I am a newbie and I built the 12x16 shed which is described in the Sobon timber frame book, just like many others have done.I am going to use the shed as my blacksmithing shop. I like a dirt floor in my shop and filled in the space between the 4x8 floor joists with sand screenings. The roof is on so this should stay dry, but my neighbor warned me that the floor joist would rot if covered in this manner. Is this something I need to change? I sure dont want to have to dig out several yards of sand?I am on a ridge and drainage is good?
Thanks,
Bob
