I plan to use either a 3/4" sectional rubber mat, a one piece 3/4" rubber mat, or the "stable comfort" system. I like the idea of having the surface under the mat being porous!
For the porosity of the floor I am considering: stall grid/limestone dust/2b limestone/french drains, or in the place of the stall grids and limestone dust, using asphalt (which a local horse person claims to be porous) or using "pervious concrete" which a "concrete engineer" friend of mine suggested!
I worry that settling might occur with the stable grid/ limestone dust method, which would create a PITA situation under the rubber matting.
So......... anybody have experience with asphalt or porous concrete as stall flooring?
