Ground Pavers?

I'm not sure I'd use wood as pavers. They will be exposed to moisture and warp/rot.

Hi Cathy, you will have to treat them first but it looks amazing. Donna from Funky Junk shared this tutorial on how she made a wooden path that might give you some ideas and tips - https://www.funkyjunkinteriors.net/2020/05/garden-themed-wood-walkway.html

Take a look through here, looks good, but would treat the wood before using them:

You can treat them with something similar to the pressure treating formula or you can paint with a preserving paint. Once you do that, you can put them down as pavers. You can do any shape and pattern you can imagine. I would also recommend you treat them for termites annually. I use Hi-Yield 38 Plus for our termite treatment. I just noticed a small stump in my yard covered in them yesterday so I would think this would be a concern for you.

Seems you’d have to treat the wood well. While it would probably look cool, it might not be sturdy and would eventually rot. So long as you know that going in, it would be a good look however brief.

without treating the wood first it will not last long in the elements so you would have to redo it over and over -

They won't last long but you will use just like a regular paver. I get about 8- 10 years out of large treated timbers in my yard meant for the weather so you won't get much time out of them. You can use them just like a regular paver. Dig out the depth of wood plus another inch and lay sand. Sink the wood in and fill in with pea gravel or more sand in between. Do not use any gloss they poly to treat or they will be too slippery to walk on. People go to great lengths to dig much deeper and add gravel then sand.......that is necessary for brick.

Wood slabs, not so much.

Hello. Pressure treated wood would always be recommended with any kind of ground contact. Both the moisture and insect threats could cause worrisome problems.

You need to be careful that they won’t be too slippery. Wet wood can get really slick
