Kiri Robbie Posted December 10, 2020 Share Posted December 10, 2020 When is a foundation classed as deep? Is there a minimum depth in metres or is it variable? Quote Link to comment Share on other sites More sharing options...
Martin Larisch Posted December 20, 2020 Share Posted December 20, 2020 A deep foundation element or pile is usually between 3-5 times deeper than it's diameter. This ratio can change depending on your regional standards and guidance documents. Quote Link to comment Share on other sites More sharing options...
