Driven piling may finally be getting the status it deserves! Business Reporter and The Telegraph recently communicated the advantages of the driven piling construction technique.
As UK based piling contractors, Dart & Co Foundations is equipped to provide insight on the matter and reveal our expertise on the subject. Here, we explain exactly how a range of piling techniques benefit the infrastructure of construction in mainland Europe.
Driven piles are installed using vibration or impact hammers to a certain design depth or resistance. The government is committed to identifying the benefits of economic growth and stability of this service following Brexit. UK construction must now start reaping the benefits of precast driven piling and adapt to the change.
Driven piling is widely used in mainland Europe on a range of projects, yet the UK currently shows little energy for this particular method. We specialise in piling and understand the growing need for various types of construction in the UK – existing techniques must be broadened.
Below is a comprehensive guide to driven piles and where they are most useful.
What are driven piles?
A pile is a vertical element of a deep foundation that is drilled deep into the ground. Driven pile installation (also known as displacement piles) provide ground support for structures. There are various types of driven piles and the finished foundation is installed to resist compressive, uplift and lateral loads. Driven piles transfer the load to layers of rock or soil depending on the suitable characteristics of the building.

Common uses of driven piles
- Structural support
- Earth retention
The benefits of driven piling
Driven piles are favoured because the soil displaced by driving the piles into the ground compresses the surrounding soil. This results in higher friction against the side of the piles, thereby increasing the load-bearing capacity. Main advantages include:
- Cost effective
- High quality
Types of driven piles
Installed in either wood, reinforced concrete or steel, piles are available in many shapes and sizes according to the nature of the foundation. Research projects support the advantages of driven piling, as well as precast piling techniques as an alternative.
Driven piles are a complete engineering solution and are provided as a preformed material with fixed shape that is installed by hammering or pushing into the earth.
A range of steel can be used for pile installation – the most common uses are tubes, H piles (universal columns) and rectangular hollow sections.
Precast concrete piles
Precast concrete piles are suitable for a wide range of ground conditions and are typically more beneficial than other piling systems as there is no spoil to dispose of once the operation is complete. Additionally, they are of higher strength, allowing smaller piles to be built into the earth.
Timber piles are generally used within marine environments and low-loaded structures with a 30+ year lifespan. The benefits of timber piles include the low cost, sustainable materials and carbon sequestration.
Composite piles are those made of two different materials and are driven over one another, enabling them to act together to perform a function within a single pile. With good qualities from both materials, these sorts of piles mean great corrosion resistance.
