Steel Bearing Pile Foundations

With their superior strength, durability, and versatility, steel-bearing pile foundations provide support for your development that will stand the test of time. They’re a type of deep foundation system used to support developments at sites where the soil is soft and unstable and too weak to support the weight of the building. Steel-bearing pile foundations consist of steel columns, or piles, that are driven deep into the ground to support the weight of the structure above.

Whether you're building a small residential home or a large commercial complex, steel-bearing pile foundations can be customised to fit your specific needs and site conditions, ensuring a reliable foundation solution that will stand up to even the toughest environmental challenges.

Driven Piling Solutions - Steel CHS options

Steel circular hollow section (CHS) piling is a popular choice for driven piling solutions due to its high strength and durability. The circular shape of the piles distributes the weight of the structure evenly, providing a stable and reliable foundation. Steel CHS piling is also highly resistant to corrosion, making it a low-maintenance option that will stand up to even the toughest environmental conditions.

Driven piling solutions are an effective way to provide a solid and stable foundation for buildings and other structures. One of the key advantages of steel CHS-driven piling solutions is their versatility. We can use them in a wide range of soil conditions and customise them to fit the specific needs of your project. Steel CHS piles can be cut to any required length, making them a very functional solution for a variety of construction projects.

Screw Piling Solutions
(Helical Screw Pile)

Screw piling solutions, also known as helical screw piles, are low-impact foundation systems and can be used in environmentally sensitive areas without causing damage to the ecosystem.

Screw piles create a strong and stable base in a variety of soil types, including soft, wet, and unstable ground.  The helical shape of the plates creates a strong grip on the surrounding soil, making screw piling solutions an ideal choice for projects where traditional foundation systems may not be suitable. We install screw piles by screwing them into the ground using specialised machinery.

One of the key characteristics of screw piling solutions is their adaptability. They can be customised to fit the specific needs of your project, including the weight and load of the building or structure and the soil conditions at the construction site. They can also be easily installed and removed, making them an ideal choice for temporary or relocatable structures.

Our Process

Pile design &

Following our unique pile design and development process is essential to ensuring the safety and stability of buildings and other structures. The expertise of our engineers and installers, combined with cutting-edge technology, allows us to gather data and design the anchoring solution capable of supporting the heaviest loads in the most complicated environmental challenges.

Pile foundation construction on the building site

01 Site evaluation

Site evaluation is the first step in the pile design and construction process. Assessment  involves gathering information about the site, including soil conditions, the surrounding environment, and any other factors that may impact the design and construction of the piles. We use gathered data to determine the best type of pile for the project, as well as the size and spacing of the piles.

02 Soil testing

Soil testing is an essential step in the pile design and construction process. We will take soil samples at the site and analyse them to determine their properties and characteristics. We will then use this information to design the pile system and ensure that the piles can support the structure's weight.

03 Pile design

Pile design is a complex and specialised process that requires a thorough understanding of engineering principles and practices. Our goal is to create a pile system that is potent, stable, and capable of supporting the weight of the structure. We use information gathered in previous phases of the project to select the best materials and design the best solutions for your project.

04 Pile construction

Further ground surveys and construction are the final pile design and construction steps. This involves installing the piles, using techniques and methods designed to ensure accuracy, stability, and safety. The construction process is carried out by our experienced professionals, who are familiar with the latest techniques and best practices in pile construction.

Frequently asked questions

Pile Foundation Design & Construction

01What is a pile foundation?

A pile foundation is a type of deep foundation used to transmit loads from a structure to a deeper and more competent soil layer. The pile foundation consists of columns designed to safely and effectively support the building’s load in the most challenging soil and weather conditions. These columns are typically made of concrete, steel or timber. A pile foundation suits sites with poor soil conditions, high water tables, and deep excavation. They are commonly used in large structures such as bridges, high-rise buildings, and offshore platforms, but also in domestic construction to ensure the durability and longevity of the structure.

02What factors do you consider when designing the pile foundation?

The design of pile foundations requires careful consideration of several factors to ensure that it is safe, reliable, and cost-effective. Our experienced engineers design all our pile foundation projects to assure safety and the highest standard for your project.

Some of the key factors we need to consider while designing pile foundations include:

Load Capacity: Load-bearing capacity is the most crucial factor in the design stages of a pile foundation. Our process starts with determining the type and magnitude of loads that piles will be subjected to, such as vertical, horizontal, and lateral loads. Based on this information and other key site characteristics, our engineers design the pile foundation to support structural loads without failure.

Soil Characteristics: We investigate soil conditions at the site to determine the type of pile foundation that is most appropriate. It includes the soil type, soil strength, and soil stiffness. We determine the soil conditions through thorough laboratory and in-situ tests such as boring, cone penetration (CPT), and dynamic testing.

Pile Types: We offer several pile types, including concrete piles, steel piles and timber piles, followed by appropriate installation. Our pile engineers suggest the best type of pile foundation depending on the load capacity required, the soil conditions, and the cost.

Pile Length: The pile length is another critical factor when designing a pile foundation. The pile must be long enough to reach a competent soil layer but not so long that it becomes uneconomical. Our engineers determine the pile length by evaluating the soil conditions and the loads the foundation will be subjected to.

Pile Spacing: The piles must be designed and placed far enough apart to avoid interference with each other but close enough to provide adequate support for the structure's load. We determine pile spacing by considering the load capacity of the piles and the spacing of the beams or columns in the structure.

Connection Details: The connection details between the pile and the structure are also important when designing a pile foundation. The connection must be strong enough to transfer the loads from the structure to the pile, and it must also be designed to resist corrosion and other environmental factors.

03What are the benefits of pile foundations?

Pile foundations have several benefits, including:

Increased bearing capacity: Pile foundations can transfer loads deeper into the soil, unlike traditional foundations. Hence, they can massively increase the bearing capacity for larger developments as well as smaller domestic projects, increasing their value.

Improved stability: Pile columns are installed into the ground to transmit loads to a lower subsoil level. They are often used in soft or loose soil conditions with low bearing capacity. Also, pile foundations stabilise structures on slopes or areas prone to landslides and soil liquefaction.

Reduced settling: Thanks to their capability to transfer loads deeper into the soil, pile foundations reduce settling compared to shallow foundations.

Sustainability: Pile foundations can be more sustainable and environmentally friendly. Compared to traditional foundations, pile solutions require less concrete. The installation minimises disturbance to the environment and costs of the project.

Versatility: Pile foundations can be used in the most challenging soil conditions and for various structures, from small residential buildings to large bridges and offshore platforms.

04Are pile foundations more sustainable than traditional foundations?

Pile design is a foundation solution that can be more sustainable and environmentally cautious than traditional foundation systems.

During the installation, pile foundations require minor excavation and site preparation compared to traditional solutions. This solution minimises noise disturbance, requires less soil displacement and has less impact on the surrounding landscape. Additionally, pile foundations use significantly less concrete than standard concrete foundations. Concrete production significantly contributes to greenhouse gas emissions, and using less concrete reduces the project's carbon footprint.

We incorporate recycled materials into our pile designs, such as scrap steel, recycled plastic, reclaimed wood, fly ash and recycled concrete. Using recycled materials in pile foundations reduces waste and helps us to promote sustainable construction practices. We ensure that the recycled materials used in foundation systems meet the necessary quality and safety standards.

Choosing a pile foundation solution minimises disturbance to the surrounding environment and provides a long lifespan to your development.

05When should I choose pile foundations?

Pile foundations are suitable for most small domestic or heavy industrial and commercial developments. They are important to consider when the soil conditions at a construction site are unsuitable for traditional shallow foundation systems or when the building or structure is too heavy or tall for a shallow foundation to provide sufficient support.

Here are some common scenarios when pile foundations may be the best choice:

Weak soil: If the soil at the construction site is weak and unable to support the weight of the building or structure, pile foundations are driven deep into the ground to reach more stable soil layers and provide sufficient support.

Lateral loads: Pile foundations can resist lateral loads, such as wind or earthquake forces, more effectively than shallow foundations, making them a good option for tall buildings or structures in areas with high wind or seismic activity.

Heavy loads: Pile foundations can support heavier loads than shallow bases, making them a good option for large industrial buildings or structures with heavy equipment.

Waterlogged or saturated soil: Pile foundations are a great solution in areas with waterlogged or saturated soil. Shallow foundations would be impractical due to the risk of settlement or subsidence.

Environmental sensitivity: Pile foundations can be a good choice for environmentally sensitive areas, as they can minimise the disturbance to the surrounding soil and ecosystem compared to traditional excavation-based foundation systems.

Pile foundations are a reliable and versatile solution that can provide strong and stable support for many construction projects, particularly in cases where traditional shallow foundation systems are unsuitable.
