I used this because we had a slope to our property, fixed the slope but not enough. My barn was muddy as hell. Used this grid, rock dust and rubber matts and now have no more wet barn! I want to do my whole barn in this, but in due time. Also did it outside of the stall because my horses run in and out at free will and it has held up thus far. Just packs down and drains so mych better now too.
