We have a earthen floor now. It is composed of a green colored shale (green clay and frac sand) that was taken from a nearby hillside when the site for the building was leveled. It is a 50x90 pole barn. The floor is very hard but forms a fine dust layer that is a mess if it gets wet. Dusty if dry or sticky slippery goo if wet.
I could use some to form bricks and experiment with different ratios of stabilizers. I am sure I can get a very hard surface but I wonder about how it would handle heavy equipment, or repeated foot traffic, Wisconsin winters,freezing/thawing and such. I saw a video were someone was using a garden tiller and a garden hose to mix concrete into his floor which was leveled with trowels once the material was well mixed/soft and left to air dry slowly.
I will try to go slow and figure this out. Still open to suggestions,Thanks
