available in a range of forms, including H-section piles for penetrating dense layers. Driven piling performs best where the pile can displace and compact the surrounding material to increase load-bearing capacity, such as sands, gravels and firm clays. Benefits include being able to carry loads as soon as installation is complete, dependable quality and efficiency. This method is a popular choice for commercial buildings, bridges and more.

Screw Piling

Screw piling is a fast, efficient method of laying foundations. Using steel piles with spiral plates welded to the shaft, these piles are rotated or screwed into the ground using hydraulic machinery. Screw piling performs well across a range of soils, including clays, sands and mixed ground, and can be used in areas with restricted access or near existing buildings. This method offers minimal soil disturbance, low vibrations and noise, and it can bear loads immediately once installed. Screw piling is favoured for its speed, versatility, and lower environmental impacts, making it a great choice for both permanent and temporary structures like residential buildings, elevated walkways, festival stages and retail units.

Augered Piling

Augered piling is a low-noise and low-vibration method that uses a continuous flight auger (CFA) or a sectional flight auger (SFA) to drill into the ground before filling the hole with concrete as the auger is withdrawn. This method allows reinforcement to be added to the wet concrete to create a strong, cast-in-place pile. CFAs are designed for areas where larger rigs can operate, while SFAs are ideal for tight urban spaces or inside existing buildings. Augered piling is a strong choice in clays, silts and mixed ground condition and is known for offering precise control and suitability across a range of sites. Widely used for residential and commercial projects, this method can also be used in infrastructure projects such as utility installations or port and harbour works.

Vibro Piling

Vibro piling uses controlled vibration to insert, or compact piles, into the ground with minimal noise and disturbance to surrounding areas. Useful in built-up areas or sensitive locations where impact-driven piling may be too disruptive, this piling method is known for faster installation, low environmental impact and improved ground conditions. Vibro piling is commonly used in infrastructure projects like embankments, residential developments and commercial buildings.
