Screw Piles, Screw Anchors or Helical Anchors

Helical piles, sometimes referred to as screw piles, screw anchors or helical anchors, are a steel screw-in piling and ground anchoring system used for building deep foundations. Screw piles are manufactured using varying sizes of tubular hollow sections for the pile or anchor shaft. They are installed by rotating them into the soil, a bit like a wood screw.

John Lawrie Tubulars can custom fabricate welded helical piles and extensions to your designs, specifications, and quality requirements, and deliver directly to your project site.

Our new patented Endformed piling products have been developed to be more cost effective and to save time in the field.
