Foundation piling is essential for providing a strong and stable base for structures, especially in areas with weak or unstable soil. Piles are long, slender columns made of materials like concrete, steel, or timber that are driven deep into the ground to reach stable soil or rock layers.

Foundation piling is usually used in specific situations. This method transfers the load of the structure to deeper, more stable strata, preventing settlement and structural damage. Foundation piling is crucial for tall buildings, bridges, and other heavy constructions where traditional shallow foundations would not be sufficient.

These situations include:

• when the soil has a weak structure, or
• when there is a layer of weak soil on the surface.

Since the layer can’t support the weight of the planned building, foundation piling contractors use foundation piling to transfer the loads to a layer of stronger rock or soil underneath. Suppose the proposed structure is very heavy and concentrated in its configuration – for example, a high-rise building or a water tank. These structures would exert direct pressure on the ground stabilising it. While not exactly concentrated, bridges can also be supported by foundation piling, especially because it supports large loads (people and cargo) daily.

For load-bearing projects, foundation piling contractors use long, slender columns made from steel, reinforced concrete, or even timber. In fact, wooden piles still play a crucial role in jetties. Concrete piles, on the other hand, are precast, made at ground level, and then driven into the ground through hammering.

Steel foundation piling is shaped like an ‘H’, and these are designed to take heavy loads, saving time during construction. There’s also no casting process. Foundation piling contractors should be studying the soil to ensure that whichever deep foundation solution they use won’t overload the ground beyond its load-bearing capacity.

End-bearing piles pass the load through the lower tip of the pile because the bottom end is embedded within or on top of a strong layer of soil or rock. Essentially, end-bearing piles are a kind of transition between a weak layer and a strong foundation layer.

Friction piles are unique — they transfer the load of the building to the soil by the frictional force between the foundation piling’s surface and the soil. These soil types include sandy clay, clay, sandy soil, and more.

For lateral support, foundation piling contractors rely on sheet piles. These help resist lateral pressure from the flow of water or loose soil. They can be used in situations like:

• The construction of retaining walls
• Shore or riverbank erosion protection
• Helping to retain loose soil around foundation trenches
• Confining soil or isolating the foundation from adjacent soils

The solution that foundation piling contractors will use depends on factors like:

• The total load from the structure
• Soil conditions
• Water level
• Available resources
• Cost
• Noise and vibration allowances within the area

The cost for deep foundation solutions depends on what type of material foundation piling contractors use, whether the job requires industrial and mechanical excavations or can be hand-dug. It also depends on what kind of project you’re working on — commercial, large-scale projects, building a single residential dwelling, or a multi-unit high-rise structure. In general, however, foundation piling is more expensive than shallow foundations because of the amount of specialist labour work involved.

It’s difficult to determine exactly how deep foundation piling should be installed because there are many factors involved including what type of foundation piling you’ll use, what type of soil you have, and how much the load is anticipated to be.

This means a foundation pile could be driven up to 100 feet or as little as 7 feet. It’s important to install foundation piling to a significant depth, however, so it can handle the load it’s designed to bear. The depth also depends on the length of the pile, and usually, it needs to go beyond 10 feet deep for it to be a truly deep foundation solution.

Pile foundations are designed to be highly durable and can last for several decades, often exceeding 50 to 100 years. The lifespan of a pile foundation depends on various factors, including the material used, the environmental conditions, and the quality of the installation.

Concrete and steel piles generally offer longer lifespans compared to timber piles, which may be more susceptible to decay if not properly treated. Regular inspection and maintenance can also extend the longevity of pile foundations, ensuring they continue to support structures effectively over time.

The choice between piling and footing depends on the specific requirements of the construction project and the soil conditions. Piling is generally preferred for structures on weak or unstable soils, as it provides deep support and stability by transferring loads to stronger soil layers or bedrock.

Footings, on the other hand, are suitable for projects on firm, stable ground where shallow foundations can adequately distribute the load. Each method has its advantages, and the decision should be based on a thorough geotechnical investigation and the load-bearing requirements of the structure.

The depth of a piling foundation varies depending on the project requirements and soil conditions but typically ranges from 3 metres to over 50 metres. In some cases, piles may need to be driven even deeper to reach stable soil or bedrock. The depth is determined by geotechnical engineers based on soil tests and the load-bearing capacity needed for the structure. Different types of piles, such as end-bearing piles and friction piles, may require different depths to achieve optimal support.

Foundation piling involves the use of long, cylindrical columns made from materials like concrete, steel, or timber. These piles are driven deep into the ground using pile-driving equipment. The visible part of the process includes heavy machinery such as pile drivers and drilling rigs on the construction site.

Once the piles are in place, only the tops of the piles are visible, protruding slightly above the ground level. These tops are then capped and connected to the structure's foundation, providing a stable base for the construction. The completed pile foundation is usually covered with the building's footing or slab, making it invisible in the final structure.
