CFA Piling – Everything You Need to Know About It

When building a structure, the most important thing you need to focus on is its stability and durability. However, achieving this can be tricky, especially when the stability of the soil is compromised. Opting for piling is the best thing you can do to ensure the structural integrity and stability of any structure.

Piling is the process of hammering or drilling reinforced concrete piles deep into the ground to distribute heavy loads and stabilise structures. CFA piling is one of the best types of piling you can opt for in your building. This piling type offers various benefits as it’s highly effective and versatile. It’s considered the best choice for any building project. In this post, we will unveil everything that you should know about CFA piling.

What is CFA Piling?

CFA or continuous Flight auger piling is a type of deep foundation that involves drilling a hollow stem auger into the ground to the required depth. It doesn’t need any temporary casing. The auger is used for drilling and then filling concrete in these drilled holes.

When concrete is pumped through the hollow stem to fill deep holes, reinforcement is inserted into the wet concrete if needed. This method combines driven and bored piling techniques, offering a quick and effective solution for various ground conditions.

Benefits of CFA Piling

The primary reason behind the popularity of CFA Piling is the amazing benefits it offers. The following are some top-listed edits associated with this piling type. Let’s go through them without further ado.

Speed and Efficiency: It’s one of the most effective piling techniques as it’s a combination of two different approaches. It also makes CFA piling a fast method. You can rely on it for rapid installation of piles and speed up the construction process.

Minimal Vibrations: This technique reduces vibrations and noise as it doesn’t involve continuous hammering. It makes CFA piling an environmentally friendly option. Wildlife and structures close to the construction site will not get disturbed or damaged due to vibrations

Versatility: CFA piling is a highly versatile approach. It can be used in a variety of soil conditions, including loose, sandy, and clay soils. Apart from that, reduced vibrations and noise make it suitable for urban areas as well. This versatility makes it a preferred choice for many construction projects.

Cost-Saving: It’s one of the most cost-effective piling techniques. First of all, a quick installation process reduces construction time and labour costs. Wet concrete is directly filled in the holes, so no materials are wasted. Above all, these piles can last for a lifetime, adding to the durability and longevity of your structure. All these things make it a cost-effective option.

CFA Piling Process

CFA piling involves a series of steps. Let’s go through them.

Site Inspection

The first step is site investigation. When you opt for piling, a team of experts will visit your site to understand your requirements and suggest the best piling type. They will check the soil condition as it’s mandatory to determine the right piling type. A soil stability test is performed to check how much support it can offer.

Drilling

After investigation and initial consultation, experts will start the piling process. It begins with drilling deep holes using a flight auger. It is drilled into the ground to the desired depth. The benefit of using an auger is that it brings the soil to the surface, ensuring the stability of the bored hole.

Pouring Concrete

After drilling, concrete is poured into the bored holes. You can opt for pre-mixed concrete to reduce mess at the construction site and limit the wastage of material. Augur can be used to pour concrete as well.

Reinforcement

Reinforcement is the insertion of metal rods in the concrete to strengthen it. You only need it when the solid is extremely unstable and cannot provide any support. Apart from that, it’s also required when you have to support heavy or irregular structures.

Curing

After reinforcement, the piling is almost done. Now, concrete is allowed to cure. This step will be completed in 2 or 3 days, transforming wet concrete into solid piles. Now, you can build the structure.

Applications of CFA Piling

• CFA piling is ideal for constructing foundations for both commercial and residential buildings, particularly in areas with challenging ground conditions.
• It is widely used in the construction of bridges, highways, and other infrastructure projects that require deep foundations.
• CFA piles can be used to construct retaining walls, providing support and stability to excavated areas.
• It is suitable for building marine structures, where soil conditions may vary significantly.
• It is also used in the construction of industrial facilities that require strong and durable foundations.
