Currently the floor of the barn is clay and rock which doesn't absorb a bit of water. We've been using sawdust and pelleted bedding. I think it would be a good idea to put a "sub-floor" of gravel (like a foot of it) and then put rubber stall mats on top. It seems like this would help our drainage issues a lot and make things a lot cleaner. Has anyone done this? How well does it work? It seems like you would use a lot less bedding. Does excess urine drain out through the mats or can you spray them down with water after cleaning up used bedding. (right now I can't imagine adding water to the mess ).
Right now I'm doing what I can by adding lots of absorbant bedding, but I can't keep adding this much this often. It's just a quick fix.
I'll attach some pics to show how the floor on the barn is slanted away from the mountainside (which you would think would help drainage more than it does). The pics were taken the day we got the horses home - believe me it hasn't been that dry since!
