OK, I read the page and while it's a good idea, it is a huge amount of work, not to mention a lot of material! Yikes, 3' down for gravel. They are, of course, a big horse stall/barn prep. Of course, you DO have a big horse, Marty.
Personally, I have a great sand based soil. So, I used the rubber mats in front and woody pet/shavings at the rear only. It has worked fine. I have considered digging out the rear of each, adding gravel over the sand/loam dirt and then covering with the dirt I had removed -- and adding a holed mat over, then shavings. AGAIN, a whole lot of digging to give a little more depth of drainage...and I don't have a problem now. My barn isn't a large as you were able to get put up there in TN !
Let us know what you decide, Marty. You might make me feel like I need to do something
. I have gravel, shovels, time and no help! Of course, I'd have to shovel this gravel myself from the extremely over rocked driveway, take to barn, etc. Wow. Lots and lots of work -- want to send me your two sons?
Oh, hey, I saw those rubber bricks at a horse expo...cool! Well, except for price and that was so hot it was not touchable. I have enough of the durock board (behind bath tile) to line the isle of my barn and I intend to level and place that in there. I've had some pieces along the door entrances on the outside for about 3.5 years now. It was placed onto the ground which had been smoothed down to a level but slight angle, as a test. I'm amazed at how well it has held up out there! Since there will be drainage between the pieces it should be ok. I use a light bleach wash down 2-3 times a year, that helps control odors, molds, germs, etc. at least a little bit. Hey, it IS a barn not a hospital.
