Hi. I recently moved to a 5.5 acre property with a well-built existing horse barn. Unfortunately, the previous owner has allowed neighbors with cows to have free run of all three outward facing stalls and the manure is piled high in each stall. I got one stall down to what I have confirmed (via text to previous owner) is crushed limestone. However, it is totally saturated and uneven from years of cows going inside each stall and poor upkeep.
I would like to improve drainage and the base in general and eventually put mats and bedding down, but for now I am letting the current stall that is down to basically the crushed limestone air out.
Do I just put new rock/limestone/sand on top? Do I have to figure out how to dig out the old limestone? How do I figure out a drain situation?
Also, I am open to other options, like asphalt/concrete. Does it go directly above this soiled limestone?
All advice welcome. I will eventually redo all three stalls, but one at a time because I am having a hard time getting the neighbors to take their cows out. We've been here three weeks.
