you must have bought the hors stall matting that loked like black trash bag material.
i have som matting that is 10ys old as shields.. it actually is holding up better than truck mud flap, that I am also using.
what hold sup a lil better is conveyor belting.
PS.. the horse matting I use has cords in it.. you must be seeing that 'crumb' matt that is about 1/4" thick and just formed from composite rubber crumbs... I wouldn't line a ..well.. horse stall with that stuff.. :)
I use the thick extruded looking matting.. has bias cords in it like an old tire.
hard to cut.. I'd used a saw to cut up mine.
i really think we are talking about different products.
