A Quick Comparison between Concrete Bored Piers and Screw Piling
December 14, 2022Building and construction companies utilise different materials and techniques to ensure they can carry out their tasks without any issues. One of the tasks that their teams must often complete optimally is laying the foundation of buildings.
There are many reasons why foundations are vital to buildings. First, they help distribute a load of these properties to a larger area of the support underneath them. Foundations also provide stability to the components of the properties, ensuring that they remain secure despite the movements on the ground. One more reason foundations are essential to buildings is they can deter differential settlement of their structures.
Now, two foundation piles that can be used by building and construction companies are concrete bored piers and screw piling. These options have their advantages and limitations that make them useful in specific applications.
Concrete Bored Piers
Concrete bored piers involve boring a hole to install steel reinforcement cages. Concrete is then poured into the hole to support the foundation of buildings.
One great thing about concrete bored piers is they can perform optimally in areas with deep sand. Hence, buildings that will be erected on coastlines can easily take advantage of this foundation pile option. Another thing about concrete bored piers that makes them advantageous to some properties is they only emit less noise and vibrations. This benefit can help contractors carry out their work without disrupting the peace of their surrounding community.
Screw Piling
Screw piling, alternatively, uses long steel anchoring systems to effectively generate deep building foundations. Unlike concrete bored piers, this option does not have to bore a hole in the ground. Instead, it drills screw piles in the ground to actively support the foundation.
One benefit of screw piling is it prevents spoil generation. Screw piling does not involve boring and excavating any ground elements. It does not even need to transfer ground elements from one place to another, making the process much cleaner. Screw piling is also eco-friendly as it can only disrupt a minimal amount of soil. Ultimately, this foundation piling option is cost-effective as it can carry out its processes without wasting too many resources.
Helcon Recommendation
While the concrete bored piers can be useful in specific applications, our team at Helcon generally recommends screw piling in many situations.
For instance, soil with a high moisture content can benefit more from screw piling than concrete bored piers. Concrete bored piers do not work well with a high water table. Concrete bored piers also require digging the shaft much deeper than the normal depth, which will only cost tons of time and money. Screw piling, alternatively, does not require these things for the screw piles to be installed and work properly.
Of course, screw piling is recommended for projects that do not want any leftover soil. The existence of leftover soil due to concrete bored piers forces contractors to move and transfer them, which might only consume resources. Screw piling, on the other hand, can be carried out without bringing in excavation tools and equipment.
