I had this problem as well and started pulling my mats every few weeks and sprinkling lyme underneath them, it really draws all the moisture out and helps keep it dry but it is a back breaking job. It did help a little but the biggest impact was switching my bedding to local sawdust from a lumber mill. It really absorbs the urine and keeps it contained to a small spot rather than being able to flow everywhere. Its also much easier to pick out my stalls now and I have MUCH less wasted bedding (even my manure pile is smaller and breaks down faster!!! ). In my area one pickup truck load does roughly about 5 12x12 stalls a week for only $20 but you can usually get them delivered in larger quantities for under $100.
I also tried pelleted bedding too. It worked well but was not cost effective for me and too time consuming as each bag has to be watered down in order to puff up and absorb urine (if not you are left with rock hard pellets that are hard to walk on and roll all over the place so I can only imagine what my horses would think of them). Plus when you water them and they puff up and break apart, they literally turn into a pile of fine sawdust!!! It took 5-6 bags to do my 12x12 stalls and only lasted about 1 week for my really messy guys. I'm sure you can find youtube videos on pellet bedding to help you decide what would be best for you. Depending on where you are it may be more cost effective for you, just wasn't for me. That being said however, I would use pellets any day over shavings after seeing how much better they absorb and how much easier and less time consuming it was cleaning stalls.
