Using Multi-turn Helix as the Main Screw Piling Solution

October 24, 2022

Most construction projects begin with the foundation creation before proceeding to other phases. Ensuring that the foundation is stable and secure can make any buildings on top of the said area to be free from issues and problems. 

Without prioritising the foundation, buildings may gradually attain damage to their structural components, which can then lead to their complete deterioration when the ground moves. Flood may likewise damage the buildings easily if their foundation is not built optimally. Fortunately, contractors can already choose from a wide array of foundation methods and carry one out to avoid these problems from occurring.

One foundation method that is deemed effective for many construction projects today is screw piling installation. This method involves the driving of screw piles into the ground until they reach the target depth. Upon reaching the target depth, they are then filled with concrete.

Benefits of Using Screw Piles 

The use of screw piles in setting up the foundation of construction projects can provide tons of benefits to both contractors and property owners. 

For one, screw piles can make the contractors’ job fast and convenient. Unlike other foundation methods, driving the screw piles into the ground does not involve a lot of time and effort. The only thing contractors need to do is install them and fill them with concrete upon reaching their target depth. All these time-saving activities can then be advantageous for property owners as they do not have to spend a lot of money anymore. 

Aside from saving resources, the installation of screw piles can also be beneficial for construction projects as it does not create tons of mess. Some foundation methods have to excavate a huge ground area first before installing the necessary foundation materials. The use of screw piles, alternatively, does not require this type of excavation. All they need is to be installed deep within the ground, making sure that they do not generate any waste.

Maximising Multi-turn Helix 

All types of screw piles can provide the aforementioned benefits, but some of them still provide more advantages than others. The added advantages of some screw piles can be associated with their general design. Multi-turn helix, for instance, has a screw pile shaft butt welded to the end of the helix. This design provides more stability to its assembly for load transfer. It also enhances its overall load-carrying capacity.

The unique properties of a multi-turn helix help it penetrate clays, gravels, and shales without any problems. Its penetrating capability can even be enhanced if it is created out of durable materials like cast steel alloy. Another advantage of a multi-turn helix is it can be removed and reused. When installing temporary structures, it would be best for contractors to use multi-turn helix as it can be unscrewed and moved to new places flawlessly.

One more advantage of a multi-turn helix is it can minimise the impact on the environment. Installing this type of screw pile does not harm any soil-dwelling organisms as it does not involve the use of harsh concrete chemicals. It can even leave the soil structure intact, making the foundation as stable as possible.
