The Evolution of Piling: A Journey Through Time

Piling, an integral aspect of modern construction, has a storied history that spans centuries. From ancient foundations to the sophisticated mini piling techniques employed in London today, the evolution of piling reflects advancements in engineering and technology, mirroring humanity’s architectural ambitions. This blog post delves into the fascinating progression of piling methods, highlighting key milestones and the role of innovation in shaping the landscape of construction.

The Ancient Origins

The inception of piling can be traced back to prehistoric times when early humans used wooden stakes to stabilise structures against flooding. Historical records from the Roman Empire illustrate the use of timber pilings under bridges and aqueducts, demonstrating early engineering prowess. Notably, the Romans’ construction of the pile-supported foundations for the Pont du Gard in France stands as a testament to the durability of these ancient techniques.

The Industrial Revolution: A Catalyst for Change

The 18th and 19th centuries marked a pivotal era in piling’s evolution, driven by the Industrial Revolution. The introduction of steam-powered equipment enabled deeper and more robust foundations, facilitating the construction of unprecedented structures, including the iconic Eiffel Tower in Paris. This period also saw the advent of screw piles, invented by Irish engineer Alexander Mitchell, revolutionising the construction of lighthouses and piers.

How Mini Piling Contributes to Sustainable Urban Development

In the ever-evolving landscape of urban construction, the shift towards sustainable practices has become paramount. Among these practices, mini piling stands out as a beacon of efficiency and environmental consciousness. This innovative method not only supports the structural integrity of buildings in constrained urban spaces but also aligns with the principles of sustainable development. Let’s delve into how mini piling is making a substantial difference.

Reduced Environmental Footprint

Traditional piling methods often require large machinery, leading to significant soil disruption and carbon emissions. In contrast, mini piling involves smaller, less invasive equipment. A study by the Environmental Protection Agency (EPA) suggests that compact piling rigs can reduce soil disturbance by up to 75% compared to conventional piling. This minimal disturbance is crucial in densely populated urban areas, where the preservation of the surrounding environment is as important as the construction itself.

Material Efficiency

Mini piling techniques have been lauded for their material efficiency. According to the UK Green Building Council, construction accounts for approximately 60% of all materials used in the country, much of which ends up as waste. Mini piling counters this trend by utilising fewer materials more efficiently. For instance, segmental piles used in mini piling can be precisely measured and cut to size, reducing waste by up to 20%, as reported by the Building Research Establishment (BRE).

Energy Consumption

Energy conservation is another realm where mini piling shines. The smaller rigs used in mini piling consume significantly less fuel than their larger counterparts. Data from the Carbon Trust indicates that mini piling rigs can reduce fuel consumption by up to 30%, thereby cutting down the carbon footprint associated with the construction process.

Noise and Air Pollution

Urban construction is often associated with noise and air pollution. However, mini piling rigs produce considerably less noise, which is a boon for densely populated urban areas. A study by the London School of Economics found that noise levels on mini piling sites were about 15 decibels lower than traditional sites, greatly reducing the disturbance to local communities.

Durability and Longevity

Sustainability is not just about the construction process; it also encompasses the lifespan of the structure. Mini piles are known for their durability. The Federation of Piling Specialists (FPS) notes that mini piles have a life expectancy that matches or even exceeds that of traditional piles, often lasting for over 50 years. This longevity reduces the need for frequent repairs or replacements, thereby conserving resources over time.

Conclusion

Mini piling represents a significant stride towards more sustainable urban construction practices. Its reduced environmental impact, material efficiency, lower energy consumption, and minimal disturbance make it an ideal choice for modern urban developments. As cities continue to grow and evolve, embracing techniques like mini piling will be crucial in achieving a balance between development and environmental stewardship.

Different Methods of Pile Foundation

Whether you’re looking to build a new house or a large commercial building, piling is an essential aspect of foundations. However, it isn’t always the best option for all projects.

Fortunately, there are different methods of pile foundation in London to meet your needs and requirements. This article will discuss some of the most common options, including Driven Pile, Tremmied Pile, Underpinning, and Mini-piling.

Driven Pile

Driven piles are deep foundation elements installed using impact or vibration hammers to design depth and resistance. They can be precast concrete or steel H-piles and can be installed in one length or joined for deeper piles.

These piles can be a cost-effective solution for sites with non-cohesive soils, ground that has a high water table or soils that contain contaminates. It is important that a proper geotechnical investigation is carried out to determine the suitability of driven piles for a particular site.

They often gain capacity after installation, and incorporating this in the design can save on time and materials. This phenomenon, called ‘setup’, can reduce the number of pilings needed to accommodate a given load capacity and, in some cases, result in fewer piles driven with lighter equipment.

The goal of this study is to develop an automated formulation that achieves optimized pile-group designs for a particular soil type and for a given axial load corresponding to the weight of the superstructure. This optimization method is implemented in real-world cases in London and has resulted in foundation solutions that are economically more efficient than those that were originally implemented. The benefit in terms of construction costs varies from 7% to 33% compared to original solutions.

Tremmied Pile

Structural piling, one of the cornerstones of civil engineering, has been around for centuries – and is still used today. Pile foundations transfer load from a structure or building, into the ground and are an essential part of the sub-structure system.

When constructing piles, the method used to construct them is important and affects how they perform in the long term. There are two main methods of construction: driven piles and tremmied piles.

Driven piles transfer load by friction between the soil and the surface of the pile over its full length. They are constructed with a series of interlocking steel sheets and can be used to create both permanent and temporary retaining walls.

In addition to transferring load, piles are also essential for the protection of the structure and its inhabitants. They help protect the structure from landslides, cliff falls and floods.

Underpinning

Piling is a centuries old method of underpinning, but it has evolved in recent years. It has been used to underpin existing structures, as well as to create new basements and cellars.

There are many reasons why foundations can fail – tree roots, historic pipes, seasonal changes in soils can all contribute to subsidence. When these occur, foundations can become unstable and a new underpinning technique is required to stabilize and strengthen them.

One such method is the Underpinning (Mass Concrete) procedure, which has been used since the late 1800s. It involves excavating the soil below the existing foundation in stages or ‘pins’ until a stable stratum is reached.

This is then filled with concrete and allowed to cure before the next excavation begins. To transfer the load from the old foundation to the new, a dry sand-cement packing mortar is rammed between each ‘pin’ and then the concrete is poured in.

Underpinning can be a cost-effective option for subsidence, particularly in the case of shallow depths and where excavation would be difficult. However, the traditional method should only be adopted in the hands of an experienced structural engineer.

Mini-piling

Often used for projects where access is restricted, Mini-piling is an efficient method of creating foundations. Its small rigs can be adapted to get into confined spaces and fit through doors, especially in railway stations or elevator shafts where a standard driven piling rig would be too large.

The most common type of mini pile consists of a hollow steel shaft that is screwed or drilled into the ground and filled with grout or concrete to form the pile. This allows the soil to be supported throughout, reducing the need for extra supports, particularly in weaker, looser soils.

Another method of mini piling is sectional auger, which entails boring down and gradually adding multiple flight sections as the pile is built. This enables more flex in the pile, increasing its load capability.

This piling method is often preferred for ground conditions that are more sensitive to vibration and noise, such as densely populated areas or locations with adjacent buildings. It can also be used in places where it is difficult to get larger rigs into, like elevator shafts or inside buildings.
