When it is REALLY humid, the matts in the aisle will get damp. That’s what worries me about the belting in the aisle.[/QUOTE]
I have rubber roofing material called ice dam I believe - very thin, held in place by fencing staples (my redneck solution to edges blowing up) - in my aisle, laid over stonedust floor.
I got it for free from one of the guys who built my barn & was redoing his roof.
12yrs later it has stood up to horses walking & aside from wind blowing it up no problems with wear.
I even used it to line stalls under shavings, but after about 5yrs it had holes, rips from the manure fork catching as I picked.
It DOES get slippery when there’s excessive humidity, but is thin enough so horses don’t slide walking on it when wet.
Their weight pushes it down into the stonedust enough so slippage is not an issue.
I have been known to almost take a header walking on it when it’s slick & I hurry.
