CFA Piling
CFA Piling Services
Continuous Flight Auger (CFA) piling involves drilling downwards with a hollow auger. Once the required depth has been reached, concrete is injected through the auger as it is pulled up and out of the hole. In doing so, a continuous reinforced concrete pile is formed, which stops at ground level as the auger reaches the surface.
CFA piling is an efficient technique if carried out by a trustworthy CFA piling contractor in London, being used with most ground conditions and having the advantage of causing very little disturbance to surrounding areas.
What is CFA Piling?
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While the pumping is in progress, the drills are withdrawn slowly, extracting the soil with them and forming a fluid concrete shaft that extends to the ground.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.
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.
Quietest Construction
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.
Ideal for highly moist Soil Conditions
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.
