I am considering using rubber/cork combo flooring over concrete slab in my renovated kitchen. I placed floating cork planks over concrete slab in my office 10 years ago and, it spite of all the foot traffic and wheeling desk chairs, it still looks new. It has been a delight to my back to walk on, but I think I want more cushion from the rubber/cork flooring for my kitchen, since there will be far more standing than walking going on. Does anyone have experience with these products. Have looked at Capri Cork's site and others.
