Mini piling is a type of piling technique commonly used in construction projects with limited access or headroom. It is a quick and cost-effective method of creating a solid foundation for buildings and other structures. One of the most common questions people have about mini piling is how deep it can go. In this article, we will discuss the maximum depth of mini piling and how it can vary based on a number of factors.
The depth of mini piling can vary depending on the type of soil and the load-bearing capacity required for the project. In general, mini piling can go as deep as 25 meters. However, this depth can be limited by factors such as soil conditions, groundwater level, and the piling rig being used.
Soil conditions play a significant role in determining the maximum depth of mini piling. In soils with low bearing capacity, mini piling may not reach a depth of 25 meters. In such cases, it may be necessary to use other piling techniques such as CFA piling or rotary auger bored piling to create a solid foundation for the structure.
Groundwater level is another factor that can limit the depth of mini piling. If the groundwater level is high, it can interfere with the installation of mini piles and limit the depth to which they can be installed. In such cases, it may be necessary to use a different piling technique or install a dewatering system to lower the groundwater level before commencing with the piling works.
Finally, the type of piling rig used can also impact the maximum depth of mini piling. Different types of rigs have other specifications, and some may not be able to reach a depth of 25 meters. It is essential to consult with an experienced piling contractor who can assess the site conditions and recommend the most appropriate piling technique and rig for the project.
In conclusion, the maximum depth of mini piling can vary based on many factors such as soil conditions, groundwater level, and the piling rig being used. While mini piling can go as deep as 25 meters in ideal conditions, it may be necessary to use other piling techniques or dewatering systems to create a solid foundation for structures in challenging soil conditions.
