In August of 2023 I dug a hole in the ground to put my radio tower in. I’m not always the most physically capable person, but I have my days. When I did this I had decided I would try “Secure Set” expanding foam from GRA Services. I ordered a utility pack and had contacted the company to determine the volume of the foam in question. It’s been a few years, but I believe the package I ordered was roughly 12 ft³. I thought I would do a blog post with the “2 years update” on that, since it’s a question I sometimes get. I also thought I would include some retrospect tips I thought I would share if I ever had to do it again.
