Screw pile foundation is one type of foundation that is used for construction. There are many advantages of using this type of foundation. One advantage is the speed with which this foundation is constructed. The installation process a track excavator or it can be done with a mini excavator as well when it has the right requirements. The speed of the process comes from the minimal use of special equipment. This way the normal equipment on site can be mobilised easily. For a typical construction, one operator and labourer will be sufficient.
The piling technique is such that it can be loaded straightaway after it has been installed. You won’t need to wait for the concrete or the grout to become hardened. This can be very advantageous in the case of emergency construction where you have a very tight schedule and the project needs to have the foundation done right away to proceed with the construction process. The ultimate capacity of screw piles has a tendency to increase with time in most cases. This is also a positive sign.
The installation doesn’t take much time and another advantage is that the process does not depend on weather conditions as it does when it comes to concrete piers. There is also very little disturbance to the site. When it comes to other foundation systems such as driven piles, drilled piers etc. there can be some disturbance. As this method doesn’t give rise to any soil cutting, the site will be kept more or less clean. There will be less to clean up at the end of the day as well. This will indicate a lower cost for the project. Another thing you would’ve noticed is the excessive notice that comes with the installation of most piers and piles. In the case of screw piles, this noise is minimised to a large degree. Therefore, they are ideal for projects that include restoration or retrofitting as the existing buildings will not be disturbed very much.
You can verify the load capacity during the installation of the screw pile. This is very important when it comes to the construction of big buildings. This can be done by the use of a pile driving analyser in the installation process. This type of foundation is ideal for construction projects that are taking place at remote locations. This is because the cost for mobilisation is quite low and there isn’t much equipment that are needed for the installation. These screw piles can also be used as modular systems when the site only allows for minimal access. They can also be used in high groundwater conditions.
