Piling is a cost-effective approach to improve the life expectancy of a structure significantly. Most modern structures and buildings today are supported by it, ensuring their solid foundation. Therefore, it is of utmost importance to choose the best piling service for your project. In this article, we talk about piling and why you need piling services.
What is Piling?
Piling is a fundamental building method that has been used for ages. Since then, it has been utilized in the foundations of every type of building, including off-shore wind farms and enormous industrial warehouses.
Simply explained, piling refers to the process of driving structural piles into the earth that will serve as the building’s foundation. There are numerous types of piles, which can be categorized according to their weight transmission mechanism, installation methods, and material of construction.
What is the Pile Foundation?
Long poles constructed of steel, concrete, or wood are used as piles in foundations. They are afterwards buried in the earth to transfer the weight of buildings to denser, deeper soil that can support the load. The earth that surrounds the pile foundation gets compact. The piles are held in place by the shifting of the dirt that originally covered the region where the foundation currently stands. The foundation is deeper in taller buildings.
What are structural piles made of?
The technique of piling can involve a wide range of various materials. The most popular piling materials are often wood, steel, or concrete.
Piles come in two primary categories: replacement and displacement. To replace them, new piles are inserted into the holes or excavated from the ground. Pre-formed displacement piles are pushed into the ground, displacing the soil they pass through.
When are these structures used?
To solve the issues caused by poor ground conditions, advanced research led to the development of piled foundations.
Piling can be advantageous to use when:
- When a site evaluation reveals that the ground is unsuitable and unworkable to a depth of more than 2 meters.
- A high water table exists.
- Traditional deep trench foundation excavation is extremely expensive in terms of removal costs.
- If there are soils, like clay, that could potentially expand or contract excessively depending on how much water is there.
- When the foundation trenches are unstable and health and safety are a concern.
- When a thin layer of porous soil is present at the surface. Loads of the building must move beyond this layer and onto the layer of firmer soil or rock that is beneath the weak layer since it is unable to hold the weight of the building.
- When a structure, such as a high-rise skyscraper, bridge, or water tank, is subject to exceptionally heavy, concentrated loads.
Common Pile foundations
The two most common pile foundations are:
● End Bearing Piles
End-bearing piles rest their bottom end on a bed of particularly robust soil or rock. Through the pile and onto the sturdy layer, the building’s weight is transferred. The bottom end sits on the surface, which is the junction of a weak and muscular layer, and this is the fundamental idea. As a result, the load is safely transferred from the weak layer to the strong layer.
● Friction Piles
The way friction piles operate is different. Through friction, the pile distributes the weight of the building to the ground along its whole height.
