Hole Depth for Sign Posts

Post Planting Depths

All builders, good or bad will have a preconceived idea of how far underground a post should go. Indeed as there are so many variables, there is no substitute for experience.

However the chart opposite is a good starting point. We would suggest with heavy oak posts with arms to go a little deeper.

The chart is also assuming you are concreting in the posts - again if just earth ramming the holes will need to be deeper.

This are just guides - for more information you could contact your local civil engineering department.
