Screw piles are a type of foundation system now widely used in the construction industry. They can offer significant advantages in terms of speed and ease of installation and by offering a reduction in the offsite disposal of drilling spoil. Screw piles can also be used where the shape, size and location of the structure cannot be supported by alternative foundation methods.

Screw piles can be used for the following: 

New foundations Support to new structures including:

  • Residential, commercial and industrial buildings 
  • Transmission towers and wind turbines 
  • Transportable buildings. Etc

Screw piles are wound into the ground, much like a wood screw. The helical flights and shafts are specifically shaped and designed to suit the ground conditions. For permanent applications once the pile has reached the target depth the shaft is typically filled with concrete. In some cases this can increase the capacity of the pile.

Advantages, Disadvantages and Suitability of Screw Piles:-

Advantages:-

  • Possible to install in areas with poor accessibility, for example, where there is low headroom or other types of confined spaces.
  • Reduced disposal costs
  • Simple to remove
  • Can be installed in almost any climatic condition 
  • Minimal construction noise during installation

Disadvantages:-

  • Soil corrosion factors may limit life.
  • Hard layers may prevent embedment of the screw pile

Screw pile foundations are still used extensively, and their usage has extended from lighthouses to rail, telecommunications, roads, and numerous other industries where fast installation is required, or building work takes place close to existing structures because of there ease in installation & reduced costs.
