Screw Piling: Revolutionising Foundations in Modern Architecture

An Introduction to Screw Piling

Welcome to the wonderful world of screw piling!

If you’re an Architectural Designer, you’ll know the importance of firm foundations. Here at Shear Architectural Design, we believe in staying on the cutting edge of foundation technology. That’s why we’re so excited about the innovative method that’s revolutionising foundation design – screw piling.

Whether you’re planning a house extension or mulling over a barn conversion, we’re with you every step of the way, helping to secure planning permission and ensure adherence to all relevant building regulations. Today, let’s discuss an approach that could save time, money, and a few headaches too: screw piling.

What is Screw Piling?

Simply put, screw piles are steel pipes with helices, similar to giant screws, which are driven into the ground. Screw piling, or helical screw pile installation, offers a quick, cost-effective alternative to traditional concrete foundations.

While screw foundations have been around since the 19th century, they’ve gained renewed popularity in recent years. The advent of steel screw piles, such as galvanized screw piles and mini screw piles, has broadened their application and made them more accessible for residential projects like house foundations or deck footings.

Are Screw Piles as Good as Concrete Piles?

Both concrete piles and screw piles have their benefits, but the latter offer a few distinct advantages. Firstly, they’re faster to install – instant screw piling indeed! There’s no need to wait for concrete to cure, meaning construction can continue immediately after the screw pile installation. This can be a real boon when working to a tight schedule.

Secondly, screw piles are less disruptive. Installation produces minimal vibration and noise, so it’s a great choice when trying to keep the peace with the neighbours during a home extension project! Plus, because the process doesn’t generate any waste soil, it’s a cleaner, greener solution.

Are Screw Piles Cheaper Than Concrete?

Cost can be a big deciding factor when choosing between concrete and screw piles. On average, screw piles tend to be more economical than their concrete counterparts. The savings are not just in terms of material costs, but also labour and time – and as any Architectural Designer will tell you, time is money!

However, the exact cost can depend on a variety of factors, such as the ground conditions, pile length, and required load capacity. If you’re considering a project that requires ground screw foundations, such as a house extension, loft conversion, or even a new build house, get in touch with us for a comprehensive quote.

The Strength, Types, and Versatility of Screw Piling

Having touched on what screw piling is, why it’s becoming the preferred choice over concrete piles, and the cost factors, we are now ready to dive deeper into this exciting method.

How Strong are Screw Piles?

Perhaps you’re an Architectural Designer dreaming up a grand, multi-storey project and wondering, can screw piles handle the load? The short answer is yes. Screw piles are renowned for their impressive load-bearing capacity.

The strength of screw piles comes from their unique design. The helical plates welded to the pile shaft help to distribute the weight evenly across the pile, ensuring a sturdy foundation for any structure. The load-bearing capacity can be further increased by adjusting the size, number, and position of the helices.

Whether you’re considering screw piles for house foundations, or needing screw pile footings for an ambitious deck project, rest assured that the strength and versatility of screw piling make it a reliable choice.

What are the 5 Types of Screw Piling?

Now that we’ve established the strength of screw piles let’s take a look at the different types available. There are numerous options depending on your specific needs and soil conditions:

  1. Steel Screw Piles: Known for their strength and durability, ideal for heavy-duty projects.
  2. Galvanized Screw Piles: These offer additional protection against corrosion, making them perfect for environments with moist soil.
  3. Helical Screw Piles: These are versatile and can be used in various ground conditions.
  4. Mini Screw Piles: Perfect for smaller projects with limited access or minimal disruption requirement.
  5. Adjustable Foundation Screw Piles: These allow for adjustment post-installation, offering flexibility during construction.

We at Shear Architectural Design can guide you through choosing the right type of screw pile for your barn conversion, garage conversion, or any other project you have in mind.

Can You Build a House on Screw Piles?

Absolutely! Screw piles for house foundations are an increasingly popular choice. With allstate screw piling or inland screw piling, it’s possible to build a house, extend an existing one, or even carry out a complete renovation. Our team has extensive experience in managing projects involving screw piling for house foundations. Whether it’s a new build, a loft conversion, or an ambitious renovation, we can help you navigate the process smoothly and efficiently.

Disadvantages, Removal, and Depth of Screw Piling

What are the Disadvantages of Screw Piles?

While screw piling boasts many advantages, no foundation method is without its potential drawbacks. For one, installation requires precise torque control to ensure the piles are driven to the correct depth and the design load is met. This may require specialised equipment, such as a screw pile attachment for excavators or skid steer screw pile attachment, and trained personnel.

Secondly, while screw piles can be used in a wide variety of soil conditions, they may be less suitable for areas with particularly hard or rocky soil. However, in our experience as Architectural Designers, these limitations are often outweighed by the benefits, especially when considering large projects such as a new build or small ones like screw piles for decks.

Can Screw Piles be Removed?

Yes, screw piles can be removed and even reused. The process is as simple as unscrewing the piles from the ground. This feature makes screw piling an attractive option for temporary structures or for those looking to minimise their environmental impact.

How Much Depth can a Screw Pile Hold? How Deep do Screw Piles need to go?

The depth to which a screw pile is installed can vary significantly, depending on factors such as the ground conditions, the load it needs to support, and the specific design of the pile. As a general rule of thumb, screw piles are installed to a depth where the soil is dense enough to support the structure’s load.
