Sheet piling is a fundamental component in modern construction projects requiring earth retention, groundwater control, and structural support. These interlocking steel sheets provide both temporary and permanent barriers used in a variety of applications such as cofferdams, seawalls, basements, and below-grade structures.
Sheet Pile Types and Materials
Sheet piles come primarily in two forms: hot-rolled and cold-rolled steel. Hot-rolled piles are traditional with better water resistance and stronger interlocks, making them ideal for marine or long-term installations. Cold-rolled sheet piling is less expensive and offers quicker installation but may provide less resistance to water penetration.
Interlocks allow individual sheet piles to mate tightly, forming continuous walls. Ensuring these interlocks are clean and properly sealed is essential to prevent groundwater seepage. Products like bituminous coatings or foam sealants are often applied to interlock areas for enhanced water tightness, especially in permanent walls.
Common Installation Methods

• Panel Driving: Multiple sheet piles are assembled into panels before installation using a guide frame or template. This method improves vertical alignment and reduces leaning, especially useful for soft soils or permanent structures like basements and underground car parks. While more time-consuming, panel driving provides superior tolerance control.
  
• Panel Driving with Staggering: Similar to panel driving but involves reinforcing alternate piles with tips driven deeper to better penetrate compacted soil. This method is efficient in dense soil environments.
  
• Pitch and Drive: Single sheet piles are positioned and driven individually, making this a faster and lower-cost option. It is commonly used for shorter piles or temporary walls where alignment tolerances are less stringent. This method is well suited for less compacted soil and smaller projects.
  
• Press-In Method: Using hydraulic or mechanical presses, sheet piles are pushed gradually into the ground, producing minimal noise and vibration—an ideal method for urban or sensitive sites. Japanese-made pressing rigs that crawl along piles without needing lifting between operations exemplify this technique’s advanced approach.
  
• Vibratory Hammer: A machine applies rapid vibrations to loosen soil for easier driving of piles. This is effective in sandy, gravelly, or cohesive soils but less so in dense soils.
  
• Impact Hammer: Direct, powerful blows are used to drive piles into very dense or hard soils, often following pre-driving with vibratory hammers.
  

• Jetting: Injection of water near the pile toe to reduce soil friction and assist penetration.
  
• Pre-Auguring: Drilling ahead of piles using continuous flight augers to loosen soil without removing it, facilitating easier driving.
  

• Sheet Pile: Steel sections driven into the ground to form retaining walls.
  
• Panel Driving: Assembling multiple sheet piles into panels for unified installation.
  
• Pitch and Drive: Driving individual sheet piles directly into the ground.
  
• Interlock: The joint mechanism that connects sheet piles side-by-side.
  
• Jetting: Using water to loosen soil around piles during driving.
  
• Press-In Method: Slowly pushing piles into the ground via hydraulic presses.
