I have a Little Free Library set on a 4x4 post. How do I securely bury it?

  • You need to dig a post hole to at least 3 feet below the soil surface or about a foot below your frost line in your area. When digging this try to create a bell shape hole with the bottom being wider than the top. Doing it in this fashion helps prevent any frost heave from pulling the post up during the winter. Set post into hole and follow up by using fast setting cement. You can forgo all the mixing simply place the dry material around the post making sure the post is level. Then use a bucket of water and pour in onto the cement. This will be enough to start the hardening process. Over time dampness in the ground will harden the rest of the cement. If your in an area where they tend to run over or break your mailbox posts. Purchase the plastic post covers that they use for 4x4 fence posts. Cement that into the ground and simply place your new mailbox post into it. If it gets damaged, simply remove and replace with new post. Leave the plastic part up about four inches around the top from above the soil surface, drill small hole and using screw secure the post into it. Then using a silicon caulk seal around the edge so water does not fill into the space between the post and the plastic sleeve. This will assure that the post will not rot or decay from water.

    Looks like you already have a fabulous (and worded better than I could have done) answer to your question. I have often considered doing a Little Free Library, but my home is not in an ideal location... I hope you will post or send a picture of it!
