Next, they pour concrete into the shell to secure the foundation. Thus, it retains the advantages of each method.įirst, workers drive a steel shell with the same diameter as the pile into the ground. Combined pile foundationsĬombined pile foundations use a mix of the driven pile foundation process and the cast-in-situ pile foundation process. This allows them to tailor the depth of the foundation as per the project's needs and use piles with a smaller diameter than the ones used for driven pile foundations. Rather than bringing in precast piles to the construction site, workers drill holes into the ground, place steel reinforcements inside and then fill the hole with concrete instead. Cast-in-situ pile foundationsĬast-in-situ foundations use concrete piles. In fact, this has the opposite effect on the soil because it decreases its ability to support heavy loads. The watery condition deters the compaction of the soil when you drill piles through it. However, this construction method is not suitable for saturated silty soils that have a poor drainage capacity. This compaction of soil increases its density and therefore, its bearing capacity. In granular soils, these piles displace an equal volume of soil, helping the soil become more solid. Similarly, contractors order prefabricated steel and timber piles that they can drill directly into the soil with a piling hammer. Concrete piles are precast before they arrive at a construction site. Driven pile foundationsĬoncrete, steel and timber are the most common materials used to make piles for the driven pile foundation method. Related: Highest Paying Constructions Jobs 1. The following describes three common methods of using piling types in construction: At this stage, their goal is to use a piling type that boosts the longevity and structural integrity of the foundations below their build. Using this information, they can prepare for construction challenges and decide on the most suitable piling type. They will also need to consult with architects to understand the scale of their infrastructure project. How are piling types used in construction?īefore building engineers can decide between piling types, they need to assess the conditions of their construction site, such as the soil, climate and other relevant factors. When it becomes impossible to keep the foundation trenches dry by pumping or by any other measure When soil excavation is not possible up to the desired depth because of poor soil condition When there is a canal or deep drainage systems near the structure When there is the possibility of scouring, because of its location near the river bed or seashore When the soil at shallow depth is compressible Other types of foundations are costlier or not feasible When a heavy load of a superstructure needs additional support Here are a few situations when using a pile foundation system can be essential: Their primary purpose is to ensure the safety and strength of the ground before workers build anything above. There are several factors to consider when using a piling foundation during construction. Related: What Is Construction Project Management? When to use piling foundations in construction Essentially, pile foundations work by distributing the weight of heavy construction across a wider surface area. In this case, engineers need to consider overturning forces from winds or waves. For example, piles may need to carry uplift loads to support taller structures, such as skyscrapers. Its shape, circumference and weight may vary depending on the conditions of the soil and the demands of the project. Piles usually are long poles that are made of timber, steel or concrete. Piling prepares the ground to carry heavy loads, such as a new home, office complex, road or another piece of infrastructure. Piling is the process of drilling foundations through the ground to provide more structural strength to the weak soil underneath. Related: How To Get a Construction Job What is piling? In this article, we cover what piling is, describe when engineers use it, outline how different piling methods work and list common types of piling. If you're seeking a role in the construction industry, it's essential to be knowledgeable about the different piling types and methods. Piling is an important technical skill that requires confidence and a collaborative team dynamic. It's a key step in the construction process that contractors use to boost the safety and reliability of a project. Building engineers use piling to secure the foundations of a construction site before they begin building infrastructure on top.
