Pile design & pile construction services UK

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.

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.

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.

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.

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.
