Piling is a foundation-building and reinforcing method. It is used in commercial, industrial, public, and residential construction. There are several types of piling methods, including CFA or continuous flight auger piling, SFA (sectional flight auger), driven piles, and many more. Our highly qualified and experienced construction team has been providing piling services throughout London, and we have completed numerous projects to the complete satisfaction of our customers.
CFA piling involves the usage of continuous flight augers, the augers are hollow stemmed. The augers are drilled to the recommended depth, and liquid concrete is pumped into the hollow augers. While the pumping is in progress, the drills are withdrawn slowly, extracting the soil with them and forming a fluid concrete shaft that extends to the ground. Reinforcing cages are then inserted into the concrete shafts. The entire process of soil extraction and concrete pilling is simultaneous.

The CFA piling technique is ideal for locations with numerous buildings. For instance, a residential community. Construction work, especially foundation building, can affect nearby structures’ integrity. However, CFA piling produces minimum vibration, which does not affect adjacent structures. It also has very low noise, making it ideal for carrying out construction work in and around sensitive properties such as hospitals. This quality also makes it highly suitable for construction in areas which are governed by building regulations. If you are building residential or commercial property in a sensitive or crowded place, contact our CFA Piling contractors London.
A high moisture content soil is not ideal for any construction. Not only will the construction work be extremely difficult, but it will also be highly risky. Temperature changes can make the soil shrink or expand too much. This could challenge the integrity of the infrastructure in question. Therefore, for such ground conditions and for building on water-bearing strata, the ideal method of foundation building is piling. CFA piling allows the transfer of the building load to the piles and onto more resistant strata with low moisture content. CFA piling is also ideal for construction on strata like gravel, soft rock, silt, sand, and many more.
As the CFA piling process involves continuous flow, including extraction of soil and pouring of concrete, it is a much quicker piling process than others. This makes it highly ideal for projects which need to be completed quickly and are short on time. Community hospitals, fire stations, police stations, houses, etc., can all benefit from CFA piling to reduce construction time. Contact our CFA piling contractors London for quick and reliable construction of foundation piles.
CFA piling is carried out with the help of rigs. This reduces construction time and labour costs. The method takes less time than other techniques, so you need fewer labour hours. Therefore CFA piling can be really helpful for projects with budgetary constraints. Foundations built with this technique last a lifetime and are unaffected by external factors. Even if repairs or reinforcement are required, they can be conveniently carried out without disrupting the main structure.
CFA piling can not only be used for building new foundations, but it can also be used for reinforcing existing ones. Regardless of whether it is a residential or commercial property, many factors can weaken the quality of your foundations. Our experts can use the CFA piling technique to reinforce your foundations and protect your property.
Our CFA piling contractors London begin by analysing your site and inspecting the soil condition. To identify the most suitable piling method, all factors are considered, including the moisture content, climate, load-bearing value, and presence of adjacent structures. CFA piling rigs are transferred to the construction site, and the construction process is carried out under the supervision of our experienced and qualified civil engineers. We use state-of-the-art CFA rigs to provide cost-efficient and timely construction of piling foundations.
