What Are H-Section Piles?

H-Section piles, also known as H-piles or H-beams, are structural square beams that are shaped like the letter ‘H’ in profile. These piles are widely used to add stiffness and support to sheet pile walls, King Post Walls and other deep foundations. H-piles are made from steel and available in different sizes for various project needs.

H-Section piles are particularly effective due to their high bending resistance and strength, which make them suitable for heavy loads and expansive soils. They are commonly employed in the construction of bridges, docks, and large buildings, where a deep foundation is critical for structural integrity. H-piles work well in both compression and tension, allowing them to handle the lateral forces and vertical loads associated with complex engineering projects.

The installation of H-Section piles includes the following steps:

1. Site Preparation – The installation site is cleared of any debris, and the ground is levelled. This preparation is crucial for the stability of heavy machinery used during the installation process.
2. Pile Positioning – Each H-Section pile is positioned precisely where it needs to be driven into the ground. This is usually determined by engineering plans and site measurements. A piling rig is used to carry and manoeuvre the piles.
3. Driving the Pile – The piles are driven into the earth by pile-driving equipment such as a vibratory hammer. [2] The tough and durable cross sections provide excellent driving characteristics when driving in difficult soil and rock conditions.
4. Cutting to Size – Once the pile is driven to the required depth, it may need to be cut to a specific height to align with the design requirements of the structure it will support.
5. Capping – After cutting, a cap is often placed on top of the piles to distribute the load evenly across the pile’s surface when the structure is built on it.
