Our detached garage (approx 20x20) has an asphalt floor (?!?). There is a concrete apron from the outside, over the 'threshold' and about 2 feet into the garage. The rest of the floor is asphalt that is uneven, pitted, and generally crappy. It gets warm enough in the garage that I have had a bicycle kickstand sink into the floor. An ideal floor (to me) is a simple concrete floor. I suppose a truckload of epoxy could be poured into the garage to even the floor as well.
I don't know how deep the asphalt is, and I suspect that it is simple fill underneath it. There are areas that dip 2-3 inches, maybe more. Probably a 5-6 inch difference between the highest and lowest spots. (That epoxy truck is sounding better.)
Short of digging up the asphalt and doing gravel base with rebar, and a concrete pour on top, any suggestions on how to improve this floor?
Thanks for any ideas!
